Abstract

In terms of petrochemical and trace-element data, basalts from the axial rift valley are suggested to originate from sources of the sub-continental lithospheric mantle, inhomogeneity of which was due to extracting upper and lower crustal components. Trace-element modeling indicated 3-8 %partial melting of apatite-bearing sources with varying garnet and clinopyroxene proportions.

来自次大陆岩石圈地幔的Bystraya带玄武岩:贝加尔湖裂谷系的Tunka山谷

根据石油化学和微量元素资料，认为轴向裂谷的玄武岩来源于次大陆岩石圈地幔，其不均匀性是由于提取了上下地壳成分所致。微量元素模拟表明，含磷灰石的矿源部分熔融3- 8%，石榴石和斜辉石的比例不同。
