近20年来,电子显微镜在地球科学上获得越来越广泛应用.许多学者对风成、冰川、水下以及表土风化等环境中的石英碎屑做了较详细的研究。随着地震地质学的发展,人们对现代活动断层的断层产物研究给予极大的重视。利用电子显微镜来揭示活动断层产物中的石英碎砾显微构造特征和意义就更显重要了。本文利用扫描电镜(SEM)观测研究了活断层中的石英碎砾,并指出其中反映活断层成因环境的典型显微构造特征。
In the past 20 years, electron microscopes have been more and more widely used in geosciences, and many scholars have studied in detail the quartz crumbs in wind, glaciers, underwater and topsoil weathering. With the development of seismic geology, great attention has been paid to the study of the fault products of modern active faults. It is even more important to use electron microscopy to reveal the microscopic structural features and significance of quartz gravels in active fault products. In this paper, the quartz crushed gravel in the active fault was observed by scanning electron microscope (SEM), and the typical microstructural features reflecting the genesis of the active fault were pointed out.
