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).

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:阿尔泰式是亚洲洋背景上形成的生代对流地幔物质,热输入和上地壳混合为主的方式;东昆仑式是元代造山带TTG陆壳背景基础上生代—早中生代对流地幔物质和热输入,改造元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的生长方式。

北京城西南部是蓟城的发源地,当地原始地貌景观形成于全新世,它受到金沟河和漯水的共同影响,当蓟城建立后,它受到人类城市活动的强烈影响,不断进行着人为剥蚀与人为堆积的双重过程,并受到洪水的侵蚀,蓟城的地貌景观及岩土沉积环境的演化正是在自然与人为的双重作用下实现的。

Taking for example the salt rhythms of the Qianjiang Formation in the Qianjiang Sag of the Jianghan Basin (which is a typical Paleogene saline lacustrine basin in eastern China), through a detailed study on cores, the authors have determined for the first time the Ⅳ-order salt rhythm based on Ⅰ-,Ⅱ-and Ⅲ-order salt rhythms which were determined previously and got to know that the sedimentary process following the sequence of desalinizing→salinizing and crystallization of salt minerals from halite rock→(mud-bearing) glauberite rock→dolomite-bearing mudstone (mud-bearing doloston)→mudstone→doloston→glauberite rock→halite rock. The authors also analyzed the Ⅳ-order salt rhythm and the correspondence between its sedimentary records and the fluctuation of the palaeosalinity of waters and the short-scale (0.05~1.0 ka duration) change of dry-moist palaeoclimate.

本文以我国东部独具特色的近纪盐湖盆地-江汉盆地的潜江凹陷潜江组盐韵律为例,通过对王平1、王云10-6、王80-2等3口井连续取心段的精细研究,在前人划分Ⅰ、Ⅱ、Ⅲ级盐韵律的基础上,首次划分出组成含盐层系基础韵律单元-Ⅳ级盐韵律,弄清了它的沉积过程基本遵循从石盐岩→钙芒硝岩→含白云石泥岩→泥岩→白云岩→钙芒硝岩→石盐岩的淡化-咸化序列和盐类矿物的析出顺序;解析了Ⅳ级盐韵律及其沉积组合记录与水体盐度波动和短尺度(0.05~1.0 ka)气候干湿变化之间的对应关系。

And whether is it necessary to redefine the geotectonic pattern in southern China? In 1993, the authors discovered firstly the late Paleozoic radiolarian silicalite in the "Shuangqiaoshan Group", which, as we know, is a block within the ophiolitic mélange. In 1996, the authors discovered again the late Paleozoic fossils in the other rocks of "Shuangqiaoshan Group" and "Zhitang Formation" of Lower Sinian Series in the ophiolitic mélange. At the same time, the authors discovered firstly the early Paleozoic chitinozoa fossils.
