Matthew R. Sanders,John A. Pickeringo 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

Carolyn L. Webster-Stratton Ph.D., FAANte, 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
