1. The Palau Islands are located at 7°30'N and are the only emerging feature on the 2500 km long Kyushu-Palau Ridge.
2. The islands are mainly composed of uplifted carbonate reefs, with larger islands being volcanoes containing basalt to komatiite and rare boninite.
3. Volcanic activity began in the late Eocene and ended in the early Miocene, forming a low-K primitive island arc series with no oceanic ridge basalts present.
