| 中文摘要: |
| 东乡铜矿位于江西省东乡县,是一个以铜为主的中型铜(钨)多金属矿床,为赣东北有色金属成矿带的一部分.结合东乡铜矿区域成矿地质条件,运用有关区域成矿学和多因复成矿床的成矿理论,通过矿床地质学、成矿构造学、矿物岩石学等方面的综合研究,阐明了东乡铜矿的矿区地质特征及成矿规律,建立起了该区铜矿床矿床成因模式与找矿模型,进行了找矿预测,对矿区找矿工作实践具有重要指导意义.研究表明,其成矿物质部分来源于基底岩系;石炭系地层主要作为赋矿岩石,同时也可以提供部分成矿物质;区内岩浆活动和深层卤水的运移更是使“初始矿源层”中的成矿物质得到进一步交代、改造和富集的主要原因;矿体的最后定位与后期构造运动的改造作用有关.其矿床成因主要为以晚古生代同生喷流沉积成矿作用为主体,并伴有其它成矿作用为特点的多因复成矿床. |
| 英文摘要: |
| Dongxiang copper deposit is located in Dongxiang County of Jiangxi Province, which is a medium-size copper (tungsten) ore polymetallic deposit and mainly composed by copper ore. It is a part of the non-ferrous metal metallogenic belt. Integrating with the geological conditions of ore formation of Dongxiang copper deposit and applying the metallogenic theories related to the regional metallogeny and the polygenetic compound deposit, it had clarified the geological features and the metallogenic regularities of Dongxiang copper deposit, the metallogenic and ore-prospecting model were established that of the copper deposit in this area and the ore-prospecting was forecested through the comprehensive researches on the mineral petrology, metallotectonic and mineral deposit, which is significant for the instruction of the ore-prospecting practice. The researches show that the ore-forming materials are derived from the fundamental series; the carboniferous strata is mainly as the rich ore rock and also provide a part of metallogenic material; the magma movement in this area and the migration of deep brine are the main causes for the further replacement, transformation and enrichment of the metallogenic materials in the initial bed; the final positioning of the ore body is related to the transformation of the later structure movement. The main reason of the ore formation is the syngenetic exhalation sedimentation in the late Paleozoic era with the polygenetic compound deposit which is characterized by other mineralizations. |
