为了搞清独联体国家(不包括中亚)现代冲积层的总体砂矿地球化学本底,对36条河的沉积物重粒级做了125个半定量光谱分析。分析工作是在三个实验室进行的;乌拉尔中心实验空、自俄罗斯科学院地球化学和地球物理研究所、彼尔姆地质队。每一个宏观砂矿地球化学省都具有一定的微量元素共生组合。例如,波罗的地球化学省含Ni、Co、W、Li;乌拉尔地球化学省富cr、V、Sc、Sr、Be、Yb;乌克兰地球化学省富Ti、Nb、Ga、Ag等。变化最大的是那些受工艺活动影响元素:Zn、Pb、Cu、Sn。后者在个别样品中可差几个数量
In order to understand the overall placer geochemical background of modern alluvial deposits in the Commonwealth of Independent States (excluding Central Asia), 125 semi-quantitative spectroscopic analyzes of the sediment heavy grain size of 36 rivers were performed. The analysis was carried out in three laboratories; the Ural Center for Experimental Spaces, from the Perm Geological Team at the Institute of Geochemistry and Geophysics of the Russian Academy of Sciences. Each macro-placer geochemical province has some symbiotic combinations of trace elements. For example, the Baltic geochemical province contains Ni, Co, W and Li; the Ural geochemical province is rich in Cr, V, Sc, Sr, Be and Yb; and the Ukrainian geochemical province is rich in Ti, Nb, Ga and Ag. Those most affected are those affected by process activity: Zn, Pb, Cu, Sn. The latter in a few samples can be a few numbers
