| 中文摘要: |
| 河南省卢氏县橡子庙沟铁矿床地处北秦岭加里东褶皱系多金属成矿带,通过地表工程和中深部钻探工程,控制主矿体9条矿脉。矿体多呈似层状产出,矿体与围岩产状基本一致,层控作用明显。与成矿关系密切的为二郎坪群火神庙组地层,在变细碧岩与大理岩的接触带是最有利的成矿部位,矿区内断裂构造的多期次活动对矿液的运移和富集起到了重要作用,汤河岩体及张家庄岩体为本区多金属成矿提供了丰富的成矿物质和成矿热液。结合区域地质背景、矿床地质特征及区内矿物岩石学特征,认为矿床成因与海相火山—侵入活动有关,为海相火山岩型铁矿床。 |
| 英文摘要: |
| Lushi Xiangzimiaogou iron deposit is located in the Caledonian fold system of Northern Qinlin Area. Nine ore veins of the main ore body is delineated through surface engineering and medium-deep drilling engineerings. Most of the ore bodies are stratoid in form and have a similar occurance to wall rock, showing an obvious characteristic of layer control. The most favorable mineralization parts are the contacting zones between metamorphised spilite and marble which are both belong to the Huoshenmiao formation of Erlangping group. This formation has a close relation to mineralization. The multi-phases activities in the deposit area plays an important role in the movement and concentration of ore liquids. Tanghe rock mass and Zhangjiazhuang rock mass offers plenty of the mineralization substance and hydrothermal solution for polymetallic mineralization in this area. Considering the regional geological background, geological characteristics of the deposit and characteristics of minerals and rocks, it is concluded that this is a marine volcanic type iron deposit, which is believed that the origin of the deposit is related to Marine volcanic-invasive activities. |
