Live Poster Session: Zoom LinkThursday, July 30th 1:15-2:30pm EDT Abstract: Much of the sediment on Venus’ surface is derived from impact cratering. Such sediment is ejected into the planet’s atmosphere during impact events and eventually settles on the surface in a parabola-shaped deposit. Although these ejecta deposits have been mapped, the total amount of sediment … Read more

Live Poster Session: Zoom LinkThursday, July 30th 1:15-2:30pm EDT Abstract: Stable carbon and nitrogen isotopes can reveal information about the paleoenvironmental history of lakes and their surrounding regions. Human activity has contributed significantly to environmental degradation within lake systems. The process of eutrophication, where excess nutrient inputs trigger abundant algal growth, is often linked to … Read more

Live Poster Session: Zoom LinkThursday, July 30th 1:15-2:30pm EDT Abstract: Pseudotachylite is a friction-induced glassy fine-grained rock observed in exhumed fault zones, and it has become the unequivocal evidence for high slip rate seismic activity in the past. Immediately after the nucleation of an earthquake, the wall rocks along the fault plane accelerates to high … Read more

Abstract: Pore waters extracted from lake sediments provide valuable information about environmental conditions, nutrient flow, climate history, and biogeochemical processes occurring in the sediment, as well as the overlying water column. While the chemistry of marine sediments has been studied extensively, there have been decidedly fewer studies examining early diagenesis of lake sediments, despite the … Read more
