【摘要】 新疆石英滩(西滩)金矿,前人多认为是浅成低温热液型矿床,近期在该区构造与成矿关系、矿田内东北夼、黄泥坡矿点原生晕指示元素分带序列和叠加晕研究中,发现了石英滩矿区、东北夼、黄泥坡等矿点地下不同深度均存在隐伏矿体,而三个矿区(点)的空间位置恰又与矿田内一近似椭圆的古火山机构同位,且三矿区(点)具有极其相似的地质构造、成岩(脉)成矿和原生晕特征,石英滩金矿区发现有古火山热液通道。这些控矿构造和原生晕特征反映了该金矿田成矿的特殊性,对进一步寻找和预测该区相类似的隐伏矿床(体)具有重要启示。更多还原

【Abstract】 Shiyingtan(Xitan) gold deposit of Xinjiang was considered as an epithermal deposit by most predecessors.Recently studies on relations between structure and mineralization,zoning sequences of the primary holes, and superimposition holes at Dongbeikuang and Huangnipo spots show that there exist blinding ore bodies at different depth in these three deposit and spots.Spatial locations of the deposit and spots are sited in an approximately elliptical paleo-volcanic apparatus with extremely similar characteristics of geological structure,rock-forming,mineral-forming and primary holes.The paleo-volcanic hydrothermal channel was found in the Shiyingtan gold deposit.These ore-controlling structures and primary holes reflect veining specialty,and have essential enlightenment for further exploiting and predicting similar blinding ore deposits(or bodies) in the field.更多还原
