151. Destruction of North China Craton challenges classical theory about cratons stability
    Cratons are stable tectonic parts of the continental lithosphere, which account for about 50% of the continental surface formed during the Precambrian. Cratons have thick lithosphiric roots, cold geotherm and low density, which maks the floating of cratons above the convective asthenosphere and...

152. Both tholeiitic and alkalic melt inclusions were found in a single hand specimen of mafic rocks
    To date, a large number of studies on the origin of mafic volcanic rocks are based on the geochemical data of whole rocks. However, whole rocks record only a ‘mixture’ of compositions produced by complex petrogenesis involving partial melting in the mantle, magma mixing in magma chamber(s), a...
