Late Paleozoic Glaciation And Ice Sheet Collapse Over Western And Eastern Gondwana: Sedimentology And Stratigraphy Of Glacial To Post-Glacial Strata In Western Argentina And Tasmania, Australia, Lindsey C. Henry

Theses and Dissertations

The late Paleozoic ice age (LPIA; 345-280 million years ago) provides the last complete record of a major deglaciation on a vegetated Earth, and therefore can serve as a proxy for Earth's inevitable transition out of its present glaciated state. This project analyzes climate change during and following the LPIA using two different approaches:

1) Detailed sedimentology analyses of five glacially-influenced formations in Argentina and Australia in order to determine the size and thermal regime of glaciers during the LPIA.

2) An investigation of massive volcanism along the Panthalassan margin of Gondwana as a source of CO2 that may have …
