摘要
本文研究了阿尔金断裂东北段大鄂博头—宽滩山约340多公里范围内九个剖面的断层微量气体R_n、H_2、CO_2、Hg的浓度沿断裂的变化特征,根据微量气体的浓度变化对断层作了分段,並对断层的现今活动性进行了讨论。指出,大鄂博头—三个泉为现今强烈活动段;三个泉—昌马车路口为活动段;昌马车路口—宽滩山为相对稳定段。在此基础上对阿尔金断裂东北段未来强震作了初步预测。
This paper deals with the features of concentration variation of the microgases (Rn, H_2, CO_2, Hg) along the northeaste(?)n segment of Aerjin fault, on which we do 10 plus profiles from Annanba to Kuan tanshan about 400 plus km. The fault is segmented a(?)cording to the concentration variation of microgas and the recent fault activity is also discussed. It is suggested that it is a obvious segment of the recent activity from Annanba to Sangequan; it is general from Sangequan to Chelukou of Changma; it is relatively stable from Chelukou of Changma to Kuantanshan. Finally, the preliminary strong earthquake forecast on the northeastern segment of Aerjin fault is made.
