Previously thought to form part of the Archean Rae Craton, and later referred to as the Southeastern Churchill Province, it has been regarded as an ancient continental block trapped between the Paleoproterozoic Torngat and New Quebec orogens, with its relationships to the adjacent Superior and North Atlantic cratons remaining unresolved. The geochronological data presented herein suggest that the Archean evolution of the Core Zone was distinct from that in both the Superior and North Atlantic (Nain) cratons. Moreover, the Core Zone itself consists of at least three distinct lithotectonic entities with different evolutions, referred to herein as the George River, Mistinibi-Raude and Falcoz River blocks, that are separated by steeply-dipping, crustal-scale shear zones interpreted as paleosutures. Specifically, the George River Block consists of ca. 2.70 Ga supracrustal rocks and associated ca. 2.70–2.57 Ga intrusions. The Mistinibi-Raude Block consists of remnants of a ca. 2.37 Ga volcanic arc intruded by a ca. 2.32 Ga arc plutonic suite (Pallatin) and penecontemporaneous alkali plutons (Pelland and Nekuashu suites). It also hosts a coarse clastic cover sequence (the Hutte Sauvage Group) which contains detrital zircons provided from locally-derived, ca. 2.57–2.50 Ga, 2.37–2.32 Ga, and 2.10–2.08 Ga sources, with the youngest concordant grain dated at 1987 ± 7 Ma. The Falcoz River Block consists of ca. 2.89–2.80 Ga orthogneiss intruded by ca. 2.74–2.70 granite, tonalite, and granodiorite. At the western margin of the Core Zone, the George River Block and Kuujjuaq Domain may have been proximal by ca. 1.84 Ga as both appear to have been sutured by the 1.84–1.82 Ga De Pas Batholith, whereas at its eastern margin, the determination of metamorphic ages of ca. 1.85 to 1.80 Ga in the Falcoz River Block suggests protracted interaction with the adjacent Lac Lomier Complex during their amalgamation and suturing, but with a younger, ‘New Quebec’ overprint as well. The three crustal blocks forming the Core Zone add to a growing list of ‘exotic’ Archean to earliest Paleoproterozoic microcontinents and crustal slices that extend around the Superior Craton from the Grenville Front through Hudson Strait, across Hudson Bay and into Manitoba and Saskatchewan, in what was the Manikewan Ocean realm, which closed between ca. 1.83–1.80 Ga during the formation of supercontinent Nuna.

There are also times when I ask myself the very same question, but it usually boils down to this – being a geologist provides opportunities to visit inspiring, unique and often remote locations through field work and other field trips. In Scotland a couple of years ago, on a conference trip that led to the following article, I read Stephen Baxter’s excellent book Revolutions in the Earth. I thoroughly recommend it – as a biography of James Hutton it gives some insight into his personality – and it illustrates the love-hate relationship that geologists have with field work. In a letter written to a friend, Hutton complained “Lord pity the arse that’s clagged to a head that will hunt stones”. I could amplify this with a detailed footnote explaining the meaning of the archaic dialect verb to clag, but I don’t need to because all geologists will understand Hutton’s sentiment. We don’t really have a choice in this – our interest in exploring the natural world is just part of who we are. Such a conclusion may not be fully scientific, but there’s no denying its truth. Even in a technological age where some geoscience careers are built around black boxes and vast computer models, geology remains at its core an observational science, and the theories that we build are ultimately subject to the ground truth of field observations. It was the lure of field work, the outdoors and travel that brought me into geology, and I know that the same is true for many of my colleagues. Modern geoscience may be sophisticated, multidisclipinary and quantitative, but it always links back to careful field observations and their thoughtful interpretation. Even if technology gives us details and constraints, the essential plotline of the story of Earth comes from reading the rocks. Geoscientists are generally keen and adaptable travellers, who like to get off the beaten tourist paths, sometimes at their own peril. One of the great things about being a student of the Earth is that it surrounds us, and there will always be something interesting to find out, wherever we roam. We enjoy a special relationship with the Earth because we understand its dynamic nature and can visualize it in four dimensions. Travelling geologists are always glancing surreptitiously at roadside outcrops as they flash by, or asking exactly why that range of hills is where it is and shaped just so. This can at times be a source of great frustration to our families or our travelling companions, but it is a natural expression of our curiosity about all things that connect to earthly processes. The one thing that I fear most in aging is to lose such curiosity, as happened to my father. Our idea for a new series in Geoscience Canada that can provide helpful travel information and thoughtful geological context for influential o","PeriodicalId":55106,"journal":{"name":"Geoscience Canada","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46723644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The question is, when a duty of care exists, what is the standard of care that is owed? Geoscience regulators in Canada and around the world are working with geoscientists to develop innovative solutions in establishing the standard of care that must be met. By clearly establishing what our expectations are concerning standard of care, we are setting common ideals and goals as a professional community. Both society, geoscientists and employers of geoscientists look to regulatory associations for guidance on professional practice, therefore regulators need to strive to support and educate their members by developing tools and resources that allow members to meet the standard of care expected of them.

