| 中文摘要: |
| 扎拉格阿木铜多金属矿床位于大兴安岭中南段西坡的南端,是在1∶5万化探异常的基础上通过进行矿产预查发现的,经普查铜金属资源量已达中型规模。矿体赋存于二叠系哲斯组砂板岩和二叠纪花岗闪长岩的外接触带的浅变质砂板岩夹少量火山岩中,主成矿元素为铜,伴生银和少量铅锌,矿体呈脉状产出,矿体规模较大。通过对赋矿围岩岩性、产状及矿石结构和构造等方面的初步研究认为,矿床成因为沉积和构造热液(或次火山热液)叠加型矿床。该矿的发现是近几年在内蒙古自治区境内铜矿找矿方面的重要新突破。 |
| 英文摘要: |
| The Zalageamu copper poly-metallogenic deposit located in the southern part of western slope in middle -south section of Daxinanling range belt, was discovered through reconnaissance investigation on the basis of 1∶50 000 geochemical sampling programme. The copper metal tonnage can reach middle size according to general exploration achievement. The orebodies mainly occur in the low grade metamorphic sand slate and minor in volcanic rocks which are nearby the outlier contact zone between Permian low metamorphic rocks of Zesi group and Permian granite intrusion in the deposit area. The main metallogenic element is copper with minorsilver, lead and zinc elements. Orebodies distribute in form of veins and large scale. Through the preliminary study on the lithology of host rocks, ore texture and structure, the results show that the deposit belongs to sedimentary and structural hydrothermal (or subvolcanic hydrothermal) superposition type deposit. The discovery of the Zalageamu copper polymetallic deposit is the great exploration breakthrough for the copper deposit in Inner Mongolia in recently years. The implications for its discovery are very useful for exploring similar copper deposits in Inner Mongolia. |
