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 post was formed was the Leatherwood Granite dictated toilet Food Lion. beneficial from outward appearance at that correct were obvious weathering and fractures with filled in sediments. Also the surface of these disputations was fractious and had a phaneritic texture payable to the moderate but tangible crystals. Without any layering and the visible lucid structure in these stones it was reason out that this site consisted of igneous reels. find these rocks there were differences in senescence due to the filled in fractures between each constituent of the site. These fractures show there were volcanic activity melting from the whoreson because cooled down allowing unlike sediments fill in the cracks then molding in rear with the igneous structure viewing the sequence of events. Second obvious observation was the two diametric origins of the rocks, mainly mafic but there was a small naval division that was felsic. Looking at the felsic rock closer I motto that the mafic rocks surrounding it were intruding the felsic rock showing that the mafic rocks are younger than the felsic rock. After collecting and observe the data from the Leatherwood Granite hobo Food Lion, we went to the Fork Mt. Gneiss. This site was large and had many respective(a) regions showing how it heated from the loafer creating the foliation lines and xenoliths. The very noticeable foliation and the red garnets located at the bottom of the site implied that the rocks were metamorphic . These attributes show that the rock on the bottom had take extremely hot and melted. The metamorphism is regional. The two rocks varied because of the temperature during the creation of the rocks. The evanesce was foliated, the minerals lined up from pressure and enough heat to dissemble it layer and not melt. The bottom! showed that the heat source was from the bottom. divulge of the...If you want to get a full essay, order it on our website: BestEssayCheap.com
