This implies a major stage of crustal growth in Proterozoic time and remelting of the crustal material in Early Jurassic time;(5) The Oligocene-Miocene adakites contain magmatic zircons that show similar Hf isotope compositions to the Cretaceous-Paleogene Gangdese batholiths, providing a key constraint that allows evaluation of the nature and timing of crustal thickening in southern Tibet owing to the India-Asia collision; and (6) As a whole, the Hf isotope information observed in zircons from the above Transhimalayan rocks demonstrates a temporal variation in εHf values, and thus TDMC ages, that suggests multiple stages of orogenic or crustal formation events.

五、渐新世、中新世的埃达克岩，其岩浆锆石的铪同位素特徵与白垩纪、古第三纪冈底斯岩浆相似，因而为藏南在印亚碰撞以后，地壳增厚的时间与机制提供了关键性的制约；六、综观上述藏南火成岩中的锆石，它们与时变化的铪同位素初始值及其对应的模式年龄记录了拉萨地块多阶段的造山与地壳形成历史。

The authors think that the magmas of the intermediate-acid volcanic rocks were derived from basaltic magmas of the lower crust and are mixed magmas produced by the increase of geothermal gradients due to diapiric injection of basaltic magmas and partial melting of intermediate-basic metamorphic igneous rocks in the lower crust,and that they resulted from a series of tectonomagmatic activities that took place when the closing of the Mongolian-Okhotsk sea trough and continent-continent collision caused crustal thickening and brought about the formation of the Hinggan-Mongolian orogenic belt in the process of oblique subduction of the Paleo-Pacific plate beneath the Siberian plate.

中文摘要：通过对大兴安岭北段晚侏罗世吉祥峰组中酸性火山岩的岩石地球化学研究，发现其中存在高Sr低Y型火山岩，即文献上所称的埃达克质岩，笔者认为中酸性火山岩的岩浆起源于下地壳玄武质岩浆，为玄武质岩浆底辟上侵引起地热梯度增加、下地壳中基性变质火成岩石部分熔融的之混合岩浆，是古太平洋板块向西伯利亚板块斜向俯冲过程中，蒙古鄂霍次克海槽封闭，陆壳碰撞使地壳加厚，形成兴蒙造山带时所引起的一系列构造岩浆活动。

Study suggests the strata of this block are of the following feature: various sequence interface types, first-class fault and tectonic movement control strata framework styles; formation and evolution of Maodun sub-high makes single-lined fault dustpan-type depression complicated to produce unsymmetrical grabens and igneous rock, which influences detrital rock infilling pattern in the depression.

研究认为，本区地层格架有以下特点：多种层序界面类型、地层格架的样式受凹陷内一级断层和构造运动的控制、毛敦次凸的形成及演化将单断箕状凹陷复杂化，形成不对称地堑、火成岩的发育影响了箕状凹陷的碎屑岩充填模式。

The igneous diversity is not only induced by the magmatic processes but also by the processes caused production of magmas.

火成岩的多样性不仅仅取决于岩浆作用过程，而且也取决于岩浆形成过程。
