A new paleomagnetic constraint on the duration of a twin caldera-forming eruption sequence: a potential solution to an enduring problem in decoding >VEI 7 eruption timescales

Abstract New paleomagnetic results from the twin caldera-forming Mamaku–Ohakuri eruption deposits in the Taupō Volcanic Zone of New Zealand show that the entire pyroclastic sequence accumulated within a geomagnetic excursion event. The deposits are predominately unconsolidated and include multiple a...
