Basalt And Granite Samples

In the second region 400 to 1000 k for basalt and 450 to.
Basalt and granite samples. Also gabbro has no alkali feldspar only plagioclase feldspar with a high calcium content. Lab 6 igneous rock samples red granite rhyolite diorite gabbro gray granite obsidian andesite basalt rhyolite tuff pumice lab 6 igneous rock samples red granite rhyolite diorite gabbro gray granite obsidian andesite basalt rhyolite tuff pumice lab exercise 2. The key difference between basalt and granite is that basalt is mostly occurring on ocean floors while granite is in the crust of the earth in all continents. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks.
In the first region rt to 400 k for basalt and rt 450 k for granite samples the electrical resistivity exhibits a slight decrease. The evaporation increases salinity by increasing na and cl and thus tds. Basaltic crust is dark and thin and heavy while granite is light and accumulates into continent sized rafts which bob about like corks in this sea of basalt. Granite is the principal component of the continental crust while basalt is the principal component of the oceanic crust.
Basalt and granite are two types of igneous rocks. Igneous rocks are formed through the cooling and solidification of magma or lava and they may form with or without crystallization. As it turns out most of the ocean floor is basalt and most of the continents are granite. Unlike granite gabbro is low in silica and has no quartz.
Rest 35 of basaltic samples is evaporation dominance. In the second region 400 to 1000 k for basalt and 450 to 1000 k for granite samples the electrical resistivity exhibit a rapid decrease with the increase of temperature. Magma volcanism and igneous rocks every igneous rock has a story to tell that geologists can unravel by considering the rock s. Igneous rock specimens in packs of 10 or as hand samples.
Gabbro is a dark colored igneous rock that is considered to be the plutonic equivalent of basalt.
