Folks, Here is an announcement on a presentation by Dr. Lehrmann.
Thought you might like to see this. Geary Edwards Aquifer Philosophical Society - aka brown bag luncheon Friday, August 5, 2016 at 11:55 AM. Permian-Triassic Marine Carbonate Platforms and Karst Features of the Nanpanjiang Basin, Guizhou, Guangxi and Yunnan, South China By Dan Lehrmann, Ph.D. At Edwards Aquifer Authority Training Room 900 E Quincy Street, San Antonio, TX 78215 Dr. Dan Lehrmann will make a presentation titled: Permian-Triassic Marine Carbonate Platforms and Karst Features of the Nanpanjiang Basin, Guizhou, Guangxi, and Yunnan, South China." Friday, Agusut 5, 2016 at 11:55 AM. The presentation will be held in the Training Room at the Edwards Aquifer Authority, 900 E. Quincy Street, San Antonio, Texas. These are informal presentations so please feel free to bring your lunch. You may also contact the EAA at 210.222.2204 or www.edwardsaquifer.org<http://www.edwardsaquifer.org/> for additional directions. If you are traveling a long distance for the talk, I would recommend that you call our receptionist at 210.222.2204 that morning to make sure that the talk is still scheduled. On very rare occasions, we have had to cancel or move the talk. I apologize for any inconvenience this may cause. Abstract Unique exposures in the karst terrain of a large carbonate shelf borders the basin and several isolated carbonate platforms within the basin contain a history of more than 20 million years, with over 3 km of thickness. The basin experienced active tectonics, the greatest mass extinction of the Phanerozoic and major changes in climate and ocean chemistry. The area is therefore a natural laboratory for investigating the mechanisms controlling carbonate platform evolution and architecture. Spectacular karst features are evident from the macro to micro scale and include: conical towers, tower karst plateaus, karst valleys and sinkholes, deep gorges, underground rivers, spectacular caves, and rock forests. Karst forms are especially dramatic at carbonate platform margins where there are rapid changes in facies from densely cemented platform limestone to deep-marine non-carbonate lithologies. Biography Dan Lehrmann is the Pyron Professor of Geoscience at Trinity University. He is originally from Wisconsin where he taught at the University of Wisconsin-Oshkosh. He specializes in carbonate sedimentology and paleontology. He has conducted geological research in south China for 25 years. Thank you.
