Comparing Middle Permian And Early Triassic Environments: Mud Aggregates As A Proxy For Climate Change In The Karoo Basin, South Africa, Bryce Pludow
Honors Theses
The Permian-Triassic Boundary (252.6 Ma) is an interval under intense study as changes across it represent the greatest loss of life in Earth history. Although the event is well understood and constrained in the marine realm, questions remain about extinction, climate, and environmental conditions on land. The Karoo Basin of South Africa is a focus of study due to the complete nature of its terrestrial record, specifically across this boundary.
The identification of pedogenic mud aggregates document the presence of soils with abundant clays produced in a seasonally arid environment. The occurrence of these aggregates in low-sinuosity Early Triassic fluvial …
