I can answer any general geology question (rocks, minerals, stratigraphy, geomorphology etc.). My expertise is in the geology of the Michigan Basin, PreCambrian, Paleozoic and Recent. I can answer questions concerning mining and petroleum exploration and production and the laws concerning those activities. I can also answer questions concerning stratigraphy of the Michigan Basin. I will also answer questions about mineral and rock collecting in the Basin. I won`t be able to answer many specific questions on hydrology, geophysics or geochemistry. I may be able to answer very general questions in those venues.
I have been working for the State of Michigan for 24 years as a Geologist and a Resource Analyst. I have experience with Subsurface Geology and Petroleum Geology, mining in Michigan, and Sand Dune Mining and Protection issues.

M&M hi, Very interesting rock! A slab or thin section would be very useful but I think it's probably a metamorphic rock. That's one that has undergone changes due to heat and pressure. The green mineral
Hi Carla, Looks like you have a rock called "banded quartzite". Very interesting specimen. Quartzite is a metamorphic rock; that's a rock that was changed from it's original material, usually through
Hi Wayne, Looks like you have a piece of granite there. It's one of the most common rock types on Earth. It's an igneous rock, which means it formed from liquid rock. It usually has lots of quartz
