查询词典 Sr

On the basis of the information obtained through field geological survey and indoor integrated petrological and petrochemical studies, it has been found that there is a clear and sharp pulsatory intrusive contact between various rock units of the rock body and a number of dark dioritic microinclusions are present. The rocks are characterized by a relatively low total REE content, relative enrichment in K, Rb, Ba and Th and relative depletion in Cr, Ti, Nb, Sr and P.

根据野外地质调查资料和室内的岩石学、岩石化学等特征的综合研究成果，发现该岩体各单元之间呈脉动式侵入接触，接触界线清晰，且含有较多暗色闪长质微粒包体；稀土总量较低，K、Rb、Ba、Th元素相对富集，Cr、Ti、Nb、 Sr、Zr、P元素相对亏损。
