Petrology of alkali basalts of Zlot, Timok Magmatic Complex (Eastern Serbia)

Various disequilibrium features in alkali basalt of Zlot reflect complex convection effects and recharge, most probably in a shallow magma chamber. Major and trace elements data indicate that alkali basalts of Zlot originated from magmas deriving from metasomatized mantle wedge above a subducting and dehydrating plate. However the investigated rocks did not originate from primary magmas, but from a magma which has undergone considerable fractional crystallization.
