摘要
对云南省腾冲已知水热活动区及其邻近区域所做地球化学土壤和岩石测量发现痕量元素异常分带模式,范围从25km^2逐渐扩大至60km^2和200km^2。进行相关分析和聚类分析后绘出谱系图。这个分带模式与热液矿床模式酷似,故对其在矿床勘探及贵金属资源方面的潜力给予评价。
Geochemical zoning pattern of trace-element anomalies in 3 different areas gradually extends from 25 km2, 60 km2 to 200 km2, in the known hydrothermically active areas and their vicinities in Tengchong of Yunnan Province, was determined by geochemical surveys on soil and rocks. Correlation and cluster analyses of the data are made, then hierarchical dendrogram is drawn The pattern is rather similar to that of hydrothermal regime and their potentials in both geothermal exploration and precious-metal resources are evaluated.
