Abstract Samples and documentation of outcrops drillings, facies analysis, whole rock geochemistry radiometric ages have been employed to re-evaluate the Late Carboniferous Tharandt Forest caldera (TFC) co-genetic Niederbobritzsch granite (NBG) in eastern Erzgebirge near Dresden, Germany. The c. 52 km 2 TFC harbours strongly welded ignimbrites with a preserved minimum thickness 550 m. Compositi...

Catastrophic eruptions of rhyolitic super volcanoes require large volumes silicic magma to be extracted from a crystal-rich mush at high rates. However, fast melt extraction is thought difficult because the low permeability mushes and viscosities melts. Here, we show that induced ephemeral pathways in may critical. During uniaxial compression mush, driven by impingement recharging magmas below,...

The Gacun deposit is a typical Volcanic Hosted Massive Sulfide (VHMS) associated with Late Triassic seafloor calc-alkaline felsic volcanics. Studies of zircon ages, petrology, major and trace element geochemistry, Sr-Nd-Hf isotope geochemistry volcanic rocks from the Northern Yidun arc were undertaken in this paper. We reshaped magmatic system activity time, defined origin magma evolution, prop...

Terrestrial and extraterrestrial rocks exhibit significant variations in their mass-dependent Ti isotopic compositions, with basalts being isotopically lighter than evolved lithologies. The observed trend from light to heavy compositions more primitive differentiated agrees theoretical predictions that isotopes are sequestered Fe–Ti oxides. However, there lingering questions about the exact ext...

Due to a lack of visible tephras in the Dead Sea record, this unique palaeoenvironmental archive is largely unconnected well-established Mediterranean tephrostratigraphy. Here we present first results ongoing search for cryptotephras International Continental Drilling Program (ICDP) sediment core from deep basin. This study focusses on Lateglacial (~15–11.4 cal. ka BP), when Lake Lisan – precur...

Abstract Bromine is a key halogen element in the quantification of volcanic volatiles, but analytical difficulties measuring its very low abundances have prevented progress understanding behavior and role emissions. We present new data set bromine, chlorine, fluorine concentrations melt inclusions matrix glasses for two rhyolitic super-eruptions from Toledo Valles calderas, New Mexico, USA. sho...
