Paleoclimate Controls Near-surface Dolomite Abundance

Peritidal dolomites of the Upper Triassic sequence in the Transdanubian Range, Hungary, preserve evidence of climate change. Recurring subaerial exposure, related to sea-level change, controls the aerial extent of dolomitization of platform carbonates, a drier climate favors dolomite formation, while increasing humidity leads to decreasing intensity of early dolomitization.

My contributions to this project included cathodoluminescence petrography, fluid inclusion microthermometry, sample preparation for stable carbon and oxygen isotope analysis, data interpretation, and manuscript preparation (developmental editing and graphic design).
