THE GEOCHEMICAL CHARACTERISTICS OF RARE EARTH ELEMENTS OF THE SHALE ROCK IN THE GEOLOGIC SIGNIFICATION OF THE ANALYSIS OF THE SEDIMENTARY PROVENANCE: AN EXAMPLE IN THE UPPER PALAEOZOIC IN THE ORDOS BASIN
泥质岩稀土元素地球化学特征在物源分析中的意义――以鄂尔多斯盆地上古生界为例

Based on the analysis of rare earth elements of the shale rock of the upper Palaeozonic in the Ordos basin, the rare earth elements are enrichment in variegated mudstone and are deficit in melanoeratie mud rock. Miner-grain sediment had a high pink and micro-grain one had a very weak. According to the regional distribution of rare earth elements, the source of the northern Ordos basin come form the Yinshan ancient land, and the source had zonation in east and west area. The sediment differentiation affections control the enrichment of rare earth element. With mudstone particle size become fine form north to south Ordos basin, rare earth elements had a very pink.
