摘要
在对内蒙古东乌珠穆沁旗区域进行翔实的野外地质调查和针对周围已有勘查矿区、矿床进行类比求异研究的基础上,采用以现有资料综合分析为先导,科学选区到发现弱小异常、成矿信息、野外踏勘、适时设计验证剖面及工程的找矿勘查思路。笔者利用地质理论思维,采取‘就矿找矿法’把勘查工作区选在已知乌兰陶勒盖铜矿西侧阿吉勒地区开展找矿工作,终于在老矿区外围草原覆盖区取得了找矿的突破,通过2008年一年的勘查实践,在矿权密布的阿吉勒地区终于发现了产于火山碎屑岩中的大型多金属矿带,通过后续勘查工作,在该带东段初步提交资源量(334)近11万吨,银资源量(334)近83吨。该带有望发展成为大型多金属矿床。勘查实践表明,要实现找矿的重大发现,扎实细致的资料分析和有针对性的找矿勘查思路是成功的关键。
We have conducted detailed field geological investigations in the eastern Wuzhumuxinqi area of Inner Mongolia,and made a comparison of the exploited ore districts and deposits.Firstly,we have analyzed synthetically existing data,selected target areas scientifically,then detected puny anomalies,metallogenic information,and carried out field reconnaissance.Finally we designed validating sections and prospecting and exploration guidelines of the project.We used geological theory mode of thinking and ‘the methods of mining based on mines’.Our exploration zone was selected nearby the west of the WuLanlaolegai copper deposit.We attempted to search for ore in the AJile district,and we finally made breakthrough of finding ore which is covered with grasslands outside the former mine district.Through prospecting for a year in the Ajile area,where mining priorities are highly claimed,finally we found a large-scale polymetallic ore belt produced in pyroclastic rock.After further exploration,we have determined that Pb＋Zn resources quantity （3341） reaches 110 000 ton and Ag resources quantity（3341） reaches 83 ton in the east part of the belt.And these belts have prospect to become a large polymertallic deposit in the future.Exploration practice shows that it is the key for realizing significant discoveries of prospecting to analyze data sturdily and carefully,and to make strenuous efforts in target-focused exploration.
