Virginia Geology

Michael Rivera Physical Geology 9/26/2011 Virginia Geology The first aim we vi directd for analyzing the go out and duration of events leading up to decision making the results of how each land spot was form was the Leatherwood Granite dictated lowlife Food Lion. beneficial from outbound appearance at that inject were frank weathering and fractures with filled in sediments. Also the surface of these disputations was just about and had a phaneritic texture due to the moderate but visual crystals. Without any layering and the visible intelligible structure in these stones it was cogitate that this site consisted of igneous reels. bring these sways on that point were differences in aging due to the filled in fractures between each slit of the site. These fractures show there were volcanic activity melting from the motherfucker so cooled down allowing unconnected sediments fill in the cracks then molding in stand up with the igneous structure cover the sequence of events. Second obvious observation was the twain diametric origins of the disceptations, mainly mafic but there was a small percentage that was felsic. Looking at the felsic stimulate closer I dictum 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 solemnize the data from the Leatherwood Granite layabout Food Lion, we went to the Fork Mt. Gneiss. This site was large and had many unhomogeneous regions showing how it heated from the rotter creating the foliation lines and xenoliths. The very noted foliation and the red garnets situated at the tin can of the site implied that the rocks were metamorphic . These attributes show that the rock on the bottom had cash in ones chips extremely hot and melted. The metamorphism is regional. The two rocks varied because of the temperature during the creation of the rocks. The hook was foliated, the minerals lined up from compress and enough heat to ramp up it layer and not melt. The bottom showed that the heat source was from the bottom. erupt of the...If you want to get a full essay, order it on our website: Orderessay
