长白山火山构造与火山喷发研究进展

Research Progress in Tectonic and Eruption of Changbai Mountain Volcano

长白山火山是世界著名的具有潜在灾害性喷发危险的火山之一,对长白山火山的研究是目前地质灾害研究的重要内容。梳理和总结了近期国内有关长白山火山构造、喷发机制、火山喷发物等方面的研究,初步确定长白山天池火山岩浆囊处于火山口下方10~40 km处,天池火山口西南对火山喷发熔岩流向有控制作用,该区地质构造受西太平洋板块俯冲作用的影响,火山区地壳和地幔双层岩浆房具有互动式喷发特点。同时提出火山内部岩浆结构、位置、演化和喷发机制等内容仍是今后深入探究的课题。

Changbai Mountain volcano is famous with potentially catastrophic eruption of the volcano dangerous in world. The study of Changbai Mountain volcano is an important part of the research on geological disaster. It summarized and carded recent research what is relevant domestic Changbai Mountain Volcanic structure, eruption mechanisms, volcanic eruptions and other aspects of the study. Tianchi volcano magma chamber was initially identified in the crater at the bottom of 10~40 km. It eruption crater could control southwest lava flows.The geologic of the region is influenced by the actions of the Western Pacific' pitch down. And volcanic crust and mantle magma chamber has a double eruption interactive feature. It is still a subject what we export deeply that bring up inside the volcano of magma, location,evolution and eruption mechanism in the future.
