Introduction
The Tawau Hills is a large Miocene to late-Pleistocene volcanic field on the Semporna Peninsula in the NE part of the island of Borneo co. It is in the Malaysian province of Sabah, across Port Cowie bay from the the Indonesian province of Kalimantan. Tahir et al. (2010) noted that the larger mountains resulted from Pleistocene dacite eruptions on top of older andesites; late Pleistocene olivine basalt lavas originated from multiple small cones (eg. Tiger Hill, Bombalai Hill, and Quoin Hill). Two young lava flows from Bombalai extend almost to the coastal plain; they were considered younger than a lava flow radiocarbon dated at about 27,000 years before present (Kirk, 1968), but later workers make no mention of Holocene activity. The lavas from the Tawau area are geochemically distinct from those erupted from fissures at Mostyn (Macpherson et al., 2010), also on the Semporna Peninsula about 30 km NE.---
