摘　　要：研究了深穿透地球化学样品中铂、钯、金的水提取态、黏土吸附与可交换态、有机络合物态以及铁锰氧化物结合态等不同相态的测定方法。方法检出限Pt0．03ng／g，Pd和Au0．01ng／g。通过在隐伏铂钯矿或矿化区的试验，结果表明所圈定的异常与实际矿（化）体相符，为寻找与识别隐伏贵金属铂钯金矿床提供了有效信息，对寻找隐伏矿床具有一定的指导意义。Platinum-palladium-gold determined by ICP-MS from the deep penetrating geochemical samples is studied in the paper, as well as the testing methods of different phase states of them. Pt 0.03ng/g, Pd and Au 0.01ng/g are determined by the method. The results of the experiments in the blind Platinum-palladium deposit and the mineralization zone are conforming to the actual deposit. It supplies effective information for searching and distinguishing the Mind noble platinum and palladium deposit, it also has some instructive significance for searching blind deposit.
