Astronomically forced sphalerite growth and groundwater circulation in the Upper Mississippi Valley District, USA

Mingsong Li & Hubert Barnes
Pennsylvania State University, United States of America

Groundwater plays an essential role in global water cycles via feedback between groundwater and climate systems. However, the geologic history of groundwater activity remains unclear due to limited data. Sphalerite color banding in the Upper Mississippi Valley District (USA) is apparently caused by variation in oxidation state during sulfide precipitation which is controlled by the penetration of deeply circulating groundwater. Here, time series analysis of the...

Jan Schönig, Guido Meinhold & Keno Lünsdorf
Georg-August-University Göttingen, Geosciences Center, Germany (1); Keele University, School of Geography, Geology and the Environment, UK (2) Understanding the occurrence, extent, and lithological variability of UHP metamorphic domains is fundamental to plate tectonics and its evolution through geologic time. In the central Saxonian Erzgebirge (Germany), the highest metamorphic conditions are recorded in the “Gneiss-Eclogite Unit”, a heterogeneous nappe comprising MP to UHP rocks. Although extensively investigated, UHP rocks were only locally confirmed by the occurrence...

Dislocation creep flow laws of wet quartzite: the significance of pressure and slip systems

Lucy Lu & Dazhi Jiang
Western University, Canada (1); State Key Laboratory of Continental Dynamics, Department of Geology, Northwest University, Xi’an, China (2) An accurate flow law for dislocation creep of quartzite is critical for the understanding of continental rheology and geodynamic models. Despite many years of effort, existing creep experiments have yielded very different quartz flow law parameters. We demonstrate that the difference can be explained by considering the pressure effect on the activation enthalpy and the slip system...

A multiscale numerical modelling investigation of quartz CPO variation due to flow partitioning

Ankit Bhandari & Dazhi Jiang
University of Western Ontario, Canada

Quartz crystallographic preferred orientations (CPOs) in natural mylonites can vary to such an extent that they apparently give opposite senses of shear within a single thin section. Many qualitative explanations have been proposed. Here, we take a multiscale numerical approach to investigate the variation of quartz CPOs resulting from flow partitioning in a ductile shear zone environment. We couple our self-consistent Eshelby formalism for power-law viscous composite materials...

Christian Olaf Mueller, Jacob Waechter & Alexander Malz
Geological Survey of Saxony-Anhalt, Germany

Three-dimensional geological modelling is usually constraint by seismic and borehole data. However, in geological settings of high complexity and sparse, restricted or ambiguous available information additional geoscientific data and methods have to be considered. For this purpose, the incorporation of gravity data holds enormous potential to improve structural interpretations and allows for cross-validation and harmonization of geological models. Herein, we demonstrate an integrated approach of gravity interpretation and modelling...

Maryam Mansouri & Matthias Hinderer
Technische Universität Darmstadt, Germany

For the first time, we quantified the erosional pulse around the Permian-Triassic Boundary (PTB) over an entire sedimentary basin. Our GIS-based analysis relies on basin-wide homogenized seismic, sedimentary and stratigraphic data of the Petroleum Geological Atlas of the Southern Permian Basin. We calculated sediment volumes, sediment fluxes and sedimentation rates (SR) averaged over the entire basin from isopach maps of the Rotliegend, the Zechstein, the Lower, Middle and Upper...

Indentation and transfer of deformation between different orogenic systems: the greater Adria - Pannonian - Carpathians system

Liviu Ciprian Matenco & Douwe van Hinsbergen
Utrecht University, The Netherlands

Indentation is used to define the collisional mechanics of small plates flanked by large subduction systems creating significant thickening and lateral escape of continental units. The close spatial proximity creates a situation where deformation is actively transferred between different subduction systems during their different stages of orogenic evolution. We study this transfer by observation and modelling of indentation and orogenic evolution in the Central Mediterranean system. The evolution of the...
