Der Beitrag gibt einen Überblick über eine wirtschaftliche Verwertbarkeit von sächsischen Schmucksteinvormkommen.
Detecting initial aragonite and calcite variations in limestone–marl alternations
(
- Sedimentology
, 2021-05-28)
Limestone–marl alternations are commonly used for high‐resolution cyclostratigraphic studies and palaeoenvironmental reconstructions, but diagenetic studies indicate that not all limestone–marl alternations reflect genuine ...
Mid‐Infrared Spectroscopy of Anorthosite Samples From Near Manicouagan Crater, Canada, as Analogue for Remote Sensing of Mercury and Other Terrestrial Solar System Objects
(
- Journal of Geophysical Research: Planets
, 2021-08-03)
We investigated mid‐infrared reflectance spectra of anorthosite samples from Mt. Briand near the Manicouagan impact structure. Microprobe analyses of the plagioclase minerals reveal that they have a similar chemical ...
Recent developments in the Inorganic Crystal Structure Database: theoretical crystal structure data and related features
(
- Journal of Applied Crystallography
, 2019-09-23)
The Inorganic Crystal Structure Database (ICSD) is the world's largest database of fully evaluated and published crystal structure data, mostly obtained from experimental results. However, the purely experimental approach ...
Chemical Evolution of the Exceptional Arctic Stratospheric Winter 2019/2020 Compared to Previous Arctic and Antarctic Winters
(
- Journal of Geophysical Research: Atmospheres
, 2021-09-21)
The winter 2019/2020 showed the lowest ozone mixing ratios ever observed in the Arctic winter stratosphere. It was the coldest Arctic stratospheric winter on record and was characterized by an unusually strong and long‐lasting ...

)
Die Festschrift zum siebzigsten Geburtstage des Mineralogen Max Bauer (1844-1917), langjähriger, unermüdlicher und unparteiischer Redakteur des Neuen Jahrbuchs und des Centralblatts für Mineralogie, Geologie und Paläontologie, ...
Impact Experiment on Gneiss: The Effects of Foliation on Cratering Process
(
- Journal of Geophysical Research: Solid Earth
, 2019)
Two impact experiments were carried out on blocks of Maggia gneiss to assess the influence of mechanical target anisotropies on the cratering process. The experiments were done within the framework of Multidisciplinary ...
Origin of isolated seamounts in the Canary Basin (East Atlantic): The role of plume material in the origin of seamounts not associated with hotspot tracks
(
- Terra Nova
, 2020)
In contrast to seamount chains, small solitary seamounts/seamount groups have rarely been sampled despite their large number and therefore their origins remain enigmatic. Here we present new 40Ar/39Ar, trace element and ...
Carbon release and transformation from coastal peat deposits controlled by submarine groundwater discharge: a column experiment study
(
- Limnology and Oceanography
, 2020)
Abstract
Although the majority of coastal sediments consist of sandy material, in some areas marine ingression caused the submergence of terrestrial carbon-rich peat soils. This affects the coastal carbon balance, as peat ...
Serpentinization-driven H2 production from continental break-up to mid-ocean ridge spreading: unexpected high rates at the West Iberia margin
(2021)
Molecular hydrogen (H2) released during serpentinization of mantle rocks is one of the main fuels for chemosynthetic life. Processes of H2 production at slow-spreading mid-ocean ridges (MORs) have received much attention ...
