The low Sukadana Plateau, 30 x 11 km wide, is a volcanic expression of the Sukadana Basalts of Pleistocene age (Barber et al., 2005). The plateau itself covers an area of approximately 1000 km2 and contains fissure-fed lava flows 2-3 m thick issued from NW-SE trending fissures (Barber et al., 2005; van Bemmelen 1949b). The basaltic region may be over 200 m thick in areas, localized around eruptive centers, but no deposits greater than 10 m have been observed. Some columnar jointing is present. K-Ar dating gave ages ranging from 0.44 Ma to 1.15 Ma for the oldest samples (Soeria-Atmadja et al., 1985 in Barber et al., 2005), but more recent ages measured from more well-preserved flows and spatter cones are around 0.01 to 0.8 million years. Sukadana is technically part of the back-arc region of the Sumatra Volcanic Arc Segment, evidenced by notable textural and compositional differences from the arc volcanics, as well as a similarity to the back-arc Bukit Telor basalts (Barber et al., 2005).
