裂隙岩相学研究——以美国加州深钻岩心的扫描电镜观察为例

STUDY ON CRACK PETROGRAPHY——Evidence from the SEM Observation of the Rock Core from a Deep Drill Hole in California, U. S. A.

籍助于微束技术,进行观察研究的裂隙岩相学是一门新兴学科。作者利用美国加州大陆地壳深钻研究项目中采集的定向岩心标本所做的大量扫描电镜观察作为实例,从研究宗旨、样品制备、电镜测定和结果分析等几方面对裂隙岩相学研究予以系统阐述。

Crack petrography is a burgeoning branch of geology dealing with the observation and study of rocks by means of the micro-beam technique. The authors have devoted much SEM observation and study to the oriented core samples which were collected by the geologists of the project 'Deep Observation and Sampling of the Earth's Continental Crust (DOSECC)' in California, the united States. A systematic description is made on crack petrography in terms of the purpose of the study, sample preparation, determination by the electron microscope and result analysis.
