Study reveals petrogenesis and geodynamic processes of NW Pacific seamount lavas

A study led by Drs. Xun Wei and Xue-Fa Shi from the First Institute of Oceanography, Ministry of Natural Resources, China presents 40Ar-39Ar age, geochemical, and Sr-Nd-Pb-Hf isotopic data of lavas from Hemler, Vlinder, and Il'ichev seamounts in the West Pacific. The research elucidates their petrogenesis and geodynamic processes.
