摘要/Abstract

摘要： 高吉山火山位于大兴安岭火山岩带上，属白音高老组地层，根据“火山构造—火山岩相—火山地层”三重填图法对高吉山火山进行了研究。结果表明：高吉山火山发育的岩石类型主要为流纹质晶屑凝灰岩、流纹质熔结凝灰岩、流纹岩、黒曜岩等；岩相主要有空落相、溢流相、火山碎屑流相、潜火山岩相、侵出相以及蒸汽—岩浆爆发相，局部地区见少量喷发沉积相。综合分析认为高吉山火山火山类型为破火山，破火山活动主要经历了4个阶段，即破火山爆发阶段、火山塌陷阶段、破火山复活阶段以及构造破坏及剥蚀阶段。

Abstract: AbstractGaojishan volcanic locates at Great Xing'an Range volcanic belt,Gaojishan volcanic is studied with "volcanic constructionlithologic rock faciesvolcanic sequence" mapping method.The study results show that the rock types developed in the Gaoji Mountain volcano are mainly rhyolitic crystal tuff,rhyolitic ignimbrite,rhyolite,black obsidian,etc..Lithofacies are mainly lacustrine accumulation phase,overflow phase,pyroclastic flow phase,transgressive phase,subvolcanic rock phase and steammagma explosion phase,and eruption sedimentary facies can be seen locally.According to the comprehensive analysis,the volcanic type of Gaojishan volcanic is caldera,and volcanic activity mainly experienced four stages,such as volcanic eruption stage,volcanic collapse stage,volcanic revival stage and tectonic destruction and denudation stage.

Key words: Gaojishan volcano,Lithological type,Lithofacies,Tectonic evolution
