一、前言辽南金刚石原生矿床是我国著名的金刚石矿床之一,对于本区成矿远景的推断,在六十年代初马元韬工程师根据世界上己知金刚石矿床主要产于古老地台内的隆起与拗陷衔接带的这一规律,提出“在辽宁南部开展金刚石普查工作的意见”,这个意见在十年之后被证实是正确的。辽宁最早的金伯利岩体在1971年辽宁区调队进行1:20万地质调查时所发现,其后经我队十余年的普查勘探工作,先后发现了一批具工业价值金伯利岩管和岩脉;并划分出北东东向的三个金刚石原生矿带组成的矿田;提交了矿床勘探报告。为了进一步总结我区金刚石原生矿床的成矿规律,本文根据部、局“局于开展典型 I. Introduction The primary diamond deposit in Liaoning Province is one of the famous diamond deposits in China. For the reasoning of the prospect of metallogenic prospect in this area, Ma Yuantao engineers in the early 1960s, based on the uplift of the previously discovered diamond deposits in the ancient platform, Defective convergence zone of this law, put forward “in south Liaoning to carry out diamond census work opinions”, this opinion was confirmed after ten years is correct. The earliest kimberlite rock mass in Liaoning Province was discovered during the 1: 200,000 geological survey conducted by the Liaoning Province transfer team in 1971. After more than 10 years of census and exploration work by our team, a group of kimberlite pipes and rocks And divide the orefield composed of three primary diamond strata north-east and east-west; submit the deposit exploration report. In order to further summarize the metallogenic regularity of the diamond primary deposits in our district, this article according to the Ministry, Bureau "Bureau to carry out typical