Waltho","doi":"10.12789/GEOCANJ.2017.44.126","DOIUrl":"https://doi.org/10.12789/GEOCANJ.2017.44.126","url":null,"abstract":"As professional communities around the world, geoscientists have in place disciplinary measures and, over time, instances have occurred which have required disciplinary actions to be taken against individuals. Geoscientists have specialized knowledge and provide expertise on which others rely for important decision- making. Geoscientists are best positioned to judge the scientific/technical and ethical merits of the work of other geoscientists. They are considered professionals and for that reason, society has placed the onus on the profession to govern itself. Consequently, it is important that appropriate disciplinary procedures are in place, that they are ever improving, and that the profession can and does act decisively when necessary.  This two-part review paper examines systems and measures to uphold the ethical conduct of geoscientists (Part 1), and studies actions taken against geoscientists in the last three decades (Part 2). It uses available information collected from the member organizations of the International Union of Geological Sciences’ Task Group on Global Geoscience Professionalism as well as public sources.  Models used for the governance and self-regulation of geoscience practice vary globally across the same spectrum that is typical in other professions, with the choice of model varying to suit local legal contexts and societal needs and norms. Broadly, similar processes for complaints, investigation, and disciplinary decision-making (and appeals of decisions) are used. The types of charges that can be made for offences or allegations are similar. The ranges of applicable penalties vary depending on the extent of statutory power in place, but beyond this constraint, there are many parallels.  Ninety-two documented cases are identified where action has been taken against geoscientists globally since 1989. Of these, 40 relate to either non-payment of dues or fees (usually discontinuation of a membership or license) or to non-compliance with Continuing Professional Development requirements. The remaining 52 are actions for more serious offenses, resulting in penalties that are more substantial. These offences cluster into six categories: 1) falsifying data; 2) fraudulent billing and/or falsifying time sheets; 3) inappropriate behaviour towards others; 4) problematic geoscience work and/or technical deficiencies; 5) misrepresentation of findings, or the giving of unsupported opinions; and 6) mixed other offences. The most frequently used penalty in these cases is the reprimand. Next most frequent is revocation. Revocations include resignations with prejudice, where the geoscientist chose to resign their membership rather than allow the matter to proceed to discipline. Suspensions, requirements for remedial education and/or fines are also frequent penalties. Combinations of different penalties are common.  It is evident that rigorous procedures are in place in a number of countries and that they are being used to address the unp","PeriodicalId":55106,"journal":{"name":"Geoscience Canada","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43457489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The three projects were in the field of environmental geoscience. In all three cases, the solution proposed by a Professional Geoscientist (P.Geo.) was opposed by a representative of a regulatory body that held authority for approval. The final outcomes that were approved by the regulator were less protective of human health (increased exposure to potential contaminants) and/or the environment (more resources used; higher contaminant exposure). In two of the three cases, the solutions were also more expensive to the client and the taxpayer. This paper explores the practice of professionalism in geoscience versus regulatory authorities that hold jurisdiction over geoscience in a broad sense. In each of the three cases, the professional opinions and analysis of the P.Geo. working for a private sector client were overridden by a professional (P.Geo. or Professional Engineer) in an approval authority. These three studies highlight the ethical decisions required by professional geoscientists in the face of regulators who hold control over areas of geoscience. Although the training of professionals is similar, regulators appear to be influenced by perceived risk as opposed to actual risk based on scientific evidence. Similarly, some policies do not have a solid scientific basis. As a result, sound scientific reasoning and resulting rational decisions may be hindered in regulatory decision-making.

