WebWhat happens when granite is weathered? (from the site of Pamela Gore, Georgia Perimeter College) First, unweathered granite contains these minerals: o Na Plagioclase feldspar o K feldspar o Quartz o Lesser amounts of biotite, amphibole, or muscovite The feldspars will undergo hydrolysis to form kaolinite (clay) and Na and K ions The Na and K … WebCrystal structure. Sanidine and orthoclase are monoclinic or nearly so; the plagioclase feldspars are triclinic.All, however, have the same fundamental structure: it consists of a continuous, negatively charged, three-dimensional framework that is made up of corner-sharing SiO 4 and AlO 4 tetrahedrons (each tetrahedron consists of a central silicon or …

WebOrthoclase is the main k-spar of granites and syenites that cooled moderately quickly. Sanidine and anorthoclase are common constituents in extrusive igneous rocks such as rhyolites, where the rock cooled quickly. Optical properties and x-ray techniques are the only sure ways to distinguish orthoclase from sanidine, microcline and anorthoclase.
