摘要
铬是中国最紧缺的矿种之一,长期以来依靠进口,资源安全难以保障,但国家对于铬铁矿的找矿工作一直是很重视的。2006年以来全国开展的25个重要矿种潜力评价工作中就包括铬,本文通过对全国铬铁矿成矿规律的研究,划分出13个矿集区,认为西藏罗布莎、新疆达拉布特和内蒙古贺根山3个矿集区成矿条件最好,找矿潜力最大,目前宜深入研究其深部找矿的技术方法,加强对深部控矿条件的分析,总结深部探测的经验,力争通过攻深找盲来取得找矿突破。
Chromium is one of the most scarce mineral resources in China.For a long time,its need has been mainly met by imports,and it is very difficult to guarantee the security of resources.China has hence attached great importance to the chromite ore prospecting.Since 2006,China Geological Survey has implemented the plan of potential evaluation for 25 kinds of important mineral resources,including Cr.Based on the research on the metallogenic regularity of chromium,this paper preliminarily assigned chromium deposits in China to 12 large ore concentration areas.Meanwhile,based on the most recent progress and data obtained in recent years,the authors hold that Lhobasar,Dalabute and Hegenshan areas are the most important concentration areas in China.This paper describes the three most important ore concentration areas in detail,and discusses their resource potentials separately.
