Measurement of calcite crystallographic-preferred orientations by magnetic anisotropy and comparison to diffraction methods
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)The anisotropy of magnetic susceptibility (AMS) of rocks reflects the preferred orientations of minerals. Therefore AMS is a quick and easy way to characterize rock fabrics (Hrouda 1982,Borradaile 1988); the obtained result ... -
Measurement of crystallographic orientation of quartz crystal using Raman spectroscopy: application to entrapped inclusions
(Contributions to Mineralogy and Petrology, 2021-10-15)Raman spectroscopy has been widely used in mineralogy and petrology for identifying mineral phases. Some recent applications of Raman spectroscopy involve measuring the residual pressure of mineral inclusions, such as ... -

Measurements meet human observations: integrating distinctive ways of knowing in the Pamir Mountains of Tajikistan to assess local climate change
(Climatic Change, 2021-03-02)In mountain environments dimensions of climate change are unclear because of limited availability of meteorological stations. However, there is a necessity to assess the scope of local climate change, as the livelihood and ... -
Measuring vertical soil water content profiles by combining horizontal borehole and dispersive surface ground penetrating radar data
(Near Surface Geophysics, 2020)To investigate transient dynamics of soil water redistribution during infiltration, we conducted horizontal borehole and surface ground penetrating radar measurements during a 4-day infiltration experiment at the rhizontron ... -
Measuring zero water level in stream reaches: A comparison of an image‐based versus a conventional method
(Hydrological Processes, 2022-08-23)A limited number of gauging stations, especially for nested catchments, hampers a process understanding of the interaction between streamflow, groundwater and water usage during drought. Non‐commercial measurement devices ... -
Mechanical behavior of synthetic omphacite aggregates at high temperature and high pressure
(Univ. Bochum, 2009)Triaxial compression experiments were performed on the synthesized samples and Fe-bearing clinopyroxenite in a solid medium apparatus at a confining pressure of 0.75 to 2.5 GPa, temperatures 900 to 1175oC, and strain rates ... -
Mechanical Modeling of Pre‐Eruptive Magma Propagation Scenarios at Calderas
(Journal of Geophysical Research: Solid Earth, 2023-02-24)Simulating magma propagation pathways requires both a well‐calibrated model for the stress state of the volcano and models for dike advance within such a stress field. Here, we establish a framework for calculating ... -
Mechanism for Deep Crustal Seismicity: Insight From Modeling of Deformation Processes at the Main Ethiopian Rift
(Geochemistry, Geophysics, Geosystems, 2020)We combine numerical modeling of lithospheric extension with analysis of seismic moment release and earthquake b-value in order to elucidate the mechanism for deep crustal seismicity and seismic swarms in the Main Ethiopian ... -
Mechanism of uranium fixation by zero valent iron: the importance of co-precipitation
(Uranium in the aquatic environment, 2002)The coprecipitation of U (VI) with iron corrosion products from aqueous solutions by zero valent iron was investigated. The evidence of coprecipitation was demonstrated by conducting experiments with well characterized ... -
Mechanism of uranium removal from the aqueous solution by elemental iron
(Journal of hazardous materials, 2006)The effectiveness of elemental iron (Fe0) to remove uranium (U) from the aqueous phase has been demonstrated. While the mitigation effect is sure, discrepancies in the removal mechanism have been reported. The objective ... -

Mediate relation between electrical and thermal conductivity of soil
(Geomechanics and Geophysics for Geo-Energy and Geo-Resources, 2020-08-03)Thermal conductivity is a key parameter for many soil applications, especially for dimensioning shallow and very shallow geothermal systems based on the possible heat extraction rate and for modelling heat transfer processes ... -
Mediterranean wetland conservation in the context of climate and land cover change
(Regional Environmental Change, 2020-06-02)Wetlands are known to support diverse and unique species assemblages. Globally, but particularly in the Mediterranean basin, they are threatened by climate change and natural habitat loss. Despite an alarming decline of ... -
