| 中文摘要: |
| 石人沟铁矿位于马兰峪—迁西铁矿成矿带上。区内出露的地层主要为太古宇迁西岩群马兰峪组一段,矿体赋存在该组地层中。2010—2015年5月实施河北省国土资源厅矿产勘查项目,“河北省遵化市石人沟铁矿带深部及外围找矿”项目取得重大找矿突破,共施工钻孔28个,钻孔见矿率达92.9%,新增铁矿资源量1.795亿t。矿石矿物主要为磁铁矿、假象赤铁矿；脉石矿物主要为石英,次为角闪石、斜长石及少量次生矿物黑云母。矿床成因类型为沉积变质型。该成矿带上的东沟—塔头寺、小王庄、胡庄子、铁山岭、西双城、大安乐庄、龙湾、烈马峪等与石人沟铁矿区具有相同的地质背景和航磁异常,矿床深部具有良好的找矿前景。 |
| 英文摘要: |
| The Shirengou iron deposit is located in the Malanyu-Qianxi iron deposit belt. The main outcropped strata is the first member of Malanyu formation of Qianxi group of Archean strata where the iron orebody occurs. By conducting the provincial exploration project of “Geological prospecting in the depth and its periphery areas of Shirengou iron deposit belt in Zunhua, Hebei” between the period of from 2010 to 2015, a great exploration breakthrough has been achieved.More than 90% of test drilling holed have intercepted the iron orebody, and the iron tonnae was increased by 179.5 Mt. The ore minerals are magnetite and martite, the main gangue mineral isquartz, minor amphiboles, plagioclaseand biotite. The deposit genesis is sedimentary metamorphic type. And same metallogenic setting and aeromagnetic anomaly exist in the following sites as followings Donggou, Tatousi, Xiaowangzhuang, huzhuangzi, Tielingshan, Xishaungcheng, Daanlezhuang, Longwan and Liemayu where indicate there are great prospecting potential. |
