Bulk Chemical Composition Of Basalt Versus Granite

Furthermore many of the continental rock formations are.

Bulk chemical composition of basalt versus granite.

To this end we present. Implications for mantle composition and processes january 1989 geological society london special publications 42 1. It is mostly made out of quartz mica and feldspar. As the chemical composition of earth s mantle plays a critical role in a number of geochemical and geophysical models it is important to establish a composition model with its uncertainty firmly quantified.

Granite for example can have a quartz content anywhere between 20 and 60. Porosity and density this range of densities can also be attributed to a rock s porosity the amount of open space between mineral grains. Granite vs basalt information earth s outer layer is covered by rocks and these rocks have different physical and chemical properties. You can also know more about granite and basalt reserves.

Chemical and isotopic systematics of oceanic basalts. Granite is an intrusive igneous rock with a felsic composition. As two rocks are not same it s fun to compare them. 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.

Basalt as a mafic rock contains more calcium oxide manganese oxide and iron compounds than granite. Granite is lighter in color than basalt. Composition average chemical composition of basalt determined by 3594 chemical analyses of basaltic rocks 2 numbers are mass percents recalculated volatile free to total 100. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks.

Granite is a felsic rock meaning that it has a high silicon content. Sio 2 49 97 tio 2 1 87 al 2 o 3 15 99. The color of the rocks is dependent on the mineral composition of the rock.
