Among different opinions , the most popular one is that the temporal and spatial distribution and evolution of the gangdise plutonic - volcanic belt are controlled by the northward subduction of the yarlung zangbo oceanic crust and the southward subduction of the bangong - nujiang oceanic crust 在众多的观点中较权威的观点，是冈底斯岩浆带的时空分布与演化受控于雅鲁藏布江洋壳和班公湖-怒江洋壳分别向北向南俯冲。

He spoke in a strange northern accent ; his thoughts being turned inwards upon himself , his eye on his iron charge , hardly perceiving the scenes around him , and caring for them not at all : holding only strictly necessary intercourse with the natives , as if some ancient doom compelled him to wander here against his will in the service of his plutonic master 他说话时带有奇怪的北方口音他心里只管想着自己的心事，他的眼睛只管照看自己的铁机器，而对周围的景物差不多看也不看，毫不关心只有在特别必要的时候，他才和当地人说几句话，仿佛他是在古老的命运的强迫下，不得不违背自己的意愿漂泊到这里，为这个地狱之王一样的主人服务。

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 摘要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。
