摘要
A recent study published in 20 March issue of the prestigious journal Nature by Dr. LIU Chuanzhou from the CAS Institute of Geology & Geophysics and his co-workers challenges the conventional wisdom that the Earth's upper mantle is homogeneous. Teaming up with his colleagues from both Germany and US, Dr. Liu have conducted mineral, petrological and geochemical studies on abyssal peridotites selected from two dredge hauls in the ultraslow spreading Gakkel ridge, Arctic Ocean. Peridotite samples from one of these two dredge hauls are rarely fresh.
