Abstract:On the basis of mineralization modes, basic metallogenic features, key ore-controlling indicators, relationship between mineralization and its ore-forming environment, the primary gold deposits in northern Xinjiang can be divided into seven types, namely epithermal gold deposits, altered rock type gold deposits in the ductile shear zone, micro-fine-g rained dissemination gold deposits, supergene and structural-altered rock type gold deposits, metamorphic hydrothermal type gold deposits, auriferous quartz vein type deposits and copper gold assocrated deposits. By means of analysing and comparing these typical gold deposits in such aspects as REE partitioning patterns, trace element content and their partitioning patterns in gold ores, sulfur and lead isotopic com position and com position of quartz fluid inclusions, the authors deal with their metallogenic geochemical characteristics. In the light of their metallogenic geochemical features and basic ore-forming background, the authors generalize these gold deposits into four important mineralization series, viz. low-temperature and supergene gold series formed in some lateral districts beside large fractures in the island arc, gold series hosted in some ductile shear zones related to dynamic and metamorphic environment, middle-high temperature and middle-hypogene gold series formed in some orogenic belts, and copper gold associated series formed in Late Paleozoic marine volcanics. The authors also consider that a large-size gold deposit is often cha racterized by some special preferential mineralization conditions, and metamorphic hydrothermal type gold deposits have some specific mineralization features.
