摘要
纳米级微粒测量是寻找隐伏矿的新方法,选取实地模拟实验和在已知隐伏矿区,利用液态捕集剂和等离子体质谱分析测试样品,进行重复测量试验,研究结果表明,不同成矿元素,在地表形成异常的运移富集速率不同,其运移速率主要取决于纳米级微粒本身的地球化学性质,地下上升气流、断裂等裂隙有利于微粒的上升运移富集;纳米级微粒地球化学重复测量时,异常可具有良好的重现性,但异常重现较常规气体缓慢,通常需要2~3个月。
Nanometer particle survey is a new geochemical method for prospecting for hidden ore deposits. An in-situ experiment and a test survey in a known hidden deposit, as to examine the reproducibility of anomalies, have been carried out by using liquid collector for sampling and ICP-MS for analyzing samples. The results show that migration-enrichment rates of ore-forming elements upward to the surface are different from each other, depending on geochemical properties of the elements, ascending gas flow and fract...
