摘要:
提要:中国大陆造山带花岗岩可分为东西两个区,西区的中亚造山带、秦祁昆造山带和青藏高原冈底斯造山带为与大洋发育有关的造山带花岗岩,东区主体的东北、华北和华南是形成于中国大陆拼合之后的燕山期造山带花岗岩。根据不同造山带花岗岩的形成背景、地质地球化学特征差异,以阿尔泰、东昆仑、华北燕山、东北和南岭造山带花岗岩为例讨论花岗岩与大陆地壳生长的关系,区分出中国大陆的5种大陆地壳生长方式:阿尔泰式是古亚洲洋背景上形成的古生代对流地幔物质、热输入和上地壳混合为主的方式;东昆仑式是元古代造山带TTG陆壳背景基础上古生代—早中生代对流地幔物质和热输入,改造元古宙造山带基底的方式;东北式是燕山期中亚造山带背景上对流地幔物质和热输入改造显生宙陆壳的生长方式;燕山式是燕山期对流地幔物质和热输入改造太古宙基底的方式;南岭式燕山期对流地幔输入大陆的是以热为主、物质为辅,大陆地壳生长是以陆壳物质再循环为主(零增长)的生长方式。它们构成中国大陆显生宙地壳生长的基本方式。

Abstract:
Abstract:Orogenic granitoids in the continent of China may fall into the east and west regions. The orogenic granitoids in the west region include the Central Asian orogenic belt, Qinling-Qilian-Kunlun orogenic belt and Gangdise orogenic belt in the Qinghai-Tibet Plateau, which are associated with the development of the ocean, and the orogenic granitoids in the east region, including Northeast China, North China and South China, are Yanshanian orogenic granitoids formed after the assembly of the continent of China. Based on the settings and geological and geochemical characteristics of granitoids of different orogenic belts (exemplified by orogenic granitoids in Altay, East Kunlun, Yanshan in North China, Northeast China and Nanling in South China), the relationships between granitoids and continental crustal growth are discussed, and five modes of continental crustal growth in the continent of China are proposed;they are as follows:(1)the Altay mode of continental growth is that the material and heat of the Paleozoic convertive mantle formed on the background of the Paleo-Asian Ocean were input into the Paleozoic continent and mixed with the materials of the upper crust;(2) the East Kunlun mode is that the basement of the Proterozoic orogenic belt was reworked by the heat input and materials of the Paleozoic-early Mesozoic convective mantle formed on the background of TTG continental crust of the Proterozoic orogenic belt;(3) the Northeast China style is that the Phanerozoic continental crust was reworked by the heat input and materials from the convective mantle formed on the background of the Yanshanian Central Asian orogenic belt;(4) the Yanshan mode is that the Archean basement was reworked by the heat input and materials from the Yanshanian convective mantle;and (5) the Nanling mode is that in South China what was input by the Yanshanian convective mantle into the continent was mainly heat and subordinately materials and the crustal material recycle was the dominant mode for the continental growth (showing zero continental growth). These modes are the basic modes for the Phanerozoic continental growth of the continent of China.
