These tectonic and climatic events caused dramatic sea-level fluctuations and climate changes and produced a Carboniferous world that was diverse topographically and climatologically, perhaps only rivalled in that diversity by the late Cenozoic world. Furthermore, the Carboniferous was a time of the accumulation of vast coal deposits of great economic and societal significance. The temporal ordering of geological and biotic events during Carboniferous time thus is critical to the interpretation of some unique and pivotal events in Earth history. This temporal ordering is based on the Carboniferous timescale, which has been developed and refined for nearly two centuries. This book reviews the history of the development of the Carboniferous chronostratigraphic scale and includes comprehensive analyses of Carboniferous radioisotopic ages, magnetostratigraphy, isotope-based correlations, cyclostratigraphy and timescale-relevant marine and non-marine biostratigraphy and biochronology.","PeriodicalId":22055,"journal":{"name":"Special Publications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83792384","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}

Well-known for hosting economic minerals and elements such as diamonds, base metals, gold and platinum-group elements, they are also significant for our understanding of deep-mantle processes, such as mantle metasomatism and mantle plume–lithosphere interactions, as well as large-scale geodynamic processes, such as subduction-related tectonics, and supercontinent amalgamation and break-up. This book aims to provide a timely overview of the state-of-the-art and recent advances as achieved by various research groups around the world.

The first section is devoted to studies focusing on the distribution of isotopes in precipitation, groundwater, lakes, rivers, springs, tap water, mine water and their relationship with terrestrial environments at regional to continental scale. In relation to this, the second section includes case studies from a range of continental settings, investigating cave deposits (stalagmites, bat guano), animal skeletons (dinosaurs, alligators, turtles, bivalves), present and past soils (palaeosols) and limestones. The sections focus on the interaction between the surficial water cycle and underground water storage with deposits acting as archives of short- to long-term climatic and environmental changes.

Klausen","doi":"10.1144/SP518-2021-22","DOIUrl":"https://doi.org/10.1144/SP518-2021-22","url":null,"abstract":"Abstract The decompressional release of magma at continental triple-rift break-up, large igneous province (LIP) centres, above mantle plume stems, results in highly magmatic settings. As a particularly well-exposed example, it is proposed that the East Greenland coastal dyke swarm preserves a structural record of how dyke dilations v. tectonic extension increased upon approaching its Kangerlussuaq triple rift centre. Such more magmatic break-up is reflected by how abruptly its volcanic rifted margin transitions into 100% dykes, and, in this case, up to 100 km further inland than its geophysically determined continent–ocean boundary. Correspondingly high magma flux through an igneous Kap Edward Holm centre sustained the lateral injection of up to 150 km-long dykes, evidenced by increased cut-off dyke thicknesses, below which there is an anomalously low abundance of thinner dykes, that conform to the cube root of their thermal arrest distance. Only the thickest and, thereby, longest dyke injections linked up with a more southerly located igneous Imilik centre of an en echelon offset dyke swarm, the complex transition into which is also addressed. This highly magmatic central plumbing system is further compared to similar volcanic zones across Iceland and other post-Paleozoic break-up LIPs in order to contextualize its importance.","PeriodicalId":22055,"journal":{"name":"Special Publications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77913570","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}
