摘　　要：通过研究发现,世界上产出的金刚石原生矿在大地构造环境、岩石特征、特征矿物等方面虽有所差异,但在控矿地质条件、地球物理化学特征、金刚石特征和找矿方法等方面具有较强的共性特征。金刚石原生矿找矿具有投入大、工作周期长、风险高的特点,其勘查技术方法有其特殊之处。该文在前人研究成果的基础上,总结大地构造环境、控矿地质特征、金刚石及其指示矿物特征、物化探异常特征,结合金刚石原生矿找矿方法,建立了金刚石原生矿综合找矿模型,对于金刚石原生矿的找矿工作具有一定的指导意义。Through study,it is found that although geotectonic environment,rock characteristics and characteristic minerals of the primary diamond deposits in the world are different,there is a strong common characteristics in ore-controlling geological conditions,geophysical and chemical characteristics,diamond characteristics and prospecting methods.The primary diamond ore prospecting has the characteristics of large investment,long working period and high risk.Its prospecting technology and methods have their own particularities.On the basis of previous research results,geotectonic environment,ore-controlling geological characteristics,diamond and its indicative mineral characteristics,geophysical and geochemical anomaly characteristics have been summarized,a comprehensive prospecting model for primary diamond deposits combining with the exploration method of prospecting primary diamond deposits has been established.It has a certain guiding significance for the exploration of primary diamond deposits.
