早前寒武纪变质地层学研究的回顾与思考

主要论述了与早前寒武纪变质地层（学）有关的8个方面的问题：早前寒武纪变质地层的研究概况；早前寒武纪变质地层的复杂性和研究难度；早前寒武纪变质地层研究的思路和工作方法；早前寒武纪变质岩石地层单位岩群、岩组和杂岩的划分问题；重要区域性不整合的研究；鉴定变质地层的原岩类型、岩石性质和恢复古环境；正确区分变质地层和TTG岩系以及其他变质深成岩；变质地层时代的确定。另外，对今后的研究工作提出了3项建议。

Review and deliberation of the researches on Early Precambrian metamorphic stratigraphy

Eight aspects related to the study of Early Precambrian metamorphic stratigraphy are dealt with in this paper: general situation of the study; complexity of the stratigraphy and difficulties of the study; thoughts and methods of the study; division of rock suite, rock group and complex rock; researches on important regional discordances; types and characteristics of protolith and recovery of palaeoenvironment; correct differentiation of the metamorphic strata, TTG rock system and other metamorphic plutonic rocks; determination of the ages of the metamorphic strata. In addition, three suggestions are put forward for future work.
