长白山火山地质构造的解析
摘要
白山天池火山区位于中国东北大陆东部,与朝鲜北部相邻。该区处于西太平洋板块俯冲带的前缘位置,与板块俯冲所形成的深源地震相距仅120km。做为中国东北大陆的一部分,该区新生代以来有过多次火山活动。
本次论文在充分收集、研究、利用本区地质普查资料的基础上,明确工作重点,有针对性的开展工作。以地质学、岩石学、地球物理学、地球化学等资料为基础,研究长白山火山区域地壳构造、构造、及应力场的特征,区域构造演化过程;火山活动时的构造作用过程以及火山作用过程中的时空演化与构造作用的分布关系。

ABSTRACT
Changbai Mountain Tianchi volcano area is located in the eastern part of Northeast China and North Korea, China, adjacent. The area lies in the west of Pacific plate subduction zone in the front position, and formed by the subduction of deep earthquakes is only 120km. As a part of Chinese Northeast China, the region since Cenozoic era, there have been many volcano activity.
In this paper, in the full collection of research, based on the geological survey data, a clear focus, targeted to carry out the work. In geology, petrology, geophysics, geochemistry and other data as the foundation, the research of Changbai Mountain volcano area crustal structure, tectonic, and the characteristics of the stress field, tectonic evolution process; the distribution relationship between spatial and temporal activities of the volcano volcano tectonic process and mechanism in the process of evolution and tectonic activity.
Key words:☆:The earthquake; The geological structure; The crust; Volcano activity
