查询词典 mantle

The geochemical characteristics of basic to intermediate-basic igneous rocks indicate that they belong to a tholeiite suite. Their chondrite-normalized REE patterns are of nearly flat and slightly LREE-enriched type, and their primitive mantle-normalized and MORB-normalized trace element spidergrams are generally similar; the LILEs Cs, Ba, Sr, Th and U are enriched, while Rb and K and the HFSEs Nb, P, Zr, Sm, Ti and Y are depleted. All these show comagmatic evolutionary and genetic characteristics.

基性—中基性岩浆岩的地球化学特征表明其属于拉斑玄武岩系列，稀土元素分布型式呈REE近平坦型—LREE轻微富集型，微量元素原始地幔标准化的蛛网图和MORB标准化蛛网图上的分布型式总体很相似，富集大离子亲石元素Cs，Ba，Sr，Th，U而相对亏损Rb，K和高场强元素Nb，P，Zr， Sm，Ti和Y，显示同源岩浆演化成因特征。

This paper reports the investigation on the petrology of spinel harzburgite and olivine pyroxenite in the Darbut ophiolitic mélange, as well as the worm-like intergrowth texture composed of Cr-spinel and orthopyroxene wide-spreading in harzburgite. Our study shows that the observed intergrowth texture is not a graphic texture or a symplectite as assumed by previous research, instead, it is a product of the evolution of the Cr-rich magma formed after the melting of the primitive mantle.
