山东省地质矿产勘查开发局60年重要找矿成果和深部隐伏区找矿技术进展

山东省地质矿产勘查开发局建局60年来,以资源报国为己任,全力为山东省和国家经济建设提供资源保障,取得了巨大找矿成就。该文较全面总结了山东省地质矿产勘查开发局60年取得的重要找矿成果和近年来深部和隐伏区找矿技术进展。20世纪,发现了焦家式新类型金矿,探明全国三分之一的黄金储量;发现了中国第一个金刚石原生矿和最大的蓝宝石矿,找到了一批大煤矿、大铁矿、有色金属矿和非金属矿。新世纪以来,山东省地质矿产勘查开发局省内、省外、境外三线联动全方位开展找矿突破行动,省内深部找矿成果突出,探明了10余个资源量超过100t的大金矿,尤其是在三山岛北部海域探获了470t的全球最大的海底金矿床;省外,在新疆和内蒙分别探明了重要的煤矿床和多金属矿床;国外,在刚果(布)、秘鲁、澳大利亚、津巴布韦、肯尼亚等国家探获了特大型钾盐、铁、金刚石和硅藻土矿床。研发和建立了以深部金矿阶梯式找矿方法为代表的一系列深部和复杂条件找矿技术方法。

Important Prospecting Achievements and the Development of Ore Prospecting in Deep Hidden Area Gained by Shandong Exploration Bureau of Geology and Mineral Resources in 60 Years

In the past 60 years, Shandong Exploration Bureau of Geology and Mineral Resources(SDGM) insists on prospecting to serve the country as own duty, to provide resources guarantee for the economic construction of Shandong province. So they made great achievements in prospecting. This paper comprehensively summarizes the important prospecting achievements and latest technological advances of deep and concealed prospecting by SDGM. In the 20th century, a new type of gold deposit of Jiaojia type was discovered, and onethird of the country''s gold reserves was proven. China''s first primary diamond deposit and the largest sapphire deposit had been discovered, and a batch of largescale coal deposits, iron ore deposits, nonferrous metal deposits and nonmetal deposits had been found. Since the 21th century, SDGM implement National Exploration and Development Planning in the innerprovince, outerprovince and overseas. In the innerprovince, outstanding achievements in deep prospecting has been made, and more than 10 large gold deposits with a reserves of over 100t have been discovered, especially a world''s largest undersea gold deposit with 470t reserves has been detected. In the outerprovince, important coal deposits and polymetallic deposits have been discovered in Xinjiang and Inner Mongolia respectively. In other countries, such as Congobrazzaville, Peru, Australia, Zimbabwe and Kenya, a batch of largescale potash, iron, diamond and diatomite deposits have been detected. A series of deep and complex condition prospecting methods are developed and established, such as stepwise prospecting method for deep gold deposits.
