岩石圈

Not only is the present Yangtze craton constrained by regional compressional stress field but also its cold and dense lithospheric root is descended into the deep mantle by negative buoyancy, Which further strengthens inward obduction of orogenic belts surrounding it. For examples, Longmen shan mountain, Huaying shan and Bamian shan mountains override onto western margin and eastern part of Sichuan basin, respectively.

现今的扬子克拉通不仅受大区域挤压应力场背景制约，同时其冷而致密的巨厚岩石圈根正在向深部地幔下拽，从而进一步加剧了四周造山带向盆地的逆冲作用，龙门山、华蓥山和八面山分别向川西盆地和川东逆冲就是例证。

The mafic dikes also formed by the partial melting of enriched mantle, include gabbro, diabase and lamprophyres (camptovogesite, odinite and hornblende lamprophyres).

基性脉岩主要包括辉长岩、辉绿岩和煌斑岩(以斜闪煌斑岩为主，同时含部分拉辉煌斑岩和角闪煌斑岩)，都为富集岩石圈地幔部分熔融的产物。

This orogenetic process is a series of completed tectonic evolution, reflecting the initial orogenic magma underplating and magma mixing, the peak orogenic strong interaction between the crust and mantle, the late orogenic lithosphere started to delaminate and the post—orogenic extensional tectonic setting.

该造山过程为一套完整的演化序列，反映了初始造山的岩浆底侵作用，峰期造山强烈的壳幔相互作用，后期造山岩石圈开始拆沉作用及后造山的伸展构造背景。

A reasonable mechanism is delamination that had happened at ~11Ma in Pamir syntax.

比较合理的解释是该区在～11Ma时发生了大规模的岩石圈拆沉作用。

On the basis of P-T estimated results and geophysical data, the petrological zoning model of Mesozoic lithospheric mantle in eastern North China block is set up in the thesis.

依据深源岩石包体的P-T条件估算结果，结合地球物理测深资料，本文建立了华北地块东部中生代岩石圈地幔的岩石学分带模型。

Cenozoic potassic and ultrapotassic lavas in the north Tibet are the direct result of northward subducting of ILM.

因此，青藏高原北部新生代火山岩可能是印度岩石圈地幔持续北向俯冲的结果。

During these events, the potassic volcanic rocks of Oulituozi were produced during extension stage of the rift with subsequent fractional crystallization and derived from basaltic magma.

欧利坨子富钾质火山岩的形成是裂谷期岩石圈伸展作用的产物，是玄武质岩浆经过大比例分离结晶作用的产物，可能与晚中生代太平洋板块俯冲残片的部分熔融有密切关系。

During these events, the potassic volcanic rocks of Oulituozi were produced during extension stage of the rift with subsequent fractional crystallization and derived from basaltic magma. The genesis of the volcanic rocks possibly had a close relation with partial melting of the subducted slab of Pacific Plate oceanic crust.

欧利坨子富钾质火山岩的形成是裂谷期岩石圈伸展作用的产物，是玄武质岩浆经过大比例分离结晶作用的产物，可能与晚中生代太平洋板块俯冲残片的部分熔融有密切关系。

These evidences lead to the conclusion that the Late Mesozoic volcanic activities in the study area are related to pulsative up-welling diapirs of asthenosphere, for which a natural passage is provided by the specific tectonic background confined by large-scale lithospheric faults in the study area.

根据上述特点，提出辽西晚中生代的火山岩活动可能与软流圈底辟体脉动式上涌有关，研究区被岩石圈断裂围限的特定构造背景为软流圈底辟体的上涌提供了天然通道。

The close time_space relationship between shoshonite in the northern part of Siziwang Banner and fluorite mineralization implies that the fluorite deposit might have resulted from the lithospheric thinning of eastern China and the replacement of the lower crust.

萤石成矿作用与钾玄岩的时空关系暗示了萤石的成矿过程可能是中国东部岩石圈减薄和下地壳的置换地质事件的结果。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
