华北地台金刚石找矿前景及成矿预测

华北地台是我国最重要的金刚石成矿区,已在山东、辽宁找到具经济价值的金伯利岩型金刚石原生矿床,并且在江苏、安徽、河南、河北、山西、吉林等地发现金刚石矿点和重要的找矿信息.依据华北地台金刚石原生矿的成矿规律及物化探、重砂综合信息研究成果,将郯庐断裂带、太行山断裂带及华北地台北缘金刚石原生矿成矿区带,大致划分为4个成矿远景区.

EXPLORATION PROSPECTS AND METALLOGENIC PREDICTION OF DIAMOND IN NORTH CHINA PLATFORM

The North China platform is the most important metallogenic province for diamond in China. Primary diamond deposits of kimberlite type with economic value were discovered in Shandong and Liaoning, and diamond ore occurrences and significant prospecting information were also found in Jiangsu, Anhui, Henan, Hebei, Shanxi and Jilin. Based on the metallogenic regularity, as well as the comprehensive information results of geophysical, geochemical and heavy mineral prospecting research for the primary diamond deposit in North China platform, four metallogenic prospective areas are identified in the metallogenic province of primary diamond deposit in Tanlu fault zone, Taihang Mountains fault zone and the northern margin of North China platform.
