Spring 2006 Historic Geology Field Trip around Presque Isle

Spring 2006 Historic Geology Field Trip around Presque Isle

April 20, 2006, led by Professors Chunzeng Wang and David Putnam

A geologic trip was organized for students in Historic Geology around Presque Isle area in April 20, 2006. The trip was very successful. It was the first geologic field trip for most of the students in the class. The following pictures show how much they enjoyed the trip.

Preparation for the field trip got great help from Professor Bill Forbes, a retired UMPI geologist. Professor David Putnam joined the trip and helped explaining local glacial geology in the field. Both of them are thanked.

Stop 2 at Donald Maynard Quarry by Parsons Road. The lower quarry for gravel and sand (right) and the upper quarry for bed rocks (left).


Joey: Is this a calcite vein inside the tonalite? Dave: Yes, you are right. Stop 2 at Donald Maynard Quarry by Parsons Road	Discussion on the tonalite, a felsic intrusive/plutonic igneous rock. Stop 2 at Donald Maynard Quarry by Parsons Road

Stop 5 at an abandoned quarry at Edmunds Hill for Chapman Formation sandstone and volcanic/extrusive andesite. Chapman sandstone beds are nearly vertical.	Looking for brachiopods fossils in Chapman sandstone at Stop 5.

Another nice shoot for Elizabeth, spheroidal weathering and Chapman sandstone at Stop 5.	The quarry and the spheroidal weathering of Chapman sandstone at Stop 5, Edmunds Hill.
