浅述五大连池火山区浅层气体钍、氡与断裂构造和火山活动的关系

在五大连池火山区流体化学研究原有工作的基础上，对火山群的重要区段开展了野外踏勘、气体普查，特别是用放射性气体测量方法对火烧山、老黑山、笔架山、药泉山等火山区进行了Tn、Rn测量。通过大量实测资料，分析和研究了Tn、Rn等气体和火山、火山活动、断裂构造、断裂活动性及其他地质条件的关系，初步查明了五大连池火山区的气体组成特征、分布和形成规律，对地下主要气体的成因、气体和火山构造活动及其它地质条件的关系进行了初步探讨，并提出了对五大连池火山区气体观测的初步设想和建议。

RELATIONSHIP OF GAS Th, Rn TO FRACTURE STRUCTURE AND VOLCANIC ACTIVITY IN WUDALIANCHI VOLCANIC AREA

Base on the research of liquid chemistry in Wudalianchi volcanic area ,field exploration and gas check were done in important region of volcano group,especially by means of gas Th,Rn was measured in Huoshao mountain,Laohei mountain,Bijia mountain and Yaoquan mountain.The relationship of gas Th,Rn to volcano,volcanic activity,fracture stracture,fracture activity and other geologic condition were analysed and studied by a lot of materials.The gas component characteristic,distribution and form were checked out and the reason of gas creation and the relationship between gas and volcanic structural activity,other geological condition were studied.The suggestion about gas observation in Wudalianchi volcanic area were pointed out.
