| 摘 要： | 扬子克拉通金刚石原生矿找矿问题一直是极具争议和挑战性的课题,而贵州镇远作为扬子克拉通最丰富的含金刚石母岩出露区,对该区岩体侵位模式及找矿前景的研究,可为扬子克拉通金刚石成矿与找矿研究、地球深部重大科学问题探讨等提供新的思路和方法。通过梳理分析以往该区形成的勘查、研究资料,认为贵州东部所出露的一系列钾镁煌斑岩体受控于北东向的玉屏-施洞-三都断裂,就镇远马坪而言,至少出露2期钾镁煌斑岩侵入活动,在其深冲断层东侧可能存在未被剥蚀的岩体,仍具有一定的找矿前景。

| Abstract: | The Maping area of Zhenyuan County in Guizhou Province is the first primary diamond deposit discovered in China and is also the only outcrop of diamond-bearing parent rock area in Guizhou Province. The study of rock type, mineral composition and geochemical characteristics of lamproites and emplacement time of plutons in this area has been carried out for a long time, and most researchers hold that the plutons in the area have been denuded to the root facies, the quality of the selected diamond is poor and the prospects for prospecting are not good. The exploration of the primary diamond deposits beneath the Yangtze Craton has long been a controversial question. Zhenyuan area of Guizhou Province is the most abundant outcropping area of diamond-bearing rocks in the Yangtze Craton, and hence the study of emplacement model and ore-search prospect of lamproite in this area will be helpful to providing new ideas and methods for the research on Yangtze craton diamond prospecting and exploration so as to investigate major deep earth science problems. Through the analysis of regional information available, it is considered that a series of porphyritic lamproites exposed in the eastern part of Guizhou are controlled by the Yuping-Shidong-Sandu faults in the northeast, that at least two phases of intrusive activity of lamproite occurred in Maping area, and that, on the eastern side of the Shenchong fault, plutons might have not been denuded, and hence this area still has some ore-search prospects. |
