U-Pb isotopic age in zircon of the granitoid rocks at cam mountain – An Giang province

Abstract

Results of analyzing U – Pb isotopic age for zircon in biotite granite, fine granite, monzodiorite, syenite diorite are 88±1.7 Ma, 86±1.7 Ma, 108±0.63 Ma 101±1.5 Ma,. These confirmed that they are Cretaceous age.

Through this paper, many thanks to Professor Tony Crawford and Master Dinh Quang Sang (Tasmania University, Australia) for helping us to analyze these isotopic samples.
