A new paper availible on line now in Gondwana Research looking at the petrogenesis of Mesozoic lavas from Monglia combines Ar-Ar dating, major and trace element chemistry, and Sr-Nd-Pb-Hf isotopic data. The combination of data sets on several different sets of lavas allowed several tectonic models to be proposed and combining the new models proposed with previsou evidence supports the sugestion that the Mongol-Okhotsk Ocean closed with double-sided subduction....
