摘要
1∶20万水系沉积物测量结果表明,粤北大东山地区富集Sn、W、B i、Pb、Ag、F、B,且分布不均匀,叠加富集程度高,圈出的综合异常规模巨大,出现多个浓集中心。选择分析了潭岭、称架浓集中心的异常特征和所处的地质背景,认为成矿条件好,具较好的找矿潜力,以寻找云英岩型、蚀变构造带型、蚀变岩体型、石英脉型锡钨矿为主。
1： 200000 stream sediment survey shows that Dadongshan area of Guangdong Province is enriched in Sn, W, Bi, Pb, Ag, F and B, which are characterized by uneven distribution and high degree of superimposed enrichment. The delineated composite anomalies are large in size and show quite a few concentration centers. In this paper, Tanling and Chengjia concentration centers were chosen to analyze the anomaly characteristics and geological settings. It is held that these centers have favorable ore-forming conditions and ore-prospecting potential, and hence are suitable places in search for greisen type, altered tectonic belt type, altered rock body type and quartz vein type Sn and W deposits.
