| 摘 要： | 区域变质岩区填图工作的关键问题是能否或如何在“地层学”意义上来划分填图单位。鉴于变质岩的构造特殊性,公认应当采用构造-地层方法,但是这里涉及的不单纯是工作程序和具体方法,而且涉及对变质构造特征的理论认识。本文以北京西山浅变质岩系为例,对构造地层学准则进行初探,因为这里可明确建立双重地层系统,便于对比分析。

| Abstract: | Several criteria of mapping in the mctamorphic terranc
have been discussed. The key problem is how to divide the recognizable and mappable lithostratigraphic units, of which the contacts and transposed foliations may usually become the main deformation plane in post-tectonic event. For detailed study of these criteria, we selected an ideal area, West-Hill, Beijing, where the primary sequence can be dated paleontologically. These criteria discussed here are not only involved with special methods for studying and dividing mappable units, but also with some knowledges for understanding structural properties of mctamorphic rockr, theoretically and practically. |
