赣北大湖塘钨多金属矿田就矿找矿实践与认识

Practice and Cognition of Making Ore Search Nearby in Dahutang Tungsten Ore Field,Northern Jiangxi

大湖塘矿田位于江西北部九岭钨多金属成矿带中部,面积200多平方千米。矿田自上世纪50年代勘查至今,就矿找矿的主要方式有就异常找矿、就浅部矿找深部矿、就单一类型矿找多类型复合矿、就钨矿找钼矿及就模型找矿五种。在勘查过程中,运用地球化学异常、成矿系列、成矿分带及综合信息成矿预测等理论,通过就矿找矿方法,面中求点、由点到面、点面结合开展工作,由异常到发现钨多金属矿床(点),由单一的石英大脉型找矿,向以细脉浸染型、蚀变花岗岩型、脉带型、隐爆角砾岩型为主的“多位一体”矿床系列组合找矿,由单钨矿种向钨钼共生矿种找矿,相继发现了石门寺、狮尾洞、大雾塘、昆山等矿区大—超大型钨钼矿床,实现了地质找矿的重大突破。勘查实践证明,就矿找矿是提高找矿效率、增加资源储量的行之有效的方法。

Dahutang ore field is located in the middle of Jiuling tungsten polymetallic metallogenic belt of northern Jiangxi province,more than 200 square kilometers.The ore field has been inspected since the 1950s.There are five ways to making ore search nearby:prospecting based on anomalies,prospecting for deep deposits based on shallow deposits,prospecting for multiple types of composite ore based on single type ore,prospecting for molybdenum ore based on tungsten ore,and model prospecting.In the process of prospecting,geochemical anomalies,metallogenic series,metallogenic zoning and metallogenic prediction with comprehensive information are used to carry out work on ore prospecting methods,point-to-point,point-to-surface,point-to-point combination. Shimensis,Shiweidong,Dawutang and Kunshan mining areas have been discovered successively,Achieved a major breakthrough in geological prospecting.Proof of exploration practice:making ore search nearby is an effective method to improve prospecting efficiency and increase resource reserves.Major breakthroughs in geological prospecting have been achieved.Exploration practice has proved that prospecting for minerals is an effective method to improve prospecting efficiency and increase resource reserves.
