Model of mantle-crust interaction and magma generation in the suprasubduction orogen (Paleozoic of the Urals)

open access: yesЛитосфера, 2018
A model of magma formation in the crust of the Urals mobile belt, which is the best example of epioceanic suprasubduction orogen, has been developed. Magma formation occurs both in the relic oceanic and in the newly formed orogen crust. In the first case

Camp Creek Revisited, One More Time: Evaluating Multiple Approaches to Quantify Peak Flow Response to Forestry for a Medium‐Size Snow‐Dominated Catchment

open access: yesWater Resources Research, Volume 62, Issue 9, September 2026.
Abstract Forest disturbance effects on peak flows have been debated for decades. Paired‐catchment analysis (PCA) has been criticized in relation to the long‐term stability of pre‐harvest regressions and the inability of chronological pairing to characterize changes in event frequency.

Resolving Micrometre‐Scale Zircon Growth in Silicic Systems by 7 μm LA‐MC‐ICP‐MS U‐Pb Dating: Linking Petrology and Geochronology in Silicic Volcanic and Granitic Rocks from Victoria, Australia

open access: yesGeostandards and Geoanalytical Research, Volume 50, Issue 3, Page 625-647, September 2026.
Key Points 7 μm spot‐diameter LA‐MC‐ICP‐MS analyses yield accurate zircon U‐Pb ages. 1013 Ω amplifier resistors improve low‐signal Pb measurements. Saturn correction protocols minimise down‐hole fractionation effects. We present a systematic evaluation of high spatial‐resolution zircon U‐Pb dating using a Thermo Scientific Neoma multi‐collector ICP‐MS ...
