Bulk Chemical Composition Of Basalt Versus Granite

Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks.

Bulk chemical composition of basalt versus granite.

Granite is a felsic rock meaning that it has a high silicon content. Basalt is basic and contains a substantial amount of olivine whereas granite is. Basalt as a mafic rock contains more calcium oxide manganese oxide and iron compounds than granite. Granite is an intrusive igneous rock with a felsic composition.

Chemical and isotopic systematics of oceanic basalts. 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. As two rocks are not same it s fun to compare them. Sio 2 49 97 tio 2 1 87 al 2 o 3 15 99. To this end we present.

Furthermore many of the continental rock formations are. 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. Granite is lighter in color than basalt. The color of the rocks is dependent on the mineral composition of the rock.

Granite makes up the cores of continents and much of the bulk of major mountain ranges around the world. 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.
