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 state of affairs was formed was the Leatherwood Granite dictated lowlife Food Lion. beneficial from outward appearance at that drive were obvious weathering and fractures with filled in sediments. Also the surface of these disputations was uncouth and had a phaneritic texture payable to the moderate but megascopic crystals. Without any layering and the visible lucid structure in these stones it was cogitate that this site consisted of igneous reels. find these rocks there were differences in aging due to the filled in fractures between each department of the site. These fractures show there were volcanic activity melting from the can because cooled down allowing unlike sediments fill in the cracks then molding in rear with the igneous structure screening the sequence of events. Second obvious observation was the two opposite origins of the rocks, mainly mafic but there was a small department 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 young than the felsic rock.

After collecting and observe the data from the Leatherwood Granite canful Food Lion, we went to the Fork Mt. Gneiss. This site was large and had many various(a) regions showing how it heated from the loafer creating the foliation lines and xenoliths. The very marked foliation and the red garnets located at the bottom o f the site implied that the rocks were metam! orphic . These attributes show that the rock on the bottom had work extremely hot and melted. The metamorphism is regional. The two rocks varied because of the temperature during the creation of the rocks. The roundabout was foliated, the minerals lined up from pressure and enough heat to execute it layer and not melt. The bottom showed that the heat source was from the bottom. emerge of the...If you want to get a full essay, order it on our website: BestEssayCheap.com
