鲜水河活动断裂带航磁异常特征

鲜水河断裂带的构造几何特征及其地质背景是进一步研究鲜水河断裂带的孕震性的重要基础资料。从收集、处理、解释航磁资料着手，在前人的工作基础上，进一步分析研究了鲜水河断裂带的几何形态特征及鲜水河地区的地质背景，特别是深部构造情况，揭示了断裂带的几何形态结构特征与深部构造之间的联系，并发现了一个可能与孕震有关的环形构造（岩体）。

THE STUDY OF STRUCTURAL ENVIRONMENT OF XIANSHUIHE ACTIVE FAULT ZONE AND NEIGHBOURING REGION USING AEROMAGETIC DATA

The structural environment and geometric features are important basic data for study ofearthquake preparation in the Xianshuihe active fault zone． This paper analyses the structural andgeometric features of Xianshuihe active fault by collecting，processing and explaining aeromagnet-ic data and data from pioneer′s works ，studies the structural environment，especially the deep-seated structure of Xianshuihe active fault， reveals the relation between the structural geometric features and the deep-seated structure，and discovers an circular magnetic body related to earth-quake
