Abstract:

The Chu Lai - Ba To Complexes is in Kon Tum Massif. This is a large area with long evolutionary and complex history, were recorded many geological, magmatic, tectonic events and associated with the valuable minerals. In the framework of this article, Zircons from the Chu Lai - Ba To Complexes in Bình Nguyên - Quảng Ngãi (QN.05) had the LA - ICP - MS U - Pb analyses clustered at 434.58 ± 1.0 Ma. The age of the Chu Lai - Ba Complexes showing that it is similar with the age of Tra Bong and Dai Loc Complexes in the west and the north - west of region. The similar in the age and the type of granite type S may relative to volcanic arc in the region. It meant that Chu Lai - Ba to Complexes is the result of rigional volcanic arc in the middle of Indochina in Paleozoi era. It might be the result of the formation of Tam Ky - Phuoc son shear zone like other research before. In large scale, it could be the result of colition between indochina block and southchina block
