Lithospheric structure and evolution of the metamorphic basement of Sri Lanka and comparisons with southern India: Gondwana amalgamation in the Neoproterozoic

这是波茨坦地质研究中心、慕尼黑、科隆美因茨大学、康提基础研究所和斯里兰卡科伦坡地质调查局的科学家之间的合作研究项目，是ilp倡议传奇的一部分。目的是阐明斯里兰卡西部和东部变质基底的构造、地质年代学和同位素演化，从而有助于解释该岛的东西地震剖面。我们的目标是对Wanni和Vijayan杂岩进行综合的地震、构造、年代学和地球化学研究，以揭示现今的地壳结构、它们与邻近地形的边界以及它们的地球动力学演化。比较斯里兰卡和印度南部的高等级地形应该能揭示它们是否属于同一地壳实体。实地和实验室工作将由参与小组共同进行。该项目的一个主要目标是加强康提和科伦坡参与机构的研究潜力，并向斯里兰卡转让现代研究技术。

This is a collaborative research project between scientists of the Geoforschungszentrum Potsdam, the Universities of Mainz, Munich, Cologne, the Institute of Fundamental Studies, Kandy, and the Geological Survey in Colombo, Sri Lanka, as part of the ILP-Initiative LEGENDS. The aim is to elucidate the tectonic, geochronologic, and isotopic evolution of the metamorphic basement in West and East Sri Lanka and thereby contribute to the interpretation of an East-West seismic profile acrfoss ther island. We aim at an integrated seismic, structural, geochronological, and geochemical study of rocks of the Wanni and Vijayan Complexes in order to reveal the present crustal structure, their boundaries with adjacent terrains and their geodynamic evolution. Comparisons between the high-grade terrains in Sri Lanka and southern India should reveal whether they belong to the samer crustal entity or not. Field and laboratory work will be carried out jointly by the participating groups. A major aims of the project is to strengthen the research potential of the participating institutions in Kandy and Colombo, and to transfer modern research technology to Sri Lanka.
