摘要:Abstract(#br)Lake City Caldera (22.93 ± 0.02 Ma) is the youngest of 25 Tertiary calderas within the Southern Rocky Mountain Volcanic Field (SRMVF) and offers an opportunity to study the relationship between plutonic rocks and their volcanic equivalents. Extreme topographical...

摘要:Abstract(#br)U-Pb detrital zircon age and trace element data from a Devonian sandstone sample of the Beacon Supergroup provide new evidence for 1450 Ma zircon sources in Antarctica. These grains yield a dominant 1450 Ma (Mesoproterozoic, Calymmian) age probability peak with U/Th ...

摘要:Abstract(#br)Studying the inventory and distribution of lithium (Li) in rhyolitic magmas, and the potential Li isotope fractionation during progressive crystallisation is crucial to understand the formation of economic Li deposits. Lithium concentrations and isotopic composi...

摘要:Abstract(#br)Arc volcanoes generally emit water-rich, high-viscosity silicic magmas, which are prone to erupt explosively. However, effusive behavior is a common occurrence despite the high-H 2 O, high viscosity conditions. The contrasting shift from effusive to explosive be...

摘要:Abstract(#br)The partitioning of REE, Y and Sc (R 3+ ) between olivine and melt has been investigated experimentally during basalt-carbonate interaction. Three synthetic basalts ( melt Mg# 72 , melt Mg# 75 and melt Mg# 78 ) were doped with 0, 10 and 20 wt% CaCO 3 and then eq...

摘要:Abstract(#br)The geochemical evolution of olivine from primitive magmatic skarn environments has been studied by atmospheric pressure experiments carried out at 1250, 1200, and 1150 °C under QFM oxygen buffering conditions. The starting materials were three synthetic basalts...

摘要:Abstract(#br)The diffuse emission of CO 2 from the south east sector of Nisyros caldera (Lakki plain) has been measured during a detailed survey (~1400 soil CO 2 flux measurements) performed in October 2018. The gas emissions are fed by hydrothermal sources and, in minor par...

摘要:Abstract(#br)Constraining the contribution of crustal lithologies to silicic magmas has important implications for understanding the dynamics of these potentially highly explosive systems. Low- δ 18 O rhyolite lavas erupted after caldera-forming events in Yellowstone have be...

摘要:Abstract(#br)Radioisotopic dates for Late Pleistocene to Holocene silica-undersaturated volcanic rocks are often imprecise, limiting our ability to assess the frequency of eruptions in alkaline volcanic provinces, evaluate related volcanic risk and date associated archaeolog...

摘要:Abstract(#br)The diffusivity of S in a hydrous dacitic melt (4.5–6.0 wt.% H 2 O) has been investigated in the temperature ( T ) and pressure ( P ) range of 950 °C to 1100 °C and 200 to 250 MPa, respectively. Three series of experiments were conducted at relatively low oxygen...
