Geology

The highest point of Motuoapa Peninsula, at its north-eastern tip is adacitevolcano that has been dated as last erupting at 34,500 ± 3,100 years ago.The other volcanic formations, some of which the dacite cone is built upon, are olderrhyolitewith two different eruption ages of 81,300 and 77,200 years ago.At the time of the rhyolite eruptions, they were initially on the lake floor of the formerLake Hukawhich was replaced byLake Taupōafter theOruanui eruptionof theTaupō Volcano25,400 years ago.Although themagmareservoir that fed these Motuoapa eruptions appears to be separate from the one(s) that produced the more recent much larger Taupō eruptions, the type of eruption commencing under water but not staying underwater is felt possible in the future from the Taupō Volcano.A perhaps unexpected characteristic is the thickness of the pyroclastic deposits produced at Motuoapa, as these indicate that such rhyolite dome building which was assumed to be mostly effusive, can haveexplosive pyroclasticstages that would be very disruptive and dangerous.
