| 中文摘要: |
| 雄黄岩金矿床位于黔西南灰家堡矿田东段,矿床受灰家堡背斜控制,矿床位于灰家堡背斜东段枢纽产状由缓变陡地段,主要矿体赋存于中上二叠统茅口组与龙潭组岩溶不整合面构造蚀变体中,矿体分布于背斜核部800 m,矿体规模大；其次赋存于龙潭组中上部不纯碳酸盐岩中,矿体分布于背斜核部300500 m。构造蚀变体普遍具金矿化,能否形成工业矿体受卷入地层厚度、岩性组合、蚀变强弱及古岩溶地貌等因素控制。通过对该矿床地质特征的研究,特别是构造蚀变体矿化研究和深部地球探测,认为在该区沿灰家堡背斜轴线向东延伸段、两翼构造蚀变体及北翼F101断层带中仍有矿体存在,具有较好的找矿远景。 |
| 英文摘要: |
| Xionghuangyan gold deposit situated in the east of Huijiabao ore field, the deposit is controlled by Huijiabao anticline and located in the east Huijiabao anticline where the occurrence becomes steep. The major orebody occurred in the uncomfortable structural alteration rock of Maokou formation and Longtan formation in middle-upper Permian Strata, the orebody distributed 800m depth of the core anticline and the scale is huge, some occurred in the impure carbonate rock of middle-upper Longtan formation and distributed 300-500m depth of the core anticline. The structural alteration rock mineralized universally, whether it can be industrial orebody is controlled by strata thickness, lithology composition, alteration degree and paleokarst landform. By the study, especially the mineralization of structural alteration rock and deep geotection, it’s thought there are more orebody existed in the east extension, both sides structural alteration rock and north fault along Huijiabao anticline, so it has good prospecting. |
