从美国内华达州卡漠矿区的金含Au、Ag石英脉及其有关火山岩中采集了92个样品,对Au,Ag,T1,Rb,K,Ba和S_1进行了分析,并计算了K/T1、K/Rb、Ba/T1、T1/Sr的比值。 从未蚀变安山岩到蚀变安山岩和含Au,Ag石英脉,AuAg含量以及T1/Sr、Rb/Sr比值依次升高,而K/T1、K/Rb、Ba/T1比值降低,T1与Rb和K的这种关系显示出在矿化岩石中的T1比Rb更富集,而Rb则比K更富集。根据研究所获得的资料表明,在圈定 与火山岩伴生的Au,Ag含量变化颇大(因其在自然界分布极不均匀)的贵金属脉状矿床中,T1的含量及Ba/T1、K/T1比值可作为有效的勘探手段。
A total of 92 samples were collected from the gold-bearing Au and Ag quartz veins and their related volcanic rocks in the Nami area in Nevada, Nevada. Au, Ag, T1, Rb, K, Ba and S_1 were analyzed and K / T1 , K / Rb, Ba / T1, T1 / Sr ratio. The ratio of K / T1, K / Rb and Ba / T1 decreased gradually from unchanged andesite to alteration andesite and quartz containing Au and Ag, and the ratio of T1 / Sr and Rb / Sr increased gradually. This relationship with K shows that T1 in mineralized rocks is richer than Rb, whereas Rb is richer than K. According to the data obtained from the research, it is shown that the content of T1 and the ratio of Ba / T1 and K / T1 in the delineation of precious metal vein-like deposits that vary greatly with Au and Ag associated with volcanic rocks (due to their extremely uneven distribution in nature) Can be used as an effective exploration tool.
