rocks, to such an extent that the classification of a number of rocks is based upon feldspar content Chemically, the feldspars are silicates of aluminium, containing sodium, potassium, iron, calcium, or barium or combinations of these elements The crystalline structure of feldspars consists of an infinite network of SiO 2 and AlO 4 tetrahedra
4) Since the late Pliocene, the style and composition of volcanism in the Trans-Mexican Volcanic Belt became more diverse In several areas, volumetrically dominant calc-alkaline rocks are associated with modest volumes of intraplate-like lavas or other potassium rich rocks, accompanied by Quaternary rhyolitic peralkaline rocks
Shoshonite is a type of igneous rockMore specifically, it is a potassium-rich variety of basaltic trachyandesite, composed of olivine, augite and plagioclase phenocrysts in a groundmass with calcic plagioclase and sanidine and some dark-colored volcanic glassShoshonite gives its name to the shoshonite series and grades into absarokite with the loss of plagioclase phenocrysts and into .

Cooling of the magma body causes crystals of olivine, pyroxene, and calcium-rich plagioclase to form and settle out thus leaving the remaining melt rich with silica Define Bowen's reaction seri Shows the sequence in which minerals crystallize from magma (Olivine, Pyroxene and Plagioclase Feldspar, Potassium Feldspar and Muscovite, and .
Olivine is found in many different rocks: Basalts and "peridotitic" (peridot-rich) rocks; rocks that contain little quartz; Mantle rocks; the mantle is composed mostly of olivine "dunite" is a rock made almost entirely of olivine; Volcanic rocks, like those found at Kilbourne Hole; Xenoliths (lumps of rock ripped up from a source area and .
