In recent years, interest in Neoproterozoic glaciations has grown as their pivotal role in Earth system evolution has become increasingly clear. One of the main goals of the IGCP Project number 512 was to produce a synthesis of newly available information on Neoproterozoic successions worldwide. This Memoir consists of a series of overview chapters followed by site-specific chapters. The overviews cover key topics including the history of research on Neoproterozoic glaciations, identification of glacial deposits, chemostratigraphic techniques and datasets, palaeomagnetism, biostratigraphy, geochronology and climate modelling. The site specific chapters include reviews of the history of research on these rocks and up-to-date syntheses of the structural framework, tectonic setting, palaeomagnetic & geochronological constraints, physical, biological, and chemical stratigraphy, and descriptions of the glaciogenic and associated strata, including economic deposits.

Includes index to the genera and species described in the Palaeontologia Indica up to the year 1891.

Geological Society Memoir 52 records the extraordinary 50+ year journey that has led to the development of some 458 oil and gas fields on the UKCS. It contains papers on almost 150 onshore and offshore fields in all of the UK’s main petroliferous basins. These papers range from look-backs on some of the first-developed gas fields in the Southern North Sea, to papers on fields that have only just been brought into production or may still remain undeveloped, and includes two candidate CO2 sequestration projects. These papers are intended to provide a consistent summary of the exploration, appraisal, development and production history of each field, leading to the current subsurface understanding which is described in greater detail. As such the Memoir will be an enduring reference source for those exploring for, developing, producing hydrocarbons and sequestering CO2 on the UKCS in the coming decades. It encapsulates the petroleum industry’s deep subsurface knowledge accrued over more than 50 years of exploration and production.

FINALIST for the 2021 Oregon Book Award. Rooted in the Pacific Northwest, the essays in Ruby McConnell's Ground Truth: A Geological Survey of a Life cover the vast terrain of this region &– from volcanoes to city parks, the eroding shorelines along the Oregon coast, badlands, lush forests, and city parks. Combining her background as a registered geologist, McConnell's essays also weave in personal landscapes composed of grief, loss, and optimism for the future of our environment. "The Pacific Northwest that you see today is the result of forty years of radical changes in the culture and economics of what was once a resource-extraction and agriculture-driven region. They are changes so fundamental in nature and scope...that, for those of us from this place, will always be marked by the cataclysmic eruptions of Mt. St. Helens on May 18, 1980." --Ruby McConnell In this collection of 17 essays, geologist Ruby McConnell opens her part natural history, part memoir-in-essays about the Pacific Northwest with the cataclysmic eruption of Mt. St. Helens in May of 1980. She was two years old. "Everything that I have stood direct witness to since, everything I know about this place, happe

This memoir is the first to review all of Antarctica’s volcanism between 200 million years ago and the Present. The region is still volcanically active. The volume is an amalgamation of in-depth syntheses, which are presented within distinctly different tectonic settings. Each is described in terms of (1) the volcanology and eruptive palaeoenvironments; (2) petrology and origin of magma; and (3) active volcanism, including tephrochronology. Important volcanic episodes include: astonishingly voluminous mafic and felsic volcanic deposits associated with the Jurassic break-up of Gondwana; the construction and progressive demise of a major Jurassic to Present continental arc, including back-arc alkaline basalts and volcanism in a young ensialic marginal basin; Miocene to Pleistocene mafic volcanism associated with post-subduction slab-window formation; numerous Neogene alkaline volcanoes, including the massive Erebus volcano and its persistent phonolitic lava lake, that are widely distributed within and adjacent to one of the world’s major zones of lithospheric extension (the West Antarctic Rift System); and very young ultrapotassic volcanism erupted subglacially and forming a world-wide type example (Gaussberg).
