Neogene basanite lavas of Kozákov volcano, located along the Lusatian fault in the north-eastern Czech Republic, contain abundant anhydrous spinel lherzolite xenoliths, which provide an exceptionally continuous sampling of the upper two-thirds of central European lithospheric mantle. Spinel lherzolite yields a range of two-pyroxene temperatures from 680 ºC to 1070 ºC, and the xenoliths are estimated to originate from depths of 32 to 70 km, based on a tectonothermal model for basaltic underplating associated with Neogene rifting. The sub-Kozákov mantle is layered, consisting of an equigranular upper layer (32 to 43 km), a protogranular intermediate layer that contains spinel-pyroxene symplectite after garnet (43 to 67 km), and an equigranular lower layer (67 to 70 km).
