确定变质岩区褶皱构造形态的几种方法及其理论分析

本文根据作者多年研究和实践,提出确定变质岩区褶皱构造形态的3种技术和方法:1.微片石法,2.钩状褶皱法,3.构造透镜体法。它们的理论依据是构造置换。这些方法无论在实际上,还是在理论上都是能成立的。应用这些方法能获得较好的效果。     

THREE METHODS FOR DETERMINING STRUCTURAL SHAPES OF FOLDS IN THE METAMORPHIC ROCK REGION AND THEIR THEORETICAL FOUNDATION

Based on the results of research work and practices of the author, three kinds of methods and techniques for determining the fold shapes in the metamorphic rock region are advanced: (ⅰ) the microschist method, (ⅱ) the hook fold method and (ⅲ) the structural lenticular method. The theoretical foundation of these methods is structural transposition. The methods and techniques are successful both in practical and theoretical senses. We have gained fairly good effects by utilizing these methods.
