“…Elbrus and Mt. Kazbek regions began around 250 ka ago (Lebedev et al, 2010;Lebedev, Vashakidze, et al, 2011;Lebedev & Vashakidze, 2014). Magma is generally thought to be mantle derived, as indicated by the Sr-Nd-O isotopic systematics of recent volcanic rocks and the high helium isotopic values of associated subsurface fluids (Polyak et al, 2009(Polyak et al, , 2000Tutberidze, 2012).…”

• There is a marked lateral change in the Cenozoic cooling history of the crystalline core of the western Greater Caucasus • The region with young cooling ages (between Mt. Elbrus and Mt. Kazbek) coincides with an area of mantle-sourced Late Miocene and younger magmatism • If driven by buoyancy forces, cooling must be partitioned over short wavelengths by lithospheric heterogeneities Vincent et al.
