Coupled Evaluation of DFN Models and Well Hydraulics for Improved Estimation of Hydraulic Fracture Apertures

Tivadar M. Tóth

To characterise the fracture network geometry of a fluid reservoir, fundamental parameters are used in a DFN simulation algorithm. However, evaluating the hydrodynamic behaviour of such rock bodies also requires apertures of individual fractures. Aperture is usually not treated as an independent …

Overview of the pre-Neogene basement collage of the Pannonian Basin

Gábor Tari, László Csontos, Balázs Koroknai, Csaba Krézsek et autres

The extensional Neogene Pannonian Superbasin was superimposed on an Alpine, Cretaceous-Paleogene compressional realm which left a significant structural footprint in the pre-rift basement. Even though the surrounding Eastern Alps, Carpathians, and Dinarides project below the Pannonian Basin, even the existence of Alpine …

Zirconolite-bearing symplectites in micro-ijolites: implications for subsolidus processes during ongoing magmatism at Oldoinyo Lengai, Tanzania

Noémi Halász, Péter Pekker, Mihály Pósfai, Tibor Guzmics et autres

Olivine-phlogopite micro-ijolite enclaves from Oldoinyo Lengai record complex, multistage magmatic processes. These rocks preserve evidence of subsolidus reactions demonstrated by the development of symplectites. The symplectites studied here are present in lamellae and display bimodal grainsize distributions of their constituent phases: diopside …

Geochemistry of CO2-rich gas emissions in the Carpathians: Multiscale geological sources and implications for orogenic degassing

Boglárka Mercedesz Kis, Réka Szalay, Antonio Caracausi, Paolo Randazzo et autres

Degassing of deep-seated fluids is a key process occurring in orogenic systems, yet its sources and controlling mechanisms remain poorly constrained. The Carpathians represent a major degassing province in Europe, where CO 2 emissions are concentrated in the Neogene–Quaternary volcanic arc and …

Monocyte-to-lymphocyte ratio and further inflammatory parameters as potential biomarkers of suicide risk in bipolar affective disorder

B Pethö, Tamás Tényi, Diána Simon, Tivadar M. Tóth et autres

Introduction Suicide is an unresolved issue in psychiatry to this day. Suicide risk (SR) is highest for psychiatric patients with bipolar affective disorder (BD). Recent studies suggest an immunological dysregulation in the background of suicidality, and in accord with former results, our …
