摘要
津巴布韦西部DETT地区属于稳定的克拉通和边部活动带(造山带)结合处。通过总结该地区的伟晶岩型稀有金属矿床的地质特征,结合区域成矿背景、典型矿床特征以及含矿岩石特征的研究,对矿床成因进行分析,认为该矿床成因为早期(古元古代时期)形成的伟晶岩型稀有金属矿床,后不同程度遭受新元古代时期的构造热事件的活化,在此基础上还总结了找矿标志,以期今后在该区寻找类似矿床提供参考。
The DETT deposit is located at the junction of a stable craton and lateral active belt(orogenic belt)in the West Zimbabwe.Based on the summary of the geological characteristics of the pegmatite-type rare metal deposits in this area,the regional metallogenic background and the study of the characteristics of typical deposits and ore-bearing rock series,and the mineral exploration work,the deposit origin has been analyzed.Therefore,it is considered that the deposit belongs to rare metal deposit of pegmatite type,and its genesis is affected by the regional dynamic and hydrothermal contact metamorphism.At the same time,the prospecting marks are summarized in order to provide a reference for exploration of similar deposits in the future.
