ArticleAccessory mineral U-Th-Pb ages and 40Ar/39Ar eruption chronology, and their bearing on rhyolitic magma evolution in the Pleistocene Coso volcanic field, CaliforniaSchmitt, Axel K.We determined Ar/Ar eruption ages of eight extrusions from the Pleistocene Coso volcanic field, a long-lived series of small volume rhyolitic domes in eastern California. Combined with ion-microprobe dating of crystal ages of zircon and allanite from . . .
ArticleThermochemical Evolution Of Young Rhyolites At Yellowstone: Evidence For A Cooling But Periodically Replenished Postcaldera Magma ReservoirRamos, Frank C.Between circa 170 ka and 75 ka, more than 600 km3 of high-silica rhyolite composing the Central Plateau Member (CPM) lavas of the Plateau Rhyolite erupted within the margins of Yellowstone caldera. The compositions of CPM ferromagnesian phenocrysts an . . .
ArticleErratum To: Zircon-Scale Insights Into The History Of A Supervolcano, Bishop Tuff, Long Valley, California, With Implications For The Ti-In-Zircon GeothermometerSchmitt, Axel K.Zircon has the outstanding capacity to record chronological, thermal, and chemical information, including the storage history of zoned silicic magma reservoirs like the one responsible for the Bishop Tuff of eastern California, USA.
