Assessment of speleothem paleoenvironmental proxies using studies in modern karst systems
Sabato 22 Marzo 2008Announcement of Topical Session at the
Geological Society of America 2008 Annual Meeting
Houston, TX, October 5-9
The application of speleothems to studies of paleoclimatology, paleoenvironmental change and paleohydrology has greatly increased in the past decade due to the increased analytical speed and resolution available, as well as the need to generate precisely dated records of past environments.
Their use as proxies of past terrestrial environmental change includes published records of rainfall and temperature, vegetation dynamics, and atmospheric circulation such as tropical cyclones. Speleothem parameters analyzed to obtain these proxy records include speleothem calcite growth rate, trace elements, stable and (more…)
