An update study in micro-inclusions of emerald from worldwide significant deposits

Abstract

A conclusive study of inclusion in schist-type emeralds from some famous deposits in the world is introduced. The deposists includes Santa Terezinha, Socoto, Capoeirana, Itabira (Brazil), Mananrary (Madagascar), Transwaal (South Africa), Ural (Russia). The typical inclusions for emerald of these localities are quartz, mica, amphibole, fluid inclusions. Particular and unique features of inclusion could provide information of geographic orgirin. Itabira emerald is featurelized with the abundance of multi-phase inclusions containing two liquids, developed in well-formed negative crystals; more or less square, rectangular cavities. Santa Terezinha deposit is charactierized with pyrite inclusion which is not found in other deposits.
