Simplified modeling of the impact of lithospheric-scale geological processes on thermal histories and low-temperature thermochronometers

Abstract. Many geological processes influence or perturb the thermal state of the lithosphere. This presents a challenge for relating thermal history data modeled from thermochronometers such as apatite and zircon fission-track and (U-Th)/He dating to geological evolution, a prim...

Eruption source parameters for a Canadian mafic explosive eruption: an example from Sii Aks (Tseax) volcano

Abstract Observations from tephra fall deposits are needed to constrain input parameters used to model tephra fall hazard, but this is challenging for mafic Canadian volcanoes, which are often in remote locations. Here, we present eruption source parameters (ESPs) for the approxi...
