An eastern block of the Samtskhe-Javakheti volcanic province of the Lesser Caucasus is named the volcanic plateau of Javakheti; it is bordered on the western (Samtskhe) block by an active regional fault. Over 5.2 million years, in comparison with the western block, it has submerged by about 130 m (Okrostsvaridze et al., 2016). Both blocks of this volcanic province have almost similar geological structure, although in the Quaternary, the Javakheti submerged block has been covered with thick dolerite flow, the so-called Akhalkalaki suite (Skhirtladze, 1958). As a result of field, petrologic, petrochemical, and isotopic work conducted by us, it was established that these formations are typical continental flood basalts (traps), which are genetically related to mantle plume flows (White and McKenzie, 1989) and not to melting products of the residual subduction oceanic crust as has been considered.
