"Dongwu Movement" was named by Professor Li Siguang (1931) on thebasis of the angular unconformity between the Qixia Formation and Longtancoal series in the eastern suburb of Nanjing, i.e., in Qinglong Mount (Guan-tang) and along Shizi Mount near Longtan. It is taken over by the vast num-bers of Chinese geologists in the past 50 years.

"Dongwu Movement" was named by Professor Li Siguang (1931) on thebasis of the angular unconformity between the Qixia Formation and Longtancoal series in the eastern suburb of Nanjing, i.e., in Qinglong Mount (Guan-tang) and along Shizi Mount near Longtan. It is taken over by the vast num-bers of Chinese geologists in the past 50 years. In recent years, however, theexistance of "Dongwu Movement" has been disputed along with the deepeningresearch and the accumulation of large amount of new data. Based on the ana-lysis by combining histories of sedimentary formation with that of taphrogenicdevelopment, the autbors prove that "Dongwu Movement" in South CLinaterrain is inexistance. The disconformity between the Lower and Upper Permianin the Yangzi Terrain may be named as "Chuanqian Movement". This move-ment occured from Middle-Late Maokou in the Early Permian to Early Longtan ofthe Late Permian. It was one episode of the Variscan taplirogenic cycle thatbappened in the Yangzi Terrain. While the crust was on the mechanism of pullingapart.the Yangzi and South China Terrains underwent repeated and wavelike til-ting up and down,just like a balance during the Permian, thus resulting in theraising up deformation all over Yangzi Terrain. This movement did not onlyshow differential elevation and subsidence between blocks in the terrain, but al-so resulted in basalt eruption and its mineralization in the rhombic rift-subsidedbasin. Therefore, the negation of "Dongwu Movement" and the new idea on"Chuanqian Movement" may be helpful in exploring the pattern of crust mo-vement in Variscan taphrogenic cycle.

作者根据近年获得的大量新资料,用沉积建造史与地裂运动发展史相结合的分析方法,论证了华南地体区内“东吴运动”之不存在;而将扬子地体区内,存在于上、下二叠统之间的假整合现象,厘称为“川黔运动”。后者发生于早二叠世茅口中晚期至晚二叠世龙潭早期,是华力西地裂旋回期的一次构造运动幕。

Oncoids occur very abundantly in the upper Carboniferous of Chuan-shan formation from Yangtze terraue. Based on the study of 29 profiles and detailed identification of 803 thin sections,their characteristics,typcs,dcpositional environment and genetical mechanism of oncoids have been studied and discussed.

扬子地体上石炭统船山组内核形石极为丰富,按照内部结构和构造可分五种纹层类型、二种壳层构造和四种核心结构。核形石并非过去所认为的单一的“葛万藻核形石”,而可以根据形态和壳层中的生物组合划分为十种基本类型,其沉积环境有滩、潮下低能带和泻湖等。 石炭纪晚期,由于全球的气候发生强烈分异,从而在低纬度地区产生大量分泌粘液的缠绕生物(藻类为主),核形石就是由这种缠绕生物捕集沉积质点围绕核心而成,其形成过程有四个阶段—核心形成阶段,壳层形成阶段、沉积搬运阶段和成岩后生阶段。 在成岩后生阶段,核形石岩可以产生大量的核间和核内溶孔,这对于油气、矿液的储集和运移是十分有利的。

The contents of precious and base metals in Mesozoic non-marine volcanics and cryptovolcanics from northeastern Jiangxi area are as follows: Au 0.0138 and 0.0803 ppm, Ag 1.57 and 4.74 ppm, Cu 22.8 and 46.1 ppm, Pb 132 and 192.7 ppm and Zn 132 and 192.7 ppm and Zn 132 and 181.1 ppm respectively. The average values of Au, Ag, Cu, Pb and Zn are higher in cryptovolcanics than in volcanics. In time, the highest values occur in Ⅰ , Ⅱ cycles of volcanicactivity, while in spatial bistribution higher values are found...

The contents of precious and base metals in Mesozoic non-marine volcanics and cryptovolcanics from northeastern Jiangxi area are as follows: Au 0.0138 and 0.0803 ppm, Ag 1.57 and 4.74 ppm, Cu 22.8 and 46.1 ppm, Pb 132 and 192.7 ppm and Zn 132 and 192.7 ppm and Zn 132 and 181.1 ppm respectively. The average values of Au, Ag, Cu, Pb and Zn are higher in cryptovolcanics than in volcanics. In time, the highest values occur in Ⅰ , Ⅱ cycles of volcanicactivity, while in spatial bistribution higher values are found in 1,2,4, 7, 8, 9 volcanics areas. Lithologically, intermediate-acid rocks have higher values than the other rock types, whereas of the same rock type, those ralatcd to ore arc higher in metal content by a factor 51 to 4 than the barren rock.

本文论述了赣东北中生代火山岩中微量元素与稀土元素在不同岩性岩相及时空上的分布规律:潜火山岩中Au、Ag、Cu、Pb、Zn平均含量高于火山岩,尤以中酸性岩中较高,Ⅰ,Ⅱ旋回高于其他旋回。稀土元素由Ⅰ向Ⅱ旋回,由扬子地体向华夏地体,由爆发相向溢流相、潜火山岩相,由偏基性向中酸性岩演化;稀土配分模式是“L”型,火山岩物质来源于下地壳的部分熔融。
