劈理现象的研究从D.沙尔普开始,已有百余年的历史。关于劈理形象的描述、分类与成因方面的一些基本看法,在本世纪初期及更早一些时候就提出来了(Sorby H. C. 1856; Becker G. 1904; LeithC. K. 1905; Becke F. 1913)。以后,仍有不少构造地质工作者继续不断地进行劈理的研究,提出一些补充资料和分类与成因的看法(如Sander B. 1930; Closs E. 1947; Hoeppener R. 1955; de Sitter L.U. 1956; Knill J. K. 1960; Gonzalez-Bonorino F. 1960; Turner F. J. & Weiss L. E. 1963)。所以如此,我们认为有两点原因:(1)劈理研究具有工作方法上的意义。劈理是一种基本的、普遍的构造变形现象,通过对它的野外观察、素描、测量以及室內镜下观察和统计,可以提供出一套基本的构造分析
The study of cleavage has been more than one hundred years since D. Sharpe. Some of the basic ideas about the description, classification, and genesis of the image of cleavage were proposed earlier in the century and earlier (Sorby HC 1856; Becker G. 1904; Leith C. K. 1905; Becke F. 1913) . Since then, there are still many structural geologists who continue to conduct cleavage research and put forward some supplementary information and the classification and causes (eg Sander B. 1930; Closs E. 1947; Hoeppener R. 1955; de Sitter LU 1956 ; Knill JK 1960; Gonzalez-Bonorino F. 1960; Turner FJ & Weiss LE 1963). So, we think there are two reasons: (1) Cleft research has a working methodological significance. Cleavage is a fundamental and widespread tectonic deformation that provides a basic tectonic analysis through its field observations, sketches, measurements, and microscopic observations and statistics
