We have an early morning tomorrow, since we’re running our NE-SE GSA field trip for the Pennsylvania Geological Survey. So, this post will be short and sweet. Here are a few of the highlights from today’s diabase escapades:
One of Betty Lou's cores that we cut for geochemistry and thin sections.
More awesome slickenfibers.
Contact between diabase and a felsic layer.
Quarry workers drilling holes to set up for the next blast.
