火山岩

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。

And it reflects that the magmatism time of Ailaoshan-Jinshajiang potassic alkalic rock zone from east is younger than west magmatism time. The time is from the middle of Eocene to Miocene. The durative time of magmatism is 40Ma.

这种因果关系，反映了青藏高原在两个大陆碰撞之后继续向北偏东(21°)推移，受到了塔里木、柴达木和康滇古陆古老基底的阻挡，导致了长达数千公里的金沙江-红河走滑拉分带的形成，同时伴随着钾质碱性深成岩和火山岩产出。

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.

Kamafugite is an ultra potassic volcanic rock occurred in oceanic and/or continental settings, especially in continental rift. Kamafugite is also an igneous rock outcropped very rarely in the world.

钾霞橄黄长岩是一种产于大洋和/或大陆环境，尤以大陆裂谷最为多见的超钾质火山岩，也是世界上出露最少的火成岩之一，目前世界只有少数几个国家和地区有这类岩石的报道。

Ore deposit, have been studied detailly; the orebody pattern (sedimental bedded ores combined with stringer ores of hydrothermal origin) is also outlined; four metallogenic epoches are devided; the zoning of mineralization (including zones of ores, elements, mineral assemblages and temperature of mineralization) have been depicted; the main types of wall-rock alteration are characterized as propylitization of basic rocks and pyritization-sericitization-silicification of acidic pyroclastic rocks; the origin of ores and seven kinds of main minerals have been studied; and the metamorphism and deformation of orebodies is thought mainly due to the shearing and the intrusion of subvolcanic rocks

研究了七个矿化带特别是I号矿床的矿床地质特征，描绘了矿体的双层结构(沉积矿石与热液充填交代的细网脉状矿石)，划分了四个成矿期次，区分了矿化分带(包括矿石组构的成因分带、元素分带、矿物组合分带、温度分带)，指出了围岩蚀变的主要特征是细碧岩青盘岩化而石英角斑质凝灰岩黄铁绢英岩化；对矿石及七种主要矿石矿物的成因作了研究；探讨了矿体的变质、变形，指出韧性剪切及次火山岩侵入的热力作用和应力作用是导致矿体变质变形的主要原因

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。

On the basis of an integrated analysis of the geochemical features of these volcanic rock associations,this paper concludes that thebasalts originated mainly from interaction between mantle-derived magma and low-crustal materials, and rhyolitic volcanic rocks resulted from thermal and chemical interaction between basaltic magma and the upper part of crustal materials.Basalts and rhyolites in different cycles have different source regions,and they are products of multiperiodic pulsive layer partial melting.

根据对火山岩地球化学特征的综合分析表明，玄武岩主要为幔源岩浆与下部地壳岩石相互作用的产物，而流纹岩则为玄武岩浆与上部地壳物质进行热及成分交换的结果，不同旋回的玄武岩和流纹岩有不同的源区，为多次脉动分层部分熔融的产物。

Under the action of which pyrogenic rocks, volcanic complex

在这些作用下，形成了火成岩，火山岩的复合物，水成岩，沉积岩，以及他们的共生物

Under the action of which pyrogenic rocks, volcanic complex, aqueous rocks, sedimentary rocks etc.

在这些作用下，形成了火山岩，火山复合岩，水成岩及沉积岩

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
