Abstract
The granitoid formations of Hai Van massif with petrographical components consist of biotite granite, two mica granite. Chemical components of rocks are: SiO2: 69,34=73,92%, Na2O+KO: 6,11-8,11%, K2O/Na20>1. Content of Ba, Sr is low but Rb is higher. From results of Nd-Sm isotopic analysic shows that they are nearly same with stable crust material. Age of source region formation is 1,33 billion years (model of homogeneous chondrite source region), or 1,95 billion years (model of poor mantle source region). U-Pb isotopic age: 241,9+ 2 and 241,4+2.1 million years.
