Abstract
Carboniferous-Permian strata in basins within and proximal-to the Central Pangean Mountains (CPM) archive regional paleoequatorial climate during a unique interval in geological history (Pangean assembly, ice-age apex-and-collapse, megamonsoon inception). Whether these strata preserve a periglacial signal—or are periglacial in origin—remains debated. With a focus on upper Paleozoic (Upper Carboniferous – Permian) strata from the Lodève Basin, south-central Massif Central, France (eastern equatorial Pangea), this talk aims to address these questions through detailed sedimentology and a variety of analytical methods such as sediment geochemistry, detrital zircon geochronology, and cyclostratigraphy (time series analysis of magnetic susceptibility data). This work was supported by the National Science Foundation (NSF) under International Research Experiences for Students (IRES) grant OISE-1658614, the Sedimentary Geology and Paleobiology Program (EAR-1338331), and P2C2 (2103117).
Biography
Dr. Pfeifer is an assistant professor in the Department of Geology at Rowan University. Dr. Pfeifer is a geologist with expertise in sedimentology and paleoclimate. She studies ancient sedimentary basins, applying both traditional field methods and analytical techniques (e.g., geochronology, geochemistry, cyclostratigraphy, granulometry), to understand the climatic and tectonic processes that prevailed hundreds of millions of years ago (primarily in the Paleozoic world). Broadly, her research—from Western Europe to the midcontinent U.S.—illuminates aspects of the Earth’s climate system (e.g., long-term controls on carbon cycling) that have implications for understanding present and future climate solutions.
