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 摘要主要論述了與早前寒武紀變質地層(學)有關的8個方面的問題:早前寒武紀變質地層的研究概況;早前寒武紀變質地層的復雜性和研究難度;早前寒武紀變質地層研究的思路和工作方法;早前寒武紀變質巖石地層單位巖群、巖組和雜巖的劃分問題;重要區域性不整合的研究;鑒定變質地層的原巖類型、巖石性質和恢復古環境;正確區分變質地層和ttg巖系以及其他變質深成巖;變質地層時代的確定。

In terms of their geological and geochemical characteristics as well as the ages of these plutons , these three sub - belts from south to north are interpreted as syn - subductional , syn - collisional and post - collisional plutons respectively . composed of quartz diorite and quartz monzonite , the syn - subduction plutonic rocks are confined only to the south kunlun massif 俯沖期侵入巖僅出露于蛇綠巖帶之南的昆南地塊上,巖性組合為石英閃長巖-石英二長巖,三個主要巖體獲鋯石u - pb年齡值為481ma 、 461ma 、 452ma ,均為奧陶紀。

( 7 ) showing and determining the evidence and timing of the lithophere delamination occurred in qinling orogenic belt . pointing out the gold deposit in xiaoqinling - xiongershan region are mostly formed during indosinian to early - yanshan movement , related to mantle fluid injecting caused by lithosphere delamination and plutonic activity caused by further large - scale tectonic extension 初步闡述了東秦嶺地區的成礦分區和成礦特點,指出小秦嶺一熊耳山地區金礦形成的主要時期是印支一早燕山期,并且與巖石圈拆沉作用所引起的地慢流體活動和之后進一步大規模伸展作用產生的深源巖漿活動密切相關。

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 他說話時帶有奇怪的北方口音他心里只管想著自己的心事,他的眼睛只管照看自己的鐵機器,而對周圍的景物差不多看也不看,毫不關心只有在特別必要的時候,他才和當地人說幾句話,仿佛他是在古老的命運的強迫下,不得不違背自己的意愿漂泊到這里,為這個地獄之王一樣的主人服務。

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 在眾多的觀點中較權威的觀點,是岡底斯巖漿帶的時空分布與演化受控于雅魯藏布江洋殼和班公湖-怒江洋殼分別向北向南俯沖。

Syn - collisional plutonic rocks aie composed of granodiorite and adamellite , which exposed al 由于極度艱苦的工作條件限制,本區研究程度極低。

This belt is bounded on the north by a group of large plutonic masses . 該帶的北部被一群大規模的深成巖體所限。
