本文的主要目的旨在考察伴生有金、银、铀和铜-钼矿床的蚀变岩石中铊的行为,并估价利用铊作为矿床潜在指示剂的可能性。 分析方法 取样 本文中所分析的岩石样品均选自1977—1981年间所采集的500多个地表样品和近150个岩心样品。这些样品采自华盛顿州东北部和蒙大拿州中部的六个矿化区和未矿化区(图1)。 将每个样品的1—5千克岩石压碎。在压碎前先去掉所有风化的或生锈的表面。然后分出100—200克研磨到-100目,用作化学分析。
The main purpose of this paper is to investigate the behavior of thallium in altered rocks associated with gold, silver, uranium and copper-molybdenum deposits and to evaluate the possibility of using thallium as a potential indicator of the deposit. Analytical Methods Sampling The rock samples analyzed in this paper were all selected from more than 500 surface samples and nearly 150 core samples collected during 1977-1981. The samples were taken from six mineralized and non-mineralized areas in northeastern Washington and Central Montana (Figure 1). One to five kilos of rock per sample were crushed. Remove all weathered or rusty surfaces before crushing. Then 100-200 g portions were ground to -100 mesh for chemical analysis.
