文献资料研究表明,对铂族元素特别是在表生环境中的地球化学习性知道很少。本文关于铂、钯在风化旋回中的性状的资料及其解释主要根据蒙大拿州南部斯梯耳沃特杂岩土壤的研究结果,它表明铂族金属对化学风化并非具同样的惰性。本研究集中在两个地区:(1)含有异常铂、钯、铜、镍、铬的铬铁岩层的滑 Documentation studies show little is known about the geochemical behavior of platinum group elements, especially in epiphytic environments. In this paper, the data and interpretation of the trappings of platinum and palladium in weathered cycles are mainly based on the study of Stirlitwater complex in the south of Montana. It shows that the platinum group metals are not equally inert to chemical weathering. This study focuses on two areas: (1) slip of chromitites containing abnormal platinum, palladium, copper, nickel and chromium
