摘要: 锡力诺尔金矿位于二连-贺根山断裂带偏南侧,为国土资源大调查中新发现的金矿点。本文在系统研究苏左旗-阿巴嘎旗地区成矿地质背景和成矿规律基础上,对锡力诺尔金矿点的地质特征和控矿因素进行了阐述,认为金矿化体主要赋存于二叠系上统林西组的细砂岩、砂砾岩的层间破碎带中,受控于北东向韧性剪切构造带和次级张性裂隙。通过锡力诺尔金矿点与外围金矿点的对比分析,初步认为锡力诺尔金矿体的成因类型为石英脉与蚀变岩复合型,矿体主体为低品位蚀变岩型,显示出较好的找矿前景。本文可为摸清该地区的金矿找矿思路和圈定金矿找矿靶区提供借鉴。Abstract: Located in the southern of Erlian-Hegenshan fracture, Xilinuoer gold deposit is newly found during im-plementation of land resources survey program. Based on the research of ore-forming geological background and ore-control regularity in Sunitzuo-Abaga Banner area, this paper mainly discuss geological characteristics and ore-control factors.Ore bodies mainly occur in the interlayer fracture zone between sandstone, glutenite interlayer fracture belt of Up Permian Linxi formation, controlled by northeast ductile shear zone and secondary tensile frac-ture. Contrasted with gold deposit(point) outside, genetic types of Xilinuoer gold deposits is quartz vein type and alteration rock complex type. The ore bodies are alteratde rocks with low grade, showing a good prospecting. This paper can provid a reference for the gold prospecting.
