球粒陨石标准化的稀土元素分布型式表明二辉橄榄岩和方辉橄榄岩具有平坦的分布型式,二辉橄榄岩分布在世界二辉橄榄分布区域内,方辉橄榄岩HREE含量较低;辉石岩的分布型式与印度洋中脊玄武岩公布型式相近,玄武岩的分布型式明显亏损重稀土元素,它与夏威夷碱性橄榄玄武岩分布型式相近以.稀土元素分配系数的计算表明,二辉椰榄岩和玄武岩岩浆之间、方辉橄榄岩阳辉石岩岩浆之间处于平衡.辉石岩岩浆和玄武岩岩浆是起源于上地慢的原始岩浆.这与辉石岩和玄武岩主要元素的化学成分一致.稀土元素的研究暗示了该区土地馒曾发生过稀土元素的分异.在辉石岩浆形成之前,在上地幔的较高部位即玄武岩岩浆的源区轻稀土元素微具富集,而在上地幔的梢下部位即辉石岩岩浆形成的源区轻度亏损了轻稀土元素
The normalized REE distribution patterns of chondrite indicate that the lherzolites and harzburgites have a flat distribution pattern, and the lherzolites are distributed in the distribution area of the bifold olive in the world, and the HREE content of the karst rock is relatively low. The pyroxene The distribution pattern of rock is similar to that of Indian mid-ocean basalts, and the distribution pattern of basalt obviously depletes heavy rare earth elements, which is similar to that of Hawaiian basal olivine basalts. Calculations of REE distribution coefficients show that the two types of coconut and basalts The magma is in equilibrium with the harzburgite-pegmatite magma.The pyroxenite and basaltic magma are the primitive magmas that originated from the upper to the slow, consistent with the chemical composition of the major elements of pyroxene and basalts.Rare earth The study of element implies that the rare earth elements have been differentiated in this area before the formation of pyroxene magma.The LREEs are enriched in the upper part of the upper mantle, The lower part of the shoot, pyroxene magma, forms a light source of light rare earth elements
