远东中俄边界地区的火成活动

THE IGNEOUS ACTIVITIES OF THE FAR EAST SINO RUSSIA BORDER

本文以远东中俄边界地区广泛发育的火成岩的研究为基础，对火成活动在地体构造演化历史中的构造背景、不同阶段的发育特点、形成的岩石组合和动力学机制等作了探讨。得出地体构造从早及晚由挤压向伸展和走滑构造背景演化，相应发育一系列具有成因特征的火成岩。为古亚洲洋东段的构造演化提供了佐证。

On the basis of researching widely developed igneous rocks,the tectonic setting in theterrain structure evolutionary history for the igneous activities ,the developed characteristicsin different stages and the formed rock association and dynamic mechanism are discussed.The development of terrain structure is under the evolutional background from compressionto extension and to strike slip structure from early to late,associated with a series of the ig-neous rock with genetic characteristics,providing an evidence for the structure evolution inthe east part of Paleoasiatic ocean.
