良源铷铌钽钨多金属矿床是广东始兴地区新近发现的一处具有特大型远景的矿床。本文在良源矿区1∶1万土壤地球化学测量成果的基础上,对该区W、Sn、Nb等14种元素地球化学特征进行了初步总结,结果发现该矿区W、Sn、Bi、Mo、Pb等元素高度富集,相关分析显示矿区Bi、Nb、Mo、W、Sn等元素之间相关性较强,R-型聚类分析显示元素组合主要有W-Bi、SnBe-Nb等。本次工作共圈定了以W-Sn-Nb为主的组合异常8个,在对其中的上营北和上营南异常的工程验证中均找到了规模较大的铷铌钽钨多金属矿体,显示了该区具有优异的铷铌钽钨多金属矿找矿前景,这一成果为该区下一步找矿指明了方向。
The source of Ndobium tantalum tungsten polycrystalline tungsten ore deposits in Shixing area is newly discovered with a very large prospect of the deposit. Based on the results of 1: 10000 soil geochemical measurements in Liangyuan mine, the authors first summarized the geochemical characteristics of 14 elements such as W, Sn and Nb, and found that the contents of W, Sn, Bi, Mo and Pb The correlation analysis shows that there is a strong correlation between Bi, Nb, Mo, W, Sn and other elements in the mining area. The R-type cluster analysis shows that there are mainly W-Bi and SnBe-Nb elements in the elemental assemblage. In this work, a total of 8 W-Sn-Nb-based anomalies were delineated, and large-scale rubidium-niobium tantalum tungsten polymetallic mines were found in the engineering verification of the Shangying Bei and Shangying South anomalies The result shows that this area has the prospect of prospecting for rubidium, niobium, tantalum and tungsten polymetallic deposits. This result indicates the direction for prospecting in the next step in this area.
