新疆阿什库勒火山群野外地质科学考察

FIELD GEOLOGICAL EXPLORATION OF ASHIKULE VOLCANO GROUP IN WESTERN KUNLUN MOUNTAINS

2011年5月4日至5月30日,由中国地震局地质研究所和新疆维吾尔自治区地震局组成的科考队,完成了2010年度地震行业专项"新疆于田7.3级地震与阿什库勒火山综合科学考察"的野外综合科学考察。火山地质组通过对阿什库勒火山群的野外地质、地貌实地考察,初步查明了阿什库勒盆地新生代火山类型、数量、结构参数和火山活动历史,并且对该地区存在的一些有争议的问题,如阿什火山1951年5月27日喷发事件的报道、大黑山火山的喷发方式、高台山火山的存在与否等问题提供了野外证据。

From May 4 to May 30,2011,a field exploration on Ashikule Basin in Western Kunlun mountain area was conducted by the research team from Institute of Geology,China Earthquake Administration and Xinjiang Earthquake Administration.This work is financially supported by the special fund for China earthquake research project ＂The comprehensive scientific exploration of Yutian MS 7.3 earthquake in 2008 and Ashikule volcano group＂.Through detailed field survey on geological and geomopholoical features of Ashikule volcano group,which is one of the volcanic plateaus at the highest altitude（about 5,000m）in the world,we found out the total number of volcanoes,the eruption type and structural parameters,and the active history of the volcano group.Our studies have provided field evidences for resolving the controversies existing in the past,such as the authenticity of the news report about the eruption event on May 27,1951,the eruption pattern of Daheishan volcano,and the reality of Gaotaishan volcano and etc.
