中文摘要:

      上世纪80年代以后进行的1:20万水系沉积物扫面, 个别元素分析质量不稳定, 达不到设计要求, 如镉、钴、铜、镧. 利用大型分析仪器为手段, 建立了稀有、稀散、稀土和铂族元素的测试方法, 分析数据符合地球化学填图的要求, 为地质找矿工作新的突破做出贡献.

英文摘要:

      In the general survey of the 1:200 thousand water system sediment csrried out after the 1980's, the quality of elemental analysis of some elements, such as cadmium, cobalt, copper, and lanthanum, was not stable and could not meet the designed requirement. Using the large-scale analytical instruments as a means, test methods for the rare, spares and scattered rare-earth and platinum group elements have been established. The analytical data were in accord with the geochemical mapping requirements. These methods are contributory to the geological prospecting work.
