The Dgida Basin volcanic field, also known as the Dzhida Basin, is located south of the SW tip of Lake Baikal, near the border with Mongolia. One of a series of approximately E-W-trending depressions, the basin contains Quaternary lava flows and cinder cones ranging from 55 to 240 m in height. At least two stages of volcanism are present, the first of which includes lava flows overlying the 20 m terrace of the Dgida, Darkhintuy, and Khammey rivers. Lava flows in the Darkhintuy valley are overlain by gravels, which are in turn are overlain by lava flows from the Bartoy valley. Earlier Pleistocene-to-Holocene estimates of the age of the volcanism (summarized in Whitford Stark, 1987) were modified by age-dating by Rasskazov et al. (1996), who indicated that the final stage of activity took place during the early to mid-Pleistocene.
