Hot Spring environments and ecosystems
Grand Prismatic hot spring - Yellowstone NP Wyoming
My research broadly focuses on hot
spring ecosystems and how they become fossilised. My early research
career centered on investigations of active hot springs in Yellowstone
National Park where I studied the process of silicification in higher-plants.
During this work it became apparent that in active hot spring areas
plants are most commonly preserved in wetlands that surround most
thermal areas.
During the following years my work investigated these wetland areas, their plants and animals, geochemistry and fossilisation processes. Currently I am searching for fossil examples of geothermal wetlands in the 150 million year old volcanic rocks of the Deseado Massif, Argentine Patagonia.
