This area exposes about 9000 feet of sedimentary rocks ranging in age from Cambrian to Cretaceous. All the formations are well described. The area covered by the report is approximately 1800 square miles, is noted for its oil and gas resources, and is also host to significant gypsum deposits. One of the cross sections (shown in pictures) notes areas where large cavities lined with calcite crystals were encountered.

Expert packing assured. The recent increase in postage rates was pretty big. As a result, Media Mail is now my default shipping method to keep shipping affordable.
