摘要
变形岩石中普遍存在有不同程度的体积损耗。本文介绍了这方面的研究历史、现状及新进展，总结了三类体积损耗的估算方法．第一类方法是直接对比未变形的和已变形的标志体的体积；第二类方法是基于有限应变类型变化的分析对比；第三类方法是依据变形前后物质成分的变化。
Volume loss occurs widely within deformedl rocks.This paper introduces the development of the studyon volume loss and three methods of volume loss estimation.It is important to determine volume loss in analysis of finite strain state.calculation of tectonic strain,and understanding of initial state of deformed rocks andthe relationship beteen deformation and composition change of deformed rocks.
