玄武岩

The gold content of mantle-derived xenoliths are usually higher than that of their host rocks.

1金在地幔岩包体中的含量通常高于寄主玄武岩中的含量。

Unlike gold, molybdenum content of host rocks is remarkably higher than that of mantle-derived xenoliths.

(1)与金不同，钼在寄主玄武岩中的含量显著高于在地幔岩包体中的含量。

Mantle xenoliths from 12 localities in Eastern China are studied in this paper to investigate the composition, thermal structure, and Redox states of Continental Lithosphere beneath Eastern China.

本文以中国东部新生代碱性玄武岩中12个代表性产地的深源包体为研究对象，对中国东部大陆岩石圈的成分、热结构与氧化状态进行了较系统的研究。

Gold, molybdenum and tungsten contents in the samples of deep-seated Xenoliths and their host rocks from Anfeng peak were analyzed.

本文对中国东部江苏东海县安峰山一带的深源包体及其寄主玄武岩中Au、Mo、W含量进行了较系统的分析，得到较系统的基础数据。

The helium isotope results of nodules in C-CZone, eclogite in Dabie-Sulu region and mantle xenoliths and xenocrysts in Cenozoic basalt ineastern China were reported in this thesis.

本文重点介绍了C-C区海底多金属结核、大别山榴辉岩和中国东部新生代玄武岩中幔源包体的氦同位素研究成果。

The variations of helium isotopic ratios can be observed in these xenoliths andxenocrysts from different area, or even from same area, indicating that the xenocrysts didntdirectly crystallize from basaltic magma, and basaltic magma is not directly related to thesemantle lherzolites xenoliths.

提出幔源包体和高压巨晶的氦同位素组成均反映了其地幔源区的特征，与寄主玄武岩无必然成因联系。

Thee seismic area is covered with the Basalt at Post-Tertiary Period.

震区被晚第三纪玄武岩覆盖，地面未发现第四纪活动断裂。

The central peaks of several craters on the flanks of Syrtis Major are made up of an even more silica-rich rock, granite, that may have formed by extreme crystal separation or by large-scale remelting of earlier basalts.

在大三角侧面，几个火山口的中间尖点是由一种矽含量更高的岩石──花岗岩所构成，可能是经极度晶体分化，或早期玄武岩大范围重新熔融而形成。

The activities of soil urease, acid phosphatase, sucrase and catalase were higher than those from alluvial soil by 20.3%, 121.0%, 122.2% and 11.9%.

玄武岩发育形成的土壤脲酶、酸性磷酸酶、蔗糖酶和过氧化氢酶活性比冲积土的分别高20.3%、121.0%、122.2%和11.9%。

The results show that the main gold ore bodies were produced near the interruption of sedimentation between Maokou Formation and Emeishan Basalt, which is a characteristic ore-forming combination composed of ore source bed, fluid passageway and ore-hosting space.

研究结果表明，泥堡矿床最主要的金矿体产于茅口组与峨眉山玄武岩组之间的沉积间断面附近，是一个集矿源层、流体通道和容矿部位于一体的极具特色的成矿组合。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
