| 摘 要： | 焦家金矿床是著名的构造破碎蚀变岩型金矿床，通过物化探研究，对深部成矿远景进行预测并布置了钻探工程，大致查明了矿床深部破碎蚀变带地质特征及含矿性；基本探明了矿体的规模，形态，产状及赋存部位，矿石的类型和结构构造等特征，并合理地圈定了矿体，以深部原生晕建立了深部化探异常模式，指出了深部矿体矿头和近矿指示元素组合特点，从而为深部是否继续开展普查提供了依据。通过钻探工程验证，矿体及构造带的位置与物探结果比较吻合，说明本区物探方法寻找隐伏矿体有较好的效果。

| Abstract: | Jiaojia gold deposit is the altered rock type deposit hosted in cataclastic zone. Geophysical and geochemical technologies were engaged in ore prediction at depth. According to the results were arranged drill holes that basically make clear of geological feature and ore-bearing property of cataclasitic alteration rock, size, morphology, occurrence and location of ore bodies and ore textures and ore types. And the ore bodies are located proprely. Characteristics of head and near ore element associations of deep ore bodies are drawn from geochemical anomly model defined by primary geochemical halo at depth. Based on the data further deep exploration is suggested. Coincidence of the drilling and geophysical and geochemical exploration prove that the latter is an effective tool to search for blind ore bodies. |
