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.

这是波茨坦地质研究中心、美因茨大学、慕尼黑大学、科隆大学、康提基础研究所和斯里兰卡科隆博地质调查局的科学家之间的一个合作研究项目，是ILP倡议LEGENDS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、年代学和同位素演化，从而有助于解释跨越该岛的东西向地震剖面。我们的目标是综合地震，结构，地质年代学和地球化学研究的Wanni和Vijayan复杂的岩石，以揭示目前的地壳结构，其边界与邻近的地形和地球动力学演化。比较斯里兰卡和印度南部的高等级地形，可以揭示它们是否属于同一地壳实体。实地和实验室工作将由各参与小组联合进行。该项目的一个主要目的是加强康提和科隆博参与机构的研究潜力，并向斯里兰卡转让现代研究技术。
