Virginia Geology

Michael Rivera Physical Geology 9/26/2011 Virginia Geology The first aim we vi directd for analyzing the go out and sequence of events leading up to decision making the results of how each point was formed was the Leatherwood Granite dictated in arrears Food Lion. beneficial from outward appearance at that level were obvious weathering and fractures with filled in sediments. Also the surface of these disputations was peevish and had a phaneritic texture payable to the moderate but plain crystals. Without any layering and the visible lucid structure in these stones it was cerebrate that this site consisted of igneous reels. find these rocks there were differences in senescent due to the filled in fractures between each role of the site. These fractures show there were volcanic activity melting from the mother fucker then cooled down allowing unlike sediments fill in the cracks then molding in rear with the igneous structure covering the sequence of event s. Second obvious observation was the two assorted origins of the rocks, mainly mafic but there was a small sectionalization that was felsic. Looking at the felsic rock closer I adage that the mafic rocks surrounding it were intruding the felsic rock showing that the mafic rocks are jr. than the felsic rock.

After collecting and observe the data from the Leatherwood Granite behind(predicate) Food Lion, we went to the Fork Mt. Gneiss. This site was large and had many motley regions showing how it heated from the loafer creating the foliation lines and xenoliths. The very discernible foliation and the red garnets located at the bottom of the site im! plied that the rocks were metamorphic . These attributes show that the rock on the bottom had gravel extremely hot and melted. The metamorphism is regional. The two rocks varied because of the temperature during the creation of the rocks. The egest was foliated, the minerals lined up from pressure and enough heat to fall in it layer and not melt. The bottom showed that the heat source was from the bottom. let out of the...If you want to get a full essay, order it on our website: BestEssayCheap.com
