It is the starting point for stratigraphic and structural interpretations, metamorphic facies, geochronology and modelling studies - and underpins civil engineering. From the beginning, geological mapping rapidly evolved into far more than being a simple spatial catalogue of observable rock types and landforms on the Earth's land-surface; deductive reasoning allowing this knowledge to infer subsurface Earth structure. The same approaches are down-scaled to deduce processes on the grain-scale; or up-scaled to look out to extra-terrestrial objects. This is an introduction to fourteen papers in this Special Publication that celebrates geological mapping, its historical importance and future directions, and its use in applied geology together with developing knowledge of Earth and planetary evolution and processes.

However, the long-term post-cooling legacy of subvolcanic intrusions on fluid flow received much less attention. Here we describe geological examples in the Andean foothills, Argentina, showing that igneous intrusions have long-term effects on fluid flow after their emplacement and cooling. The case study consists of ∼11-million-year-old, eroded andesitic intrusions of Cerro Alquitrán and Cerro La Paloma, northern Neuquén Basin, Argentina, at the rims of which large volumes of bitumen are naturally seeping out at the Earth’s surface. The intrusions exhibit laccolithic shapes with steep-sided contacts with the host rock. Near the intrusive contacts, the andesite is intensely broken along concentric breccia bands and fracture bands, interpreted to result from syn-emplacement brittle magma deformation,which represent high-permeability pathways for the migrating bitumen. Organic geochemical analyses of the bitumen show that the seeping oils were generated from incipiently mature Vaca Muerta sections located in a regional kitchen to the west, implying a lateral migration of ∼10-20 km. The Cerro Alquitrán and Cerro La Paloma intrusions are demonstrative examples highlighting how extinct subvolcanic intrusions have long-term consequences on subsurface fluid circulations in sedimentary basins.","PeriodicalId":281618,"journal":{"name":"Geological Society, London, Special Publications","volume":" 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139622110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A complete and well-preserved Cretaceous pelagic composite succession (CPCS) of this area is here presented. It has been constructed through the integration of the well-established magnetostratigraphy with the planktonic foraminiferal biostratigraphy based on previous and newly identified events from six key sections and one drill core. The recovery of planktonic foraminifera successfully disaggregated from the hard lithologies allows the identification and precise placement of several primary and secondary bioevents. In particular, the record of the identified bioevents counts thirty-five primary biohorizons, which allow the subdivision of the studied succession into thirty-four zones and four subzones. Following this study and previous findings on Cretaceous planktonic foraminifera, an updated planktonic foraminiferal zonation for the Cretaceous Period is proposed. This refined magnetobiostratigraphic framework, which in this study is integrated with the Cretaceous inoceramid, anoxic, and carbon-isotope events recognized in the Umbria-Marche Basin, may provide an invaluable tool for improving Cretaceous correlations at low to middle latitudes, as well as palaeoenvironmental, palaeoclimatic and palaeoceanographic interpretations.","PeriodicalId":281618,"journal":{"name":"Geological Society, London, Special Publications","volume":"56 21","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139533105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Observed heat-flow values however, do not always comply with classic rifting models. Here, we use 2D numerical models to investigate the relationship between rifting, sedimentation and thermal history of margins. We find that during the synrift, the basement heat flow and temperature are not only controlled by extension factor, but also by synrift sediment thickness and the evolution of deformation. As this progressively focuses oceanward, the proximal sectors thermally relax, while the distal sectors experience peak temperatures. In the postrift, the lithosphere under the hyperextended margins does not return to its original state, at least for ∼100 Myrs after breakup. Instead, it mimics that of the adjacent oceanic plate, which is thinner than the original continental plate. This results in heat flow increasing oceanward at postrift stages, when classic rifting theory predicts complete thermal relaxation. Our models also predict slightly increased heat flows in the adjacent oceanic crust, potentially extending hydrocarbon plays into distal margins and oceanic crust, previously discarded as immature. Finally, our models indicate that commonly used temperature approximations to calculate heat-flow during rifting, may strongly differ from those occurring in nature.

The possible productivity of these ‘unconventional’ reservoirs was recognized by studying outcrops and well data of sills and dikes emplaced in different formations of the fold and thrust belt of the northern Neuquén Basin. Mudlogging control, as well as the evaluations with drill stem tests (DST), were decisive to define these reservoirs as prospective. From petrographic reports on samples from outcrops and cores, six lithological types could be distinguished in the igneous units for this region. Recent works confirm that this volcanism belongs to two predominant cycles from the late Oligocene to the Miocene (“Molle”) and middle to upper Miocene (“Huincán”).

This study investigated the petrography and petrophysical characteristics of 60 volcaniclastic and 4 siliciclastic samples from three Paleogene volcanic provinces - East Greenland, Faroe Islands, and Ethiopia. The volcaniclastic samples have highly variable helium porosities (average: 25.2%), but negligible total optical porosities (average: 1.9%) implying reduced reservoir potential. The samples have, however, highly variable air permeabilities (average: 11 mD) suggesting they could make tight reservoirs. The permeabilities are related to either early calcite cements or the devitrification of volcanic glass. Mercury Injection Capillary Pressure (MICP) data was collected for a subset of 33 samples that at leakage/breakthrough saturations could, under near-surface conditions, hold oil column heights of between 4 m and 1181 m (average: 240 m). The best seals consistently have zeolite contents of >20 vol.% due to their small pore throat radii. Conversely, the worst seals are dominated by smectite and a conspicuous absence of zeolite minerals. The zeolite-rich volcaniclastic rocks could, therefore, make good shallow seals.

Understanding the evolution of the 3D structural framework through time is fundamental for all forms of subsurface exploration across the energy transition. The aim of this paper is to show how 2D geospatial databases can represent the 4D deformational record. This is by capturing the three components of deformation: the initial state of the crustal architecture to be deformed (the pre-deformational crustal facies and structural framework), the processes responsible for the deformation (geodynamics), and the products of the deformation (folds, faults, magmatism, and crustal facies). Deformation is not limited to a single tectonic cycle. Within each cycle, it is time-transgressive and highly variable spatially. By evolving these 2D geospatial databases through time using restoration and plate modelling, we can better understand the 4D complexity of deformation and how this impacts exploration.","PeriodicalId":281618,"journal":{"name":"Geological Society, London, Special Publications","volume":"41 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139173992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
