| 中文摘要: |
| 王家坪金矿床位于山阳—凤镇大断裂和镇安—板岩镇大断裂之间,柞水—山阳多金属矿集区东端,区域构造线呈东西向展布,矿区主要出露上泥盆统星红铺组地层,北侧发育一条断裂—酸性岩浆活动带,赋矿围岩为不纯的灰岩。通过对矿床地质特征的研究,认为金矿成因类型为低温热液矿床,为一套低温元素组合,矿石类型为微细浸染型金矿石。初步总结了该矿床的成矿规律,建立了找矿标志,为下一步该类型金矿床的找矿提供了借鉴依据。 |
| 英文摘要: |
| The Wangjiaping gold deposit occurred between Shanyang-fengzhen fault and Zhenan-Banyanzhen fault, is located in the eastern part of Zhashui-Shanyang polymetallic ore concentration area. The general direction of regional structural attitude is E-W strike. The strata outcropped in the deposit area mainly is late Devonian Xinghongpu formation, and the host rock is impure limestone. In addition there is a fault-felsic magmatic belt in the northern area. On the basis of detailed geological survey and deposit geology study, the deposit genesis was defined as hydrothermal gold deposit with low temperature, known as carlin type deposit. The ore type is mainly fine disseminated ore. Finally, the ore formation characteristics were summarized and prospecting criteria were established, which provides a reference for next stage gold exploration in this area. |
