The results of systematic petrological-geochemical study of the Early Tertiary basalt from a drill hole in the East China Sea show its tholeiitic nature in major chemistry and slight enrichment in REE, The primitive-like Sr isotopes and negative Nd value suggest that the mantle source is dominated by the EMI-LOMU component which is first observed in South China.The overall geochemical pattern implies the dominant role of the mixing processes between EMI and DM components in the source of Early Tertiary basalts...

The results of systematic petrological-geochemical study of the Early Tertiary basalt from a drill hole in the East China Sea show its tholeiitic nature in major chemistry and slight enrichment in REE, The primitive-like Sr isotopes and negative Nd value suggest that the mantle source is dominated by the EMI-LOMU component which is first observed in South China.The overall geochemical pattern implies the dominant role of the mixing processes between EMI and DM components in the source of Early Tertiary basalts and the perservation of the ancient basement in the region.

本文首次报道东海陆架拗陷带早第三纪玄武岩的发现及邻区有关玄武岩同位素体系分析结果。初步研究表明东海玄武岩为晚渐新世喷发产物,源自与岩石圈有亲缘关系的富集地幔,EMI-LOMU端元在其源区中起主导作用,其深部很可能具古老大陆基底,这一推论为研究华南地区构造演化提供了新的制约。

A systematic Sm-Nd isotopic analysis is carried out for Permian to Meso-proterozoic sediments from the southern margin of the Yangtze Block, SE China.A coherent secular variation of tDM model ages is identified in fine-grained elastic sediments from these sediments.The Meso-proterozoic sediments with stratigraphic ages of≈1. 6 Ga to 1.0 Ga have approximately constant tDM ages of ≈1.8 Ga. In the early Neo-protero-zoic(900-770 Ma),there is a dramatic decrease in tDM ages from ≈1.8 Ga to≈1.3 Ga., In the late Sinian,through...

A systematic Sm-Nd isotopic analysis is carried out for Permian to Meso-proterozoic sediments from the southern margin of the Yangtze Block, SE China.A coherent secular variation of tDM model ages is identified in fine-grained elastic sediments from these sediments.The Meso-proterozoic sediments with stratigraphic ages of≈1. 6 Ga to 1.0 Ga have approximately constant tDM ages of ≈1.8 Ga. In the early Neo-protero-zoic(900-770 Ma),there is a dramatic decrease in tDM ages from ≈1.8 Ga to≈1.3 Ga., In the late Sinian,through to Permian sediments, the tDM ages increase again to≈1.8 Ga.This pronounced decrease in tDM ages inthe early Neo-proterozoic sediments require a large increase in the proportion of juvenile mantle-derived materials from the provinance of the southern margin of the Yangtze Block. The Nd isotopic results presented here enable new constraints to be placed on the tectonic evolution in SE China.The integrated geological, geochemical and chronological constraints on the Banxi rocks suggest that the Banxi Group is most likely part of the normal Proterozioic stratigraphic section in the southern margin of the Yangtze Block. The Neo-Proterozoic collision between the Yangtze and Huanan Blocks resulted in the "Nd isotopic shift" in the sediments.

本文系统分析了扬子块体南缘中元古代到二叠纪各个时代地层中泥质沉积岩的Sm-Nd同位素组成。中元古代(1.6~1.OGa)沉积岩具有一致的Nd模式年龄(tDM)(≈1.8Ga);晚元古代早期(0.9~0.77Ga)沉积岩的tDM年龄从≈1.8Ga急剧降低至。1.3Ga;震旦纪晚期到二叠纪(0.66~0.27Ga)沉积岩的tDM年龄又恢复到大约1.8Ga。晚元古代早期沉积岩tDM年龄的显著降低,表明这个时期扬子南缘的沉积物源区加入了大量新的幔源物质。沉积岩的Nd同位素结果对中国东南部的大地构造演化提供了新的制约。地质、地球化学和年代学资料均表明扬子南缘的板溪群是一正常的元古代地层单位。华南一扬子晚元古代(晋宁期)碰撞造山运动导致了上述沉积岩的“Nd同位素漂移”。

The development and changes in Sino-African relationship is closely linked to those in international setup and those in the trends in China and Africa.

The development and changes in Sino-African relationship is closely linked to those in international setup and those in the trends in China and Africa. Under notable cold-war setup lasting nearly half a century since the WWII, China has successfully adopted foreign strategies such as “leaning to one side", “two-line struggle" and “one-line struggle" according to the relationship with the US and Soviet Union during different times. The Sino-African relationship also experienced the changes in the reinforcement of political benefits and ideology from the 1950s to the 1970s and weakening ideology and valuing economic benefits in the 1980s. After the cold war, the transition setup of “one super and many powers" has brought in certain new restriction for the development of Sino-African relationship; and, on the other hand, it has also provided with new political foundation for the development of Sino-African relationship. Looking at the irresistible historical trend of multi-polarized international setup, the reinforcement of Sino-African relationship is also beneficial to the multi-polarization of international setup and to improve our international influence. Under the multi-polarization setup, Sino- African relationship will enter a new stable, healthy and self-developing era.

中非关系的发展变化与国际格局的转换以及中国、非洲双方各自形势的发展变化紧密相连。在二战后长达近半个世纪的冷战大格局下 ,中国依据不同时期与美苏关系的远近先后采取了“一边倒”、“两条线”和“一条线”的外交战略 ,中非关系因而也经历了从 2 0世纪 50~ 70年代末强化政治利益和意识形态色彩到 80年代淡化意识形态、重视经济利益的转变。冷战后“一超多强”的过渡性格局既给中非关系的发展带来了一些新的制约因素 ,同时也为中非关系的发展提供了新的政治基础。从长远看 ,国际格局的多极化不可抗拒。中非关系的加强有利于推进国际格局的多极化 ,提高我国的国际影响力。中非关系在多极化格局下也将步入一个稳定、健康、自主发展的新时代。
