Book Description
The Tanco pegmatite at Bernic Lake, Manitoba, Canada is a highly fractionated rare-element class, LCT family pegmatite with 9 internal zones and is one of the largest complex internally zoned pegmatites in the world. The outer zones of the pegmatite are generally concentric, while the shape of the inner zones, based on underground workings and drill core observations, are very irregular and complex. Tanco presents a unique opportunity to calculate the bulk composition of a pegmatite which, unlike previous works on other pegmatites, does not need to consider structural deformation and/or erosion to reconstruct the original size and shape. Tanco is essentially an undeformed blind pegmatite, with only minimal exposure through erosion at the bottom of Bernic Lake. Almost no reconstructive interpretation is required as th amount of eroded material is negligible and does not affect the over-all bulk composition calculations. Given the available information from the drill core logs and underground workings on theTanco pegmatite, it was possible to create the first 3D computer representation of a pegmatite.

Book Description
Rare Earth Elements (REE) as well as tantalum and niobium are of tremendous importance because of their specific high-technology applications. The contributions gathered in this volume give an up-to-date survey on the mineralogy, primary ore deposits, prospecting, processing and applications of REE, Ta, and Nd, making this volume a useful handbook for practitioners and students. Finally, the comprehensive coverage of the fundamental aspects, especially as regards REE as tracers of geological phenomena, will prove extremely helpful.
Archean Rare-Metal Pegmatites in Zimbabwe and Western Australia

Book Description
Lithium-cesium-tantalum (LCT) pegmatites are important resources for rare metals. For Cs, only the LCT pegmatites with the zeolite group mineral pollucite at Bikita (Zimbabwe Craton) and Tanco (Superior Province Craton) are of commercial importance. Common characteristics of world-class LCT pegmatite deposits include their Meso- to Neoarchean age and geological setting within greenstone belt lithologies on Archean Cratons. This study presents the first coherent and comparative scientific investigation of five major LCT pegmatite systems from the Yilgarn, Pilbara and Zimbabwe Craton. For the evaluation of their Cs potential and of the genetic concepts of pollucite formation, the pegmatites from Wodgina, Londonderry, Mount Deans and Cattlin Creek were compared to the Bikita pollucite mineralization. The integration of the new data (e.g., geochronological and radiogenic isotope data) into the complex geological framework: 1) enhances our knowledge of the formation of LCT pegmatite systems, and 2) will contribute to the further exploration of additional world-class LCT pegmatite deposits, which 3) may host massive pollucite mineralisations.
