In LCT pegmatite systems, fractional crystallisation is interpreted to cause economic enrichment of Cs, Li, Rb, Be, Nb, Ta and Sn. Certain elements are enriched within the crystal cumulus, when the mineral/melt distribution coefficients D are >1 (compatible elements) and thus their concentration is depleted within the remaining melt.
This paper reviews the main controls of LCT pegmatite genesis relevant to mineral exploration programs and presents a workflow of grassroots exploration techniques, supported by examples from
The common presence of large, wellpreserved fluid and melt inclusions in pegmatite minerals has led to a huge body of dominantly Russian literature. General aspects of pegmatite formation have been discussed in London (2008), whereas a review on the salient features of melt and fluid inclusions can be found in Thomas et al. (2006b).

The name pegmatite has nothing to do with the mineral composition of the rock, but rather describes a rock’s physical structure. To be called a pegmatite, the rock should be composed almost entirely of
The most distinguishing feature of pegmatites is the presence of extremely large sized crystals (e.g. gemquality beryl measuring 55 x 18 x 16 cm in size and weighting 22 kg was extracted from Volyn

Major minerals identified in the pegmatite bodies are quartz, plagioclase and micas. Albites (An0.1–0.8; Ab98.7–99.6 and Or0.3–0.5) are found as the dominantplagioclase minerals in the pegmatites from the Gatumba area. Albites are precursors to kaolinites, and the albitisation and kaolinisation processes altered the primary emplaced

Abstract. The Kafubu emerald deposits occur within rocks of the Muva Supergroup which form the youngest part of preKatangan basement immediately southwest of the well known Copperbelt of Zambia. Within the Muva Supergroup are persistent bands of talc—chlorite—amphibole (tremolite/actinolite) magnetite schist, which are intruded
The Chakabeishan (CKBS) deposit is the first pegmatitetype LiBe deposit discovered in the eastern North Qaidam Tectonic Belt (NQTB) of Tibetan Plateau. The correct understanding of its petrogenesis and the precise determination of its formation age are of great significance for further regional prospecting and the discovery of new
The presence of significant caesium concentrations of more than 40ppm from soils around the pegmatitebearing Shabaash lepidolite was demonstrated by the satellite bodies at the Arcadia mine. The identified caesium exists within pollucite, a rare caesium mineral of high value that forms in pegmatite structures of extremely
The mineral pollucite is the main source of the metal cesium. Other elements that may be sourced from pegmatite include tantalum, niobium, bismuth, molybdenum, tin, tungsten, and the rare

Pegmatites may be composed of a variety of minerals. Terms such as granite pegmatite, gabbro pegmatite, syenite pegmatite, or names with any other plutonic rock type as prefix are used. Compositions in the range from granodiorite to granite are common. Large crystals of quartz, potassium feldspar, sodium rich plagioclase, and
