Geological Features and Genesis of the Jinchang Cu-Au Deposits in Heilongjiang Province
摘要
Abstract
The Jinchang Cu-Au deposit, geographically located in Northeast China and tectonically in the easternmost part of the Xingmeng orogenetic belt, is a super-large gold deposit with a mineralization age between 110 ~ 130Ma Its gold ore types are mainly breccia and vein types. The typical breccia-type ore body No. J-l occurs in the breccia pipe No. I in Qiongbangzigou, which displays as a cryptoexplosion breccia pipe with entire pipe minerali-zation and clear boundaries with wall rocks. The breccia-type ore bodies often appear in clusters and groups, and are equally spaced in an east-west trend. The vein-type ore bodies include ring-like and radiated ore bodies; the vein groups of II and 18 are typical ring-like orebodies; and the vein group III is of a typical radiation pattern. As a whole ring-like ore bodies are distributed as a layered or vein type on the surface and an arc shape on profile, the vein group II is located in the upper part of the magma dome, and the vein group 18 in the lower part. These ring-like orebodies exhibit mineralization zoning outward. The Jinchang gold deposit is situated in the margin of the continental arc setting produced by Pacific plate subduction, and its fluids and ore-forming materials result from the deep source magma All breccia type and magma-dome type ore bodies show mineralization characteristics of porphyry deposits.关键词
