脆性微观构造学研究的目的是运用中型断裂分析技术来阐明构造问题。术语“中型”(Mesoscale)系沿用Turner和Weiss(1963)的定义,即指尺度从不足一厘米到数厘米的构造,同时它们可以在单个不连续的露头上分辨出来。本文涉及的构造包括中型断裂、剪切带、雁形裂隙、扭折带、裂缝、岩脉以及压溶条纹 The purpose of the study of brittle microstructure is to use medium-sized fracture analysis techniques to elucidate the structural problems. The term “Mesoscale” follows the definition of Turner and Weiss (1963), that is, structures that range from less than a centimeter to a few centimeters in size while they are distinguished on a single, discontinuous outcrop. The structures involved in this paper include medium-sized faults, shear zones, geodesic fractures, kink bands, fractures, dikes and dimples
