2021年12月5日 Lithium Trace elements LAICPMS 1 Introduction Quartz comprises 20 to 40% of granitic pegmatites, typically displaying large crystal dimensions, making it a major mineral constituent of these rocks and an important economic resourcePegmatites represent the last and most hydrous portion of a magma to crystallize, rich in volatiles like F, B, P, etc and hence contain high concentrations of minerals present only in trace amounts in normal granitic rocks Arguably, these rocks can be considered to be as much hydrothermal as igneous in origin Unique Identifiers Hide Mindat ID:Pegmatite: Mineral information, data and localities2021年3月6日 Pegmatites define as a case of highly evolved granitic melts which result of protracted fractional crystallization [ 41] and are of scientific interest as they display complex and diverse textures, mineralogy, structures, and petrogenetic relationships, with evolved geochemical signatures, which have challenged petrologists in terms of the origiPanAfrican rare metals bearing pegmatites in Wadi Ghadir, South2006年8月22日 Content may be subject to copyright Petrogenesis of rareelement pegmatites in the Olary Block, South Australia, part 1 Mineralogy and chemical evolution Birch, W D and D A Henry 1997 GemPegmatites A gem quality berylbearing pegmatite in the Wiborgite Rapakivi granite batholith A glance into the 163Ga old Luumäki pegmatite system Some of the most intriguing rock formations on planet earth are pegmatites with their often exotic assemblage of minerals in various sizes, shapes and colorsPegmatites Geochemistry and Petrology University of Helsinki(PDF) Australian Pegmatite Minerals ResearchGate
