Abstract:

The discovery basalte and rhyolite intercalated with terrigenous sediments of Dong Trau formation in the Nhu Xuan and Thuong Xuan district, Thanh Hoa province. It is considered that basalte and rhyolite in this formation form bimodal association basalte- rhyolite. According to the major and trace element analysis studies association characterizes tholeiitic and calc - alkaline series. U-Pb zircon isotopic age (LA-ICP-MS) of dacite and rhyolite: 228Ma; 141Ma and 245Ma.
