Correlation of Sillimanite Kaliophilite Minerals, TOC

Sillimanite mineral is a brittle mineral which is a metamorphic mineral product that generally comes from clay, along with the increase in pressure and high temperature (600˚C 900˚C) with a burial depth of about 5 6 km, and is very influential on hydrocarbon generationSillimanite minerals comprising sillimanite, andalusite and kyanite are naturally occurring anhydrous aluminiumsilicate poly morphs with the chemical formula Al2SiO5 They are all com mon rockforming minerals differing somewhat in crystallo graphic characteristics and thereby in physical propertiesUtilisation of sillimanite minerals, their geology, and Sillimanite Group Minerals These minerals include the Al 2 SiO 5 polymorphs sillimanite, kyanite, and andalusite, all theoretically with 6292 wt% Al2 O 3 Although sillimanite is known to occur in many highgrade gneisses and in some quartzites, no potential deposits have yet been found in FinlandSillimanite an overview ScienceDirect Topicssillimanite minerals (anadlusite, kyanite, and sillimanite) are described Their P–Tdiagram is discussed The structural differences among the three are reviewed, emphasizing the coordination of the Al3+cations that link the double octahedral chains within the structuresChapter 3 The Sillimanite Minerals: Andalusite, Kyanite Bowen G T (1824) Description and analysis of sillimanite, a new mineral, American Journal of Science and Arts, 8, 113118 [view file] Bowen G T (1824) Description and analysis of sillimanite, a new mineral from Saybrook, in Connecticut, US, The Annals of Philosophy, 8, 315316 [view file]Sillimanite R RRUFF Database: Raman, Xray
