The Li-bearing pegmatites of the Pampean Pegmatite Province (PPP) occur in a rare-element pegmatite belt developed mainly Lower Paleozoic age on southwestern margin Gondwana. show Li, Rb, Nb ≤ Ta, Be, P, B, Bi enrichment, and belong to Li-Cs-Ta (LCT) petrogenetic family, Rare-Element-Li (REL-Li) subclass; most them are complex type spodumene subtype, some albite-spodumene type, few petalite sub...

Abstract The GREENPEG project, which is funded by the European Commission Horizon 2020 ‘Climate action, environment, resource efficiency and raw materials’ programme, aims to develop multimethod exploration toolsets for identification of European, buried, small-scale (0.01–5 million m 3 ) pegmatite ore deposits Nb–Y–F (NYF) Li–Cs–Ta (LCT) chemical types. project being coordinated Natural Histor...

fro11 1 pegmatite in Cardiff township, Haliburton County, Ontario. Found as dark reddish brown to brownish black anhedral masses. Hardneis B$, specific gravity 8,08. Metamict; isotropic with n near 1.630. when the mineral is heated at 925" i the n increases to about 1.640 and the specific gravity to 8.20. At high temperatures the mineral decomposes before it recrystallizes and r-ray difiraction...

ABSTRACT A previously undescribed small lenticular (~5 × 5 m) pegmatite, located near Wellington Lake in the NW part of 1.08 Ga ‘A-type’ (anorogenic) ferroan Pikes Peak granite batholith, ~15 km SW South Platte pegmatite district central Colorado, is concentrically zoned around a mostly monomineralic quartz core with interconnected miarolitic cavities. Major constituents are quartz, perthitic m...
