| 中文摘要: |
| 巴彦哈尔敖包—昌特敖包地区位于内蒙古锡林郭勒盟苏尼特左旗,该区内探明大型金矿1处、小型金矿多处,如巴彦哈尔金矿、乌兰敖包金矿、干觉岭金矿、阿尔善特金矿、白音宝力道金矿、昌特敖包金矿等。通过对区内巴彦哈尔敖包金矿等典型矿床成矿规律的初步研究,结合近年来的勘查新进展发现,区内大多数金矿(化)体主要分布于温都尔庙群与加里东晚期、华力西期花岗岩、石英闪长岩接触部位,并受控于糜棱岩带,后又叠加了燕山期成矿活动,形成构造破碎蚀变岩型、石英脉型及次火山热液或斑岩型金矿。该地区金矿找矿潜力较大。由于温都尔庙群分布地段叠加有不同期次的岩浆岩及有利的构造,因此找到新的金矿床的可能性极大,应引起重视。 |
| 英文摘要: |
| Bayanhar Obo - Changte Obo area is located in Sunitezuoqi, Xilinguole Meng,Inner Mongolia.This area ascertained a large gold deposits and many small gold deposits, such as Bayanhar Obo gold deposit, Ulan Obo gold deposit, Ganjueling gold deposit, Ahlshante gold deposit,Baiyinbao Lidao gold deposit and Changte Obo gold deposit etc..Combine the preliminary study on metallogenic regularity of the typical deposit such as Bayanhar Obo gold deposits with the development of exploration in recent years, it is found that most of the gold deposits in this area mainly distribute in the contact zone between Wendell temple group and granite and quartz diorite of Caledonian and Variscan. These deposits are controlled by the mylonite belts and superimposed by later Yanshan mineralization activities which caused the formation of a variety of gold deposit of tectonic fractured alteration rock type, quartz vein type and subvolcanic hydrothermal and porphyry. This area have great potential for gold prospecting.It is probable to find new gold deposits because of the distribution of the late Proterozoic Wendell temple group and the magmatic rock and favorable structures of different periods , so greater attention should be paid on it. |
