演绎

Geological Settings of Archean Rare-Metal Pegmatites,o the Southern Cross Terrane in the southeastern part of the craton. Two main contrasting models for the seven Archean geodynamic events (D0–D6) are discussed: modern-style plate tectonics with a westward directed subduction type scenario, or vertical crustal movements induced by constantly upwellin

Petrography and Mineralogy,te, spodumene and beryl. The samples were classified into 21 distinct mineral associations or pegmatite mineral zones. At Bikita, pollucite forms lens-like massive mineralisation with a crosscutting vein network of purple lepidolite, petalite, quartz and feldspar. Pollucite exhibits rather inhomogen

Geochronology of Archean LCT Pegmatites,e Neo-Archean pegmatites due to the widespread occurrence of these minerals as accessories in almost all samples. Furthermore, they are formed at a virtually constant level during pegmatite crystallisation from main crystallisation to late state hydrothermal overprint. The .Ar/.Ar ages cover a large
