中文摘要:
      陕西省凤太矿集区是南秦岭铅锌金多金属成矿带的重要组成部分,区内已发现并探明了数量众多的铅锌矿床。如今找矿工作已经转入到深部找矿阶段,运用“勘查区找矿预测理论与方法”进行典型矿床研究,建立典型矿床“三位一体”地质模型和找矿预测模型,对深部找矿工作有重要的意义。本文通过对区内铅硐山—东塘子铅锌矿床总结研究,论述了铅硐山—东塘子铅锌矿床地质特征,成矿地质体为深部隐伏岩体,成矿构造为背斜与断裂复合构造系统,成矿结构面为古道岭组灰岩与星红铺组千枚岩岩性接触界面(硅钙面),成矿时代为晚三叠世,矿床类型是层控岩浆热液型铅锌矿床,建立了典型矿床“三位一体”地质模型和找矿预测模型。
英文摘要:
      Fengtai ore concentration area in Shaanxi Province is an important part of the southern Qinling lead-zinc-gold polymetallic metallogenic belt, in which a large number of lead-zinc deposits have been discovered and proved. Now the prospecting work has shifted to the stage of deep prospecting. It is of great significance to use "prospecting prediction theory and method" to study typical ore deposits and establish "trinity" geological model and prospecting prediction model of typical ore deposits. In this paper, the geological characteristics of the Yidongshan-Dongtangzi lead-zinc deposit in the area are summarized and studied. The ore-forming geological body is a deep buried rock mass, the ore-forming structure is a composite tectonic system of anticlinal and fault, the ore-forming structural plane is the lithologic contact interface (silica-calcium plane) between the limestone of Gudaoling Formation and the lime-tite of Xinghongpu Formation, and the ore-forming age is late Triassic. The type of deposit is strata-controlled magmatic hydrothermal lead-zinc deposit, and the "trinity" geological model and prospecting prediction model of typical deposit are established.
