Description Of Adaair Park Field Trip

Adair Park Field Trip was a really great experience where you get to see many different types of rocks and many diverse examples of minerals. This trip happened on Saturday November 1, 2014. Several geology classes went to the field trip for the expedition, with the purpose of learning the different types of each rock and its minerals and also to identify the stones from oldest to youngest. The group leaders of this trip were several professors of geology. Professor Croxen, Garrett, Dr. B, did everything possible for this trip to happen. Guess their goals for us were achieved because we had the experience to know more about how the mountains get build at the time with the movements of our nature and also to know how the rocks are made of. Once we arrived to Adair Park …show more content…
The minerals that we could identify in this rock were Quartz, Muscovite, and Potassium Feldspar. The intrusive body of the rock is Dike and one of the things we got to get for evidence was that this rock has schist and it’s weak and that it also cools slowly and by the time crystals get to be bigger and bigger. Then Upper and Lower Adair Formation comes with being younger. The younger of this two is the Lower Adair Formation with 30 million years old. Its color is red with sediments of Sandstones abd also with Sedimentary Breccia. The largest size of this rock is from about 4-6 inches. The minerals of the Lower Adair are Quartz, Feldspar, Gypsum, and Gneiss. This rock has Grypsum which is the line that divides the rock. The bedding is from about 4 inches to 2 feet and it is well defined. Moderately sorted and poorly sorted are kind of how the grains are and the shape of the grain is described as a sub angular. In this section we also checked the degree of compaction or cementation and for the lower is poorly cemented (crumbles in hand) or moderately cemented (forms cliffs), it all depends were you at. The type of cement material are Calcite (it fizz), Gypsum,
