| 中文摘要: |
| 郝家河铜矿位于滇中盆地砂岩成矿带上,属沉积砂岩型铜矿。河湖交替相是有利于沉积成矿的环境,构造控制矿带的展布,马头山组特别是其中下部郝家河段是主要的含矿层位,矿化发育于浅紫交互带,主要工业矿体产于紧靠浅紫界线的浅色砂岩中,容矿岩石为灰色砂岩、含砾砂岩和页岩,其中以渗透性好的砂岩为主,浅紫交互简单、下紫上浅、界线清楚稳定、产状缓则矿化好,矿物分带指示矿体存在位置和矿体富厚中心。根据矿体赋存规律,预测找矿靶区、指导找矿工作,通过实施地质找矿,取得了较好的效果。 |

| Abstract:Hao Jiahe Coppermine is on the metallogenic belt of Dianzhong basin, which belongs to Sedimentary gritstone-type coppermine. Alternating phase of river and lake is in favor of the surroundings of depositional mineralization and spread of structural control of ore belt. Formation of Ma Toushan group, especially Hao Jiahe section in bottom of Ma Toushan group, its mineralization developed in grey violet mutual contact zone, and main industrial ore body deposit was produced in pale gritstones which snuggle up to grey violet boundary .The components of the host rocks include grey gritstone, pebbly gritstone and shale, and gritstone with good permeability is the main component part of host rocks. Interaction of main industrial ore body between grey violet and violet are simple, and violet gritstones are under the grey violet gritstones, and the boundary is clear and stable. If the inclination of rock formation slopes slowly, mineralization developed well. Zonations of mineralization indicate the position and rich-thick position of ore bodies. According to the hosting rule of ore body, it can help us predicting prospecting target area, and directing prospecting work. Good results have been achieved through conducting of geological prospecting. |
