One of the well-known areas with youngest volcanism in the Lesser Caucasus is located in the vicinity of the Borzhomi City (central Georgia) famous by mineral water springs. This relatively small area hosts four volcanoes (Tsitelidabadzveli, Tsikhisdzhvari, Mukhera, and Sargavi), which yielded extended (from 2 to 13 km long) flows of andesite to, subordinate, basaltic andes-ite lavas (figure).In scientific works dedicated to different aspects of Neogene-Quaternary magmatism of the Caucasus region, manifestations of basaltic andesite-andesite volcanism in the examined part of the Lesser Caucasus mountainous system are usually united into the Bakuri-ani-Borzhomi neovolcanic area 1 and others. It is composed of Upper Cretaceous carbonate bands, Pale-ocene-Lower Eocene terrigenous rocks of the Borzhomi series, and Middle Eocene-Oligocene volcano-sedimentary sequences.
