tholeiitic magma

The basic volcanic rocks of the first cycle belong to the alkali basalt magma series and those of the second and the third cycles the tholeiitic magma series.

第一旋回基性火山岩属碱性系列，第二、三旋回基性火山岩属拉斑玄武岩系列。

They were derived from different magma series: the gabbro was derived from tholeiitic magma series with higher TiO_2, REE abundance and Fe~ ( 3+)/ Fe ( 2+) ratio;

它们分属两个不同的岩浆系列：辉长岩属拉斑系列，TiO2，Fe~（3+）/Fe~（2+）和REE丰度较高；

The magma originated from the upper mantle and belongs to the tholeiitic series which has undergone immiscible separation of metal sulfide.

岩浆起源于上地幔，属于拉斑玄武岩系列，发生过金属硫化物的熔离作用。

浙江沿海晚中生代拉斑玄武岩浆侵位深度的讨论

There was a syn-orogenic uplift-extensional tectonic setting in the terminal Late Triassic-Early Jurassic(ⅱ 3), when the NNE-directed rift coal-bearing basins formed and high-Na and low-K tholeiitic magma was erupted.

晚三叠世末&早侏罗世（Ⅱ3）为同造山上隆伸展环境，形成NNE向裂陷含煤盆地，高Na低K的拉斑玄武岩喷发。

The basic rocks, which belong to alkali and tholeiitic magma series, enriched in LREE and LIL. The magmatic source of basic volcanic rocks was enrichment mantle being analogous to oceanic island basalts sources.

基性火山岩有磁性玄武岩与拉斑玄武岩两个岩浆系列，且富集LREE与LIL，其岩浆源区为与洋岛玄武岩源相似的富集地幔柱源。
