前言随着构造地质学的发展,以前被笼统地称作断层角砾岩者,发现有些角砾无角,而且有一定的磨圆和分选,于是便出现了构造砾石或构造卵石等名称。地质力学工作在我国开展以来,从各个角度对结构面力学性质的鉴定作了理论上的探讨和大量的实际工作,线理、片理、透镜体、劈理、节理等都是经常被描述的构造形迹。而断裂带内广泛发育的构造 Preface With the development of tectonic geology, previously generally referred to as faulted breccias, some of the breccia were found to have no horns and some rounding and sorting. Thus, the names of structural gravels or pebbles were found. Geomechanics work has been carried out in our country, from all angles on the mechanical properties of the structural surface of the identification made a theoretical discussion and a lot of practical work, the line, film theory, lens body, cleavage, joint, etc. are often described Structure traces. In the fault zone widely developed structure
