Overview in situ U - Pb isotopic dating method on cassiterite. Application to determine for Sn - W mineralization age of the Lung Muoi deposit in the Pia Oac region, Cao Bang province

Abstract

In recent years, the U - Pb isotopic dating method for cassiterite minerals has been used by many scientists around the world in the field of mining and mineral research. This paper presents an overview of the history, development and results achieved using this dating method in the field of mining and mineral research in the world. The LA - ICP - MS U - Pb isotopic dating method for cassiterite minerals was used at the Lung Muoi Sn - W deposit in Pia Oac region, Cao Bang province. The result of LA - ICP - MS U - Pb cassiterite isotopic dating shows the Sn - W mineralization in the Lung Muoi deposit crystallized at 88 Ma. The new age results in this paper are very consistent with the previously published results of the Pia Oac granite.
