Abstract
This report is to report the first year result of a three-year research project
that belongs to the joint CREATE (I)project.In the first year,through collaboration
with Vietnamese and Chinese colleagues,we have investigated and collected late
Paleogene highly potassic igneous rocks from NW Vietnam,Yunnan and eastern Tibet.
These rocks have been dated by Ar-Ar method and petrochemically determined for their
major and trace element and Sr-Nd isotopic compositions.The results have been
presented in several scientific meetings and international journals including one
article published in Nature (August 20,1998).In the second year,the project was
focusing on studying the Paleo-Tethyan ophiolites from the Song Ma area (NW Vietnam)
and Shuanggou,south of the ASRR (Yunnan).This work led us to be tter understand the
Indosinian Orogeny and the evolution of Paleo-Tethys.The new results will be submitted shortly to international journals for publication.
