    Hydroclimate in the Pamirs Was Driven by Changes in Precipitation‐Evaporation Seasonality Since the Last Glacial Period 
    Aichner, Bernhard; Makhmudov, Zafar; Rajabov, Ilhomjon; Zhang, Qiong; Pausata, Francesco S. R.; Werner, Martin; Heinecke, Liv; Kuessner, Marie L.; Feakins, Sarah J.; Sachse, Dirk; Mischke, Steffen (American Geophysical Union (AGU), 2019-12-03)
    The Central Asian Pamir Mountains (Pamirs) are a high-altitude region sensitive to climatic change, with only few paleoclimatic records available. To examine the glacial-interglacial hydrological changes in the region, we analyzed the geochemical ...

    Magma reservoir dynamics at Toba caldera, Indonesia, recorded by oxygen isotope zoning in quartz 
    Budd, David A.; Troll, Valentin R.; Deegan, Frances M.; Jolis, Ester M.; Smith, Victoria C.; Whitehouse, Martin J.; Harris, Chris; Freda, Carmela; Hilton, David R.; Halldorsson, Saemundur; Ilya N., Ilya N. (Springer Nature, 2017-01-25)
    Quartz is a common phase in high-silica igneous rocks and is resistant to post-eruptive alteration, thus offering a reliable record of magmatic processes in silicic magma systems. Here we employ the 75 ka Toba super-eruption as a case study to show ...

    Rapid CO2 mineralisation into calcite at the CarbFix storage site quantified using calcium isotopes 
    Pogge von Strandmann, Philip A. E.; Burton, Kevin W.; Snæbjörnsdóttir, Sandra Ósk; Sigfússon, Bergur; Aradóttir, Edda S.; Gunnarsson, Ingvi; Alfreðsson, Helgi A.; Mesfin, Kiflom G.; Oelkers, Eric H.; Gíslason, Sigurður Reynir (Springer Science and Business Media LLC, 2019-04-30)
    The engineered removal of atmospheric CO 2 is now considered a key component of mitigating climate warming below 1.5 °C. Mineral carbonation is a potential negative emissions technique that, in the case of Iceland’s CarbFix experiment, precipitates ...

    A review of statistical tools for morphometric analysis of juvenile pyroclasts 
    Dürig, Tobias; Ross, Pierre-Simon; Dellino, Pierfrancesco; White, James D. L.; Mele, Daniela; Comida, Pier Paolo (Springer Nature, 2021-10-30)
    Morphometric analyses are based on multiparametric datasets that describe quantitatively the shapes of objects. The stochastic nature of fracture-formation processes that break up magma during explosive eruptions yields mixtures of particles that have ...

    Standardized analysis of juvenile pyroclasts in comparative studies of primary magma fragmentation: 2. Choice of size fraction and method optimization for particle cross-sections 
    Comida, Pier Paolo; Ross, Pierre-Simon; Dürig, Tobias; White, James D. L.; Lefebvre, Nathalie (Springer Nature, 2021-12-27)
    The morphological and textural features of juvenile pyroclasts record crucial details on magma conditions at the time of fragmentation. Their study is therefore essential to better understand the dynamics of explosive eruptions. Unfortunately, the ...
