KEEP TRACK OF WORLD ADVANCES, EXPLORE FOR NEW RESEARCH FIELDS--AN INTRODUCTION TO THE "YADONG-GOLMUD GEOSCIENCE TRANSECT" IN QINGHAI-XIZANG PLATEAU

岩石圈研究计划是继60年代国际上地幔计划和70年代国际地球动力学计划后,于80年代开展的一项大型国际合作研究项目,其全称是“岩石圈的动力学、组成和演化—自然资源和减轻灾害研究纲要”。国际岩石圈研究计划是一个跨地区、跨部门的多学科国际合作研究计划。它运用地质、地球物理和地球化学等多学科手段和方法,从三维空间研究岩石圈的结构、构造、动力学及其形成、演化过程,以满足人类对矿产资源和环境保护的需求,减轻地质灾害,并为板块构造理论发展作出贡献。

'The comprehensive study on Yadong-Golmud Geoscience transect in Qinghai-Xizang Plateau', with eight units taking part in, is charged by the Lithospheric Research Center (Chinese Academy of Geological Sciences). It is a multi-subject project, and also one of 11 Geoscience Transects in China, the Yadong-Golmud transect runs through the Qingha.i-Xizang plateau in North-South direction. This project is designed to deepen the concepts about the structure, tectonics, formation and evolulion of the lithosphere in the Qinghai-Xizang plateau through comprehensive study on geophysical and geological data in that area. This transect has been selected as one of the most important projects in the seventh five-year by the Ministry of Geology and Mineral Resources and it has been financed by the Chinese National Science Foundation.The Project includes 12 items and the following topics are particularly emphasized.★★★1. The Comparison of strata, sedimentary types and their evolutions of different terranes.★★★2. The analysis of rock deformation, metamorphism and their dynamics, occurred at the margin of terranes.★★★3. Magma activities in different terranes and their relation with terrane evolution.★★★4. Regional structure and evolution of different terranes. ★★★5. Paleomagnetic study on the main terranes in the Yadong-Golmud.★★★6. Gravity measurement and interpretation.★★★7. Terrane division and magnetic interpretation along the transect.★★★8. MT measurement on the blank region along transect and interpretation.★★★9. Heat flow measurement and interpretation.★★★10. Re-interpretation on available seismic data.★★★11. Joint interpretation of Various geophysical data and computenized panameters modelling.★★★12. Comprehensive studies on Yadong-Golmud crust, structure of the upper mantle and their evolution.This collected papers only includes the results of intermediate stage and the final results of study will be published in 1990.
