Chronology and dynamics of a large silicic magmatic system: Central Taupo Volcanic Zone, New Zealand

摘要: The central Taupo Volcanic Zone in New Zealand is a region of intense Quaternary silicic volcanism accompanying rapid extension continental crust. At least 34 caldera-forming ignimbrite eruptions have produced complex sequence relatively short-lived, nested, and/or overlapping volcanic centers over 1.6 m.y. Silicic at similar to the Yellowstone system size, longevity, thermal flux, and magma output rate. However, contrasts with exceptionally high frequency, but small eruptions. This contrast reflects thin, rifted nature crust, which precludes development long-term magmatic cycles Taupo. 11 refs., 4 figs., 1 tab.