These ocean basins are connected through the Davis Strait, a bathymetric high comprising primarily continental lithosphere, and the focus of the West Greenland Tertiary volcanic province. It has been suggested that a mantle plume facilitated this breakup and generated the associated magmatism. Plume-driven breakup predicts that the earliest, most extensive rifting, magmatism and initial seafloor spreading starts in the same locality, where the postulated plume impinged. Observations from the Labrador Sea–Baffin Bay area do not accord with these predictions. Thus, the plume hypothesis is not confirmed at this locality unless major ad hoc variants are accepted. A model that fits the observations better involves a thick continental lithospheric keel of orogenic origin beneath the Davis Strait that blocked the northward-propagating Labrador Sea rift resulting in locally enhanced magmatism. The Davis Strait lithosphere was thicker and more resilient to rifting because the adjacent Paleoproterozoic Nagssugtoqidian and Torngat orogenic belts contain structures unfavourably orientated with respect to the extensional stress field at the time.RESUMELa cassure entre le Groenland et le Canada a entraine une expansion oceanique de la mer du Labrador et de la baie de Baffin.

Rocks are complex composite mixtures for which the basic building blocks are grains of minerals. The properties of the minerals, how they are bound together, and many other aspects of rock texture affect the entire mining value chain from exploration, through mining and processing, waste and tailings disposal, to refining and sales. This review presents rock properties (e.g. strength, composition, mineralogy, texture) significant in geometallurgy and examples of test methods available to measure or predict these properties.   Geometallurgical data need to be quantitative and spatially constrained so they can be used in 3D modelling and mine planning. They also need to be obtainable relatively cheaply in order to be abundant enough to provide a statistically valid sample distribution for spatial modelling. Strong communication between different departments along the mining value chain is imperative so that data are produced and transferred in a useable form and duplication is avoided. The ultimate aim is to have 3D models that not only show the grade of valuable elements (or minerals), but also include rock properties that may influence mining and processing, so that decisions concerning mining and processing can be made holistically, i.e. the impacts of rock properties on all the cost centres in the mining process are taken into account. There are significant costs to improving ore deposit knowledge and it is very important to consider the cost-benefit curve when planning the level of geometallurgical effort that is appropriate in individual deposits.RESUMELa geometallurgie est une science interdisciplinaire qui s’interesse aux caracteristiques de la masse rocheuse qui influent de maniere significative sur l'exploitation miniere et le traitement du minerai.

Entry to practice competencies are the abilities required to enable effective and safe entry-level practice in a profession. In 2012, Geoscientists Canada received funding from the Government of Canada’s Foreign Credentials Recognition Program. A central component of the funding involved the development of a competency profile to assist in assessment for licensing in the geoscience profession. Work concluded with the approval of the Competency Profile for Professional Geoscientists at Entry to Practice by Geoscientists Canada in November 2014. The Competency Profile comprises concise statements in plain language, setting out the skills and abilities that are required to be able to work as a geoscientist, in an effective and safe manner, independent of direct supervision. It covers competencies common to all geoscientists; competencies for the primary subdisciplines of geoscience (geology, environmental geoscience and geophysics); and a generic set of high level competences that can apply in any specific work context in geoscience. The paper is in two parts. Part 1 puts the concept of competencies in context and describes the approach taken to develop the profile, including: input from Subject Matter Experts (practising geoscientists representing a diverse sampling of the profession); extensive national consultation and refinement; and a validation procedure, including a survey of practising Canadian geoscientists. Part 2 introduces the profile, explains its structure, and provides examples of some of the competencies. The full competency profile can be obtained from the Geoscientists Canada website www.geoscientistscanada.ca.  Future work will identify specific indicators of proficiency related to each competency and suggest appropriate methodologies to assess such competencies. It will also involve mapping the profile to the existing Canadian reference standard, Geoscience Knowledge and Experience Requirements for Professional Registration in Canada.RESUMELes approches d'evaluation basees sur les competences en vue de l'inscription professionnelle refletent l'abandon par les professions, tant au Canada que partout dans le monde, des evaluations classiques basees sur les titres de competences et axees sur une combinaison de realisations academiques et de temps de pratique supervisee.
