To the Editor — Detailed analysis of volcanic materials1 allows the study of eruptions that have not been witnessed directly. Rotella et al.2 undertake the challenge of interpreting submarine volcaniclastic deposits around Macauley Volcano, part of the Kermadec Arc in the southwest Pacific Ocean. They propose a ‘Tangaroan’ eruption style, based on the textural characteristics of dredged pumice ...

Thallium (Tl) isotope ratios are an emerging tool that can be used to trace crustal recycling processes in arc lavas and ocean island basalts (OIBs). is a highly volatile metal enriched volcanic fumaroles, but it unknown whether degassing of Tl from subaerial has significant effect on their residual compositions. Here, we present concentration data experiments best explained by Rayleigh kinetic...

Purpose. To identify features of methane-air mixture flow within the steel degassing pipelines as well those ones made composite materials, to develop engineering solutions improving their reliability for actual use. Methodology. solve problem increasing capacity mine pipelines, an analysis fundamental studies on physical and mechanical properties methane processes its recovery in a environment...
