The Songaksan tuff ring (STR) is one of several recent hydrovolcanic centers on Jeju Island,
Korea, which provides an excellent example of proximal-to-distal facies changes in wet
pyroclastic surge deposits. A multidisciplinary study has been carried out on the STR and
adjacent lithostratigraphic units to constrain absolute age, geochemical characteristics, and
Quaternary depositional history. A number of rock units were identified inside the crater of
the STR, including Scoria deposit I, trachybasalt lava, Scoria deposit II, and a late-stage …
