Field investigations of granulite-facies metasedimentary and granitoid assemblages in the Madurai and Trivandrum Blocks of southern India, followed by zircon dating, petrological characterisation as well as Sm-Nd and Hf-in-zircon isotopic characteristics with the aim to establish the age and petrogenesis of these rocks and compare them with similar associations in Sri Lanka. The overall purpose is to correlate major crustal units between southern India and Sri Lanka for the first time and to reconstruct the amalgamation of East Gondwana.

在印度南部的Madurai和Trivandrum块中对颗粒类面和花岗岩组合的现场调查，其次是锆石约会，岩石学表征以及SM-ND和HF-In-Zircon同位素同位素特征，旨在建立年龄和质量的质量。在这些岩石中，将它们与斯里兰卡的类似关联进行了比较。总体目的是首次将印度南部和斯里兰卡南部之间的主要地壳单元关联，并重建东冈瓦纳的融合。
