| 中文摘要: |
| 穆家庄铜矿床为一中型铜矿床,位于南秦岭礼县—柞水海西褶皱带东段,柞水—山阳泥盆纪热水沉积盆地菱铁多金属成矿带中部,矿体赋存于主要含矿层位中泥盆统大西沟组中,岩性为一套浅变质海相细碎屑岩—碳酸盐岩。该矿床为典型的沉积—改造型矿床,其形成经历了预富集、再富集两个阶段,为秦岭造山带海西期和印支—燕山期构造活动的产物。通过对矿床的地质、地球化学、地球物理等特征的综合研究分析,认为穆家庄铜矿床深部及外围找矿潜力巨大,在柞水—山阳矿集区有望实现大型铜矿床的找矿突破。 |
| 英文摘要: |
| The Mujiazhuang copper deposit is a medium-sized deposit which is located in the eastern Lixian-Zhashui Hercynian folding belt, and central part of the siderite polymetallic metallogenic belt of Zhashui-Shanyang Devonian hot water sedimentary basin in the southern Qinling orogenic belt. The main host strata is Middle Devonian Daxigou group which consist of a set of low metamorphic marine clastic and carbonate rocks. This deposit is a typical sedimentary-reformed deposit, and its formation has experienced two stages, i.e., pre-enrichment and re-enrichment stage, the deposit formation resulted from the Hercynian and Indosinian-Yanshan tectonic activity of Qinling orogenic belt. Based on the integrated study on geological, geochemical, geophysical and other features of the deposit, it is believed that there is a great prospecting potential in the depth and surrounding area of Mujiazhuang copper deposit area. It is possible for finding a large-sized copper deposit and achieving significant exploration breakthrough in the Zhashui-Shanyang mineralization region. |
