| 中文摘要: |
| 根据扎村金矿区域成矿地质背景、矿区地质特征,结合扎村金矿床与莲花山富碱岩体在成矿时代、蚀变特征、岩性等方面的对比,以及扎村金矿区同位素数据分析,认为莲花山石英二长斑岩岩浆热液系统不仅提供了金矿的成矿物质和流体来源,也是驱动成矿流体循环的主要热源;从成矿系统的角度探讨了扎村金矿区的主要成矿要素,提出扎村金矿属浅成中-低温热液矿床,并构建了成矿系统模型,总结了找矿标志,预测有利的找矿地段为阿皮洒都、查雷村—五里巷、红花园及扎村金矿—大莲花山一带。 |
| 英文摘要: |
| According to the metallogenic background, geology of Zhacun Au property and its isotopic analysis and comparison of the ore-forming times, alterations and lithology of the property and alkali-rich intrusive body we consider that the hydrothermal fluid system of quartz monozite porphyry is not only the source of ore materials and the fluid itself but also the main heat and motive force of the fluid circulation. From aspect of the metallogenic system the ore-forming factors are discussed, a proposal is made that is the epi-mesothermal Au deposit may be here, model of the system is built, prospecting marks and targets pointed out, such as Apisadu, Chaleicun-Wulixiang, Honghuayuan and and Dalianhuashan areas. |
