Abstract Details

2018, MS, University of Cincinnati, Arts and Sciences: Geology.
In this study, the question of microenvironmental change related to the overall eruption pattern from the Siberian Traps was examined. Using the unique rare earth element geochemistry that was produced from the successive eruptions, a geological trace that links the Siberian Traps to the environmental collapse from the effects of windblown ash was found in using over 400 marine sediment samples taken from 7 different Permian-Triassic Boundary sections. The following results show values likely indicative of material derived from the lower crust, upper mantle with the Eu/Eu* anomalies from Zal, a microcontinent in the Tethys Ocean, Gujo-Hachiman, an open ocean site in the eastern Panthalassic Ocean, along with Guryul Ravine and Spiti on the northwestern margin of Gondwana. These results represent a global signal, and could reflect a deleterious effect upon marine and terrestrial ecosystems from the possible volcanic ashfall that was produced from the Siberian Traps.
