玄武岩

Geochemical analysis results of the basalts indicate that they were formed within oceanic plate.

玄武岩样品的地球化学分析结果表明，它们形成大洋板内构造背景，这证实了对古特提斯东延的设想，并有必要重新认识广西晚古生代地质演化的历史

In contrast, the less abundant HT and LT2 basalts may imply a weakening of the influence of the mantle plume activity.

相反，厚度较小的HT和LT2玄武岩则可能是意味着地幔柱活动影响的减弱。

Answering these problems will play an important role not only in the study of the Emeishan basalts and the mantle_plume interaction, but also in the investigation of their relation to mineralization.

这些问题的解决，对研究娥眉山玄武岩本身以及地幔柱－岩石圈的相互作用及其成矿效应均具有重要意义。

PGE parameters of the Dashibao Formation basalts are identical to the general trend of the Zhengziyanwo intrusion, and this might infer that there is a genetic link between them.

大石包组玄武岩的PGE参数与正子岩窝岩体的总体趋势具有很好的吻合性，暗示着两者之间具有一定的成生联系。

It may indicate that the Martian mantle is wetter than Earth's or that younger lavas melted at different temperatures or pressures than the older basalts.

或许代表火星的地函比地球的更潮湿，或是较年轻的熔岩与较古老的玄武岩是各在不同的温度或压力下熔化。

We examined the origin and source of both high-Ti and low-Ti basalts of most large igneous provinces on Earth and found that they are generated from distinct mantle sources, rather than time-dependent.

根据对地球上两类玄武岩的源区和成因研究，发现它们应该是来自不同的地幔源区，而与其形成的时间没有关系。

REE abundances and Sr and Nd isotopic composition in mantle xenoliths from basalts in Hannuoba are reported in this paper.

One component is thought to have been derived from the lithospheric mantle, and the other was derived from an asthenospheric source similar to that of Hawaii, Iceland and Reunion basalts.

一种组分来源于岩石圈地幔，另一种组分来源于与夏威夷、冰岛和留尼汪岛等洋岛玄武岩源区相似的软流圈。

The geochemical characteristics and behavior of rare earth elements in soils developed on the basalts in the northern part of Hainan Island erupted in different time were studied as well as the REE partition in the soil formation process and its implication on soil development degree.

研究了海南岛北部不同时期喷发的玄武岩上发育土壤中稀土元素的地球化学特征和行为，探讨成土过程中稀土元素的分异及其对土壤发育程度的指示作用。
