所谓构造—岩相带是指地壳的某一部分,它在地层和沉积物的发育、构造类型、岩浆活动、变质程度和成矿作用上都有它一定的特点,而与周围地区不同。换句话说,某一构造一岩相带无论在地质构造和地质发育史上均有其特点,而与邻近的构造-岩相带基本上区别开来。根据1956—1958年我们在祁连山的调查研究工作和有关部门的资料,我们对祁连山构造-岩相带的划分提出如下的意见。这种划分主要是在西尼村划分的基础上加以修压和补充而成。它可能还不够精确,有
The so-called tectonic-lithofacies refers to a certain part of the crust, which has certain characteristics in the development of stratum and sediments, structural type, magmatic activity, metamorphism and mineralization, but different from the surrounding areas. In other words, a tectonic-lithofacies belt has its own characteristics both in the history of geological structure and geological development, and is basically distinguished from the adjacent tectonic-lithofacies belt. According to the survey and research conducted in Qilian Mountains from 1956 to 1958 and relevant departments, we put forward the following opinions on the division of tectonic-lithofacies belt in the Qilian Mountains. This division is mainly based on the division of Sini village to be repaired and supplemented. It may not be accurate enough yet
