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 situation was formed was the Leatherwood Granite dictated freighter Food Lion. beneficial from outward appearance at that household were obvious weathering and fractures with filled in sediments. Also the surface of these disputations was close together(p) and had a phaneritic texture payable to the moderate but visual 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 member of the site. These fractures show there were volcanic activity melting from the nates therefore cooled down allowing unlike sediments fill in the cracks then molding in rear with the igneous structure showing the sequen ce of events. Second obvious observation was the two disparate origins of the rocks, mainly mafic but there was a small office that was felsic. Looking at the felsic rock closer I truism 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 bunghole Food Lion, we went to the Fork Mt. Gneiss. This site was large and had many sundry(a) regions showing how it heated from the loafer creating the foliation lines and xenoliths. The very noted foliation and the red gar nets located at the bottom of the site impli! ed that the rocks were metamorphic . These attributes show that the rock on the bottom had lead extremely hot and melted. The metamorphism is regional. The two rocks varied because of the temperature during the creation of the rocks. The vellicate was foliated, the minerals lined up from pressure and enough heat to watch it layer and not melt. The bottom showed that the heat source was from the bottom. come on of the...If you want to get a full essay, order it on our website: BestEssayCheap.com
