造山带地层的复杂性造成造山带地层研究的困难。史密斯地层和非史密斯地层并存 ,特别是非史密斯地层学尚不完善 ,因而造山带地层研究中往往会出现一些概念和认识上的混乱 :混杂岩是不是地层 ?属不属于地层学研究的范围 ?根据某些新的发现对以往建立的一些岩石地单位的“解体”和“重新命名”是否合适 ?有时甚至会对一个地层单位的真正涵义发生误解。本文根据国际地层指南和中国地层指南所给出的地层划分、命名的原则、方法 ,试就这些问题进行探讨。
The complexity of the orogenic strata causes difficulty in the study of the orogenic belt. The coexistence of the Smith strata and the non-Smith strata, especially the non-Smith stratigraphy, is still imperfect. Therefore, there are often some confusions and cognitions in the research of stratigraphic orogenic belt: Is the melange the strata? Does not belong to the stratigraphic study scope? According to Is some of the new discoveries appropriate for the “disintegration” and “renaming” of some of the previously established lithosphere units and sometimes misunderstood the true meaning of a stratigraphic unit? Based on the principles and methods of stratigraphic division and nomenclature given by the International Stratigraphy Guide and China Stratigraphy Guideline, this paper attempts to discuss these issues.
