Rapid Magma Generation or Shared Magmatic Reservoir? Petrology and Geochronology of the Rat Creek and Nelson Mountain Tuffs, CO, USA

open access: yesFrontiers in Earth Science, 2019
Large-volume silicic volcanism poses global hazards in the form of proximal pyroclastic density currents, distal ash fall and short-term climate perturbations, which altogether warrant the study of how silicic magma bodies evolve and assemble.

Biomineralization of primary carbonate cements: a new biosignature in the fossil record from the Anisian of Southern Italy

open access: yesLethaia, EarlyView., 2021
Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

Investigation of the effect of soil mineral composition on soil organic matter stability

open access: yesSoil and Water Research, 2016
The soil organic matter (SOM) pools with different stability play different roles in the agricultural and environmental processes, e.g. in the global carbon cycle.

Tephrostratigraphy and Magma Evolution Based on Combined Zircon Trace Element and U-Pb Age Data: Fingerprinting Miocene Silicic Pyroclastic Rocks in the Pannonian Basin

open access: yesFrontiers in Earth Science, 2021
We present a novel approach to use zircon as a correlation tool as well as a monitor for magma reservoir processes in silicic volcanic systems. Fingerprinting eruption products based on trace element content and U-Pb dates of zircon offers a promising ...

Continental weathering as the source of iron in Jurassic iron oolites from Switzerland

open access: yesSwiss Journal of Geosciences, 2023
Iron is extremely insoluble in oxic seawater. The lack of a large aqueous reservoir means that sediments rich in authigenic iron are rare in the modern ocean.

Mineralogical and Geochemical Constraints of the REE Accumulation in the Almásfüzitő Red Mud Depository in Northwest Hungary

open access: yesApplied Sciences, 2019
Detailed mineralogical and geochemical study of red mud samples from Hungary suggests geological and geochemical processes that determine the spatial distribution of certain elements inside the red mud pitfalls. The major processes are the following: (1)

Pinite-cordierite from spotted slate of the Brajkovac contact metamorphic aureole (Dudovica locality, central Serbia) [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva, 2013
The Paleozoic very low to low-grade metamorphic rocks of the Bukulja-Lazarevac Unit designated as Drina, Golija and Birač formations are contact metamorphosed by the intrusion of the Tertiary Brajkovac granodiorite into spotted slates and ...

Modeling microfracture geometry to the asses the function of a karst system (Vízfő spring catchment area, Western Mecsek Mountains, Hungary)

open access: yesGeologia Croatica, 2015
One of the current objectives of karst research is to understand the spatial dynamics of karstic processes that increase ordecrease pore volume. Although we can construct 3D numerical models, it is a complex, multi-step process. These modellingapproaches
