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 rate was formed was the Leatherwood Granite dictated shtup Food Lion. beneficial from outward appearance at that put up were obvious weathering and fractures with filled in sediments. Also the surface of these disputations was rough and had a phaneritic texture payable to the moderate but obvious crystals. Without any layering and the visible lucid structure in these stones it was reason that this site consisted of igneous reels. find these rocks there were differences in ripening due to the filled in fractures between each slit of the site. These fractures show there were volcanic activity melting from the mother fucker consequently cooled down allowing unlike sediments fill in the cracks then molding in rear with the igneous structure presentation the sequence of eve nts. Second obvious observation was the two variant origins of the rocks, mainly mafic but there was a small incision that was felsic. Looking at the felsic rock closer I apothegm that the mafic rocks surrounding it were intruding the felsic rock showing that the mafic rocks are young than the felsic rock.
After collecting and observe the data from the Leatherwood Granite foot Food Lion, we went to the Fork Mt. Gneiss. This site was large and had many mixed regions showing how it heated from the loafer creating the foliation lines and xenoliths. The very perceptible foliation and the red garnets located at the b ottom of the site implied that the rocks wer! e metamorphic . These attributes show that the rock on the bottom had convey extremely hot and melted. The metamorphism is regional. The two rocks varied because of the temperature during the creation of the rocks. The elucidate was foliated, the minerals lined up from pressure and enough heat to imbibe it layer and not melt. The bottom showed that the heat source was from the bottom. push through of the...If you want to get a full essay, order it on our website: OrderCustomPaper.com
