Crustal‐Scale Sheath Folding at HP Conditions in an Exhumed Alpine Subduction Zone (Tauern Window, Eastern Alps)
; ; ; Pestal, Gerhard; Pleuger, Jan (Tectonics, 2020-02-21)
We investigate a well‐preserved paleo subduction channel that preserves a coherent part of the European continental margin exposed in the central Tauern Window (Eastern Alps), with the aim of testing models of sheath fold ... -
Cryosphere hazards in Ladakh: the 2014 Gya glacial lake outburst flood and its implications for risk assessment
; ; ; (Natural Hazards, 2020-09-05)
This article attempts to reconstruct the causes and consequences of the 2014 glacial lake outburst flood (GLOF) event in Gya, Ladakh. We analyse the evolution of the Gya glacial lake using a high temporal and high spatial ... -

Garnet of eclogite (formerly termed garnet clinopyroxenite) hosted in lenses of orogenic garnet peridotite from the Granulitgebirge, NW Bohemian Massif, contains unique inclusions of granitic melt, now either glassy or ... -
Cryptogamic organisms are a substantial source and sink for volatile organic compounds in the Amazon region
; ; ; ; ; ; ; ; ; ; ; ; ; ; ; (Communications Earth & Environment, 2021-12-21)
Cryptogamic organisms such as bryophytes and lichens cover most surfaces within tropical forests, yet their impact on the emission of biogenic volatile organic compounds is unknown. These compounds can strongly influence ... -
Crystal diffraction prediction and partiality estimation using Gaussian basis functions
(Acta Crystallographica Section A, 2023-02-17)The recent diversification of macromolecular crystallographic experiments including the use of pink beams, convergent electron diffraction and serial snapshot crystallography has shown the limitations of using the Laue ... -
Crystal distribution patterns and their anisotropy behaviour in igneous rocks: towards an automated quantification, first results
Peternell, Mark; (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)
Since approximately two decades fractal geometry offers tools for the quantification of rock fabrics, and new methods are currently under development to investigate the inhomogeneity of crystal distributions, grain- ... -
Crystal structure and characterization of magnesium carbonate chloride heptahydrate
(Acta Crystallographica Section C, 2020)MgCO3·MgCl2·7H2O is the only known neutral magnesium carbonate containing chloride ions at ambient conditions. According to the literature, only small and twinned crystals of this double salt could be synthesised in a ... -
Crystal structure of a calcium(II)–pyrroloquinoline quinone (PQQ) complex outside a protein environment
(Acta Crystallographica Section C, 2020-11-05)Pyrroloquinoline quinone (PQQ) is an important cofactor of calcium‐ and lanthanide‐dependent alcohol dehydrogenases, and has been known for over 30 years. Crystal structures of Ca–MDH enzymes (MDH is methanol dehydrogenase) ... -
Crystal structure of human CRM1, covalently modified by 2‐mercaptoethanol on Cys528, in complex with RanGTP
(Acta Crystallographica Section F, 2021-03-08)CRM1 is a nuclear export receptor that has been intensively targeted over the last decade for the development of antitumor and antiviral drugs. Structural analysis of several inhibitor compounds bound to CRM1 revealed that ... -
Crystallization of metastable monoclinic carnallite, KCl·MgCl2·6H2O: missing structural link in the carnallite family
(Acta Crystallographica Section C, 2020)During evaporation of natural and synthetic K–Mg–Cl brines, the formation of almost square plate-like crystals of potassium carnallite (potassium chloride magnesium dichloride hexahydrate) was observed. A single-crystal ... -
Crystallographic analysis of the lattice metric (CALM) from single electron backscatter diffraction or transmission Kikuchi diffraction patterns
(Journal of Applied Crystallography, 2021-05-28)A new software is presented for the determination of crystal lattice parameters from the positions and widths of Kikuchi bands in a diffraction pattern. Starting with a single wide‐angle Kikuchi pattern of arbitrary ... -
Cultural heritage and earthquakes: bridging the gap between geophysics, archaeoseismology and engineering
(Journal of Seismology, 2020-06-18)This is the editoral of a special issue that is focused on the multidisciplinary approach to cultural heritage preservation, with special care to the impact of earthquakes and their associated effects. For that, we have ... -
Curie Temperatures and Emplacement Conditions of Pyroclastic Deposits From Popocatépetl Volcano, Mexico
; ; (Geochemistry, Geophysics, Geosystems, 2022-08-29)
Most pyroclastic deposits of Popocatépetl volcano were emplaced at high temperatures and have similar mafic to more evolved compositions, suggesting a long‐lived, interconnected magma environment. We performed a magnetic ... -
Current and future state of groundwater salinization of the northern Elbe-Weser region
; ; ; ; (Grundwasser, 2021-11-11)
Salinization of the upper aquifer of the northern Elbe-Weser region almost extends to the surface. Chloride content exceeds 250 mg/l and the groundwater is therefore, according to the German Drinking Water Ordinance, not ... -
Current extinction rate in European freshwater gastropods greatly exceeds that of the late Cretaceous mass extinction
; ; ; ; ; ; ; (Communications Earth & Environment, 2021-05-21)
The Cretaceous–Paleogene mass extinction event 66 million years ago eradicated three quarters of marine and terrestrial species globally. However, previous studies based on vertebrates suggest that freshwater biota were ... -
