September 16th PGS Meeting - Bedrock Geologic Mapping in the New England Applachians: Application to Tectonics, Water and Natural Resources
 

Presented by Gregory Walsh, United States Geological Survey, Montpelier VT The rocks in the New England Appalachians span 1.4 billion years of Earth history. Multiple episodes of deposition and erosion are attributed to repeated cycles of rifting and orogenesis. Major mountain building events with their associated deformation are punctuated by plutonism and metamorphism, all of which has produced a region underlain by highly complex geology. Geologic mapping has long been the key to unravelling the complex evolution of complicated rocks and, when combined with topical studies, has yielded not only scientific advances to the nature of mountain belts but also improvements to our understanding of groundwater and natural resources. This talk will highlight the regionís diverse tectonic history and provide case studies illustrating the links between geologic mapping and our natural resources.

See our speaker's abstract for more information.

Thanks to our March Speaker, David K. Brezinski, Maryland Geological Survey

In March our speaker, David K. Brezinski, who is the Appalachian stratigrapher and paleontologist for the Maryland Geological Survey, spoke on "Factors controlling karst development in the Great Valley of Maryland". See his paper on this subject at http://water.usgs.gov/ogw/karst/kig2002/dkb_stratigraphy.html. Our speaker's biography and abstract provides more information regarding this presentation.

News 
  Were there dinosaurs in Western Pennsylvania?  

Yes, dinosaurs walked on the land and left behind their footprints and bones, but unfortunately this evidence has been eroded away long ago. It is difficult to imagine the enormous amount of soil and rock that has been carried away by weathering processes in the 60 million years since the end of Cretaceous time. Scientists have estimated that a layer of rock over a mile thick has been eroded since the beginning of the Mesozoic Age and with it all traces of the dinosaurs.

See Dr. John Harpers more thorough explanation for more information.
