| Mount Bombalai is part of a large Pliocene to Pleistocene or younger volcanic field on the Semporna Peninsula in the NE part of the island of Borneo. The volcano is part of the Malaysian province of Sabah, across Cowie Harbor from the the Indonesian province of Kalimantan. The low volcanic cone is located north of Sebatik Island and has a roughly 300-m-wide crater breached to the south. Two young lava flows extend almost to the coastal plain. The flows were considered younger than a lava flow radiocarbon dated at about 27,000 years before present, and the extrusion of basaltic lavas possibly continued into Recent (Holocene) time (Kirk, 1968). This marks the only known area of possible Holocene volcanism on Borneo. Other areas of late Quaternary dacitic and basaltic volcanism occur along the Semporna Peninsula. | |||
