Optimized reconstruction of the crystallographic orientation density function based on a reduced set of orientations
(
- Journal of Applied Crystallography
, 2020)
Crystallographic textures, as they develop for example during cold forming, can have a significant influence on the mechanical properties of metals, such as plastic anisotropy. Textures are typically characterized by a ...
What Can We Learn From X-Ray Fluorescence Core Scanning Data? A Paleomonsoon Case Study
(
- Geochemistry, Geophysics, Geosystems
, 2020)
X-ray fluorescence (XRF) core scanning of marine and lake sediments has been extensively used to study changes in past environmental and climatic processes over a range of timescales. The interpretation of XRF-derived ...
Strong Sequestration of Hydrogen Into the Earth's Core During Planetary Differentiation
(
- Geophysical Research Letters
, 2020)
We explore the partitioning behavior of hydrogen between coexisting metal and silicate melts at conditions of the magma ocean and the current core–mantle boundary with the help of density functional theory molecular dynamics. ...
Middle to Late Pleistocene environments based on stable organic carbon and nitrogen isotopes of loess-palaeosol sequences from the Carpathian Basin
(
- Boreas
, 2020)
Stable organic carbon and nitrogen isotopes can be used to interpret past vegetation patterns and ecosystem qualities. Here we present these proxies for two loess-palaeosol sequences from the southern Carpathian Basin to ...
Quantifying Nitrous Oxide Emissions in the U.S. Midwest: A Top‐Down Study Using High Resolution Airborne In‐Situ Observations
(
- Geophysical Research Letters
, 2021-03-06)
The densely farmed U.S. Midwest is a prominent source of nitrous oxide (N2O) but top‐down and bottom‐up N2O emission estimates differ significantly. We quantify Midwest N2O emissions by combining observations from the ...
How Important is Denitrification in Riparian Zones? Combining End-Member Mixing and Isotope Modeling to Quantify Nitrate Removal from Riparian Groundwater
(
- Water Resources Research
, 2020)
Riparian zones are important buffer zones for streams as they are hotspots of nitrate transformation and removal in agricultural catchments. However, mixing of water from different sources and various transformation processes ...
Hf-W chronology of a macrochondrule from the L5/6 chondrite Northwest Africa 8192
(
- Meteoritics & Planetary Science
, 2020)
A large, igneous-textured, and 2 cm-sized spherical object from the L5/6 chondrite NWA 8192 was investigated for its chemical composition, petrography, O isotopic composition, and Hf-W chronology. The petrography and ...
Enhanced Late Miocene Chemical Weathering and Altered Precipitation Patterns in the Watersheds of the Bay of Bengal Recorded by Detrital Clay Radiogenic Isotopes
(
- Paleoceanography and Paleoclimatology
, 2021-09-06)
The late Miocene was a period of declining CO2 levels and extensive environmental changes, which likely had a large impact on monsoon strength as well as on the weathering and erosion intensity in the South Asian Monsoon ...
Die Bedeutung der Stoff-Konstanten natürlicher Gesteine für Bauwesen, Geologie und Bergbau
(
- Fortschritte der Mineralogie, Kristallographie und Petrographie
, 1940)
Unter Heranziehen eigener Forschungsergebnisse und zahlreicher Einzelarbeiten aus den Gebieten Bauwesen, Geologie und Bergbau, wird auseinandergesetzt, wie sich aus der einfachen Werkstoffprüfung an Naturstein eine ...
Festband Reinhard Brauns
(
- Neues Jahrbuch für Mineralogie, Geologie und Paläontologie - Beilagebände; Band 64
)
Der Festband zum siebzigsten Geburtstag des Mineralogen Reinhard Brauns (1861-1937) enthält 44 Beiträge zur Kristallographie, Mineralogie, Petrographie, Geochemie und Lagerstättenkunde von seinen Freunden und Schülern ...
