山东省费县朱田地区金刚石原生矿找矿方向探讨

Study on Prospecting Direction of Primary Diamond Deposits in Zhutian Area in Feixian County of Shandong Province

在分析费县朱田地区金刚石原生矿成矿地质条件的基础上,结合最新勘查进展,提出超基性岩体深部、NNE向断裂旁侧及重砂矿物异常点周边可作为今后重点找矿方向,并就该地区金刚石原生矿勘查方法进行了探讨,认为重砂测量法依然是金刚石原生矿勘查行之有效的手段,同时应重视高新技术的应用和找矿新理论的探究,期待形成以大井头岩管为代表的鲁西地区第四金刚石原生矿带,实现鲁西地区金刚石原生矿找矿新突破。

On the basis of analyzing metallogenic geology conditions of primary diamond deposits in Zhutian area of Feixian county, combining with latest exploration achievements, it is pointed out that the deep of ultrabasic rocks, the side of NE trending fault and the periphery of heavy placer mineral anomaly should be the key prospecting directions in the future. Exploration methods have been studied as well in this paper. It is considered that the heavy placer mineral survey is still an effective means of diamond exploration. In addition, more attention should be payed on the application of high technology and study on new exploration theory. It is expected to form the fourth primary diamond ore belt in west Shandong province and achieve a breakthrough in the exploration of primary diamond deposits as soon as possible.
