Acigöl rhyolite field, Central Anatolia (part 1): high-resolution dating of eruption episodes and zircon growth rates
(Springer, 2011)Protracted pre-eruptive zircon residence is frequently detected in continental rhyolites and can conflict with thermal models, indicating briefer magma cooling durations if scaled to erupted volumes. Here, we present ... -
Acigöl rhyolite field, central Anatolia (part II): geochemical and isotopic (Sr–Nd–Pb, δ¹⁸O) constraints on volcanism involving two high-silica rhyolite suites
(Springer, 2011)The Acigöl rhyolite field erupted the most recent high-silica rhyolites within the Cappadocian Volcanic Province of central Anatolia, Turkey. It comprises two sequences of domes and pyroclastic rocks with eruption ages of ... -
Identifying the volcanic eruption depicted in a Neolithic Painting at Çatalhöyük, Central Anatolia, Turkey
(PUBLIC LIBRARY SCIENCE, 2014)A mural excavated at the Neolithic Çatalhöyük site (Central Anatolia, Turkey) has been interpreted as the oldest known map. Dating to ~6600 BCE, it putatively depicts an explosive summit eruption of the Hasan Dağı twin-peaks ... -
Re-anchoring the late Pleistocene tephrochronology of New Zealand based on concordant radiocarbon ages and combined ²³⁸U/ ²³ºTh disequilibrium and (U-Th)/He zircon ages
(Elsevier, 2012)The caldera-forming Rotoiti eruption from Okataina volcano was one of the largest rhyolite events of the last 100ka in the Taupo Volcanic Zone, New Zealand. Its associated widespread tephra layer (Rotoehu tephra) is a ... -
Sub-millennial eruptive recurrence in the silicic Mangaone Subgroup tephra sequence, New Zealand, from Bayesian modelling of zircon double-dating and radiocarbon ages
(Elsevier, 2020)Accurate dating of young (<1 Ma) volcanic eruptions has long been a challenge for modern geochronology given the scarcity of datable mineral phases and low quantities of radiogenic daughter products. Combined U-Th-Pb and ...
