Dyke emplacement in Tenerife (Canary Islands): Field studies and numerical models
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)Dykes are magma-driven extension fractures and the main conduits for magma in volcanic eruptions. To understand the mechanics of dyke emplacement is thus essential to assess volcanic hazards. To improve the understanding of ... -
Dynamic Compressive Strength and Fragmentation in Felsic Crystalline Rocks
; ; Padmanabha, Vivek; Poelchau, Michael H.; Schäfer, Frank (Journal of Geophysical Research: Planets, 2020)
Brittle deformation in rocks depends upon loading rate; with increasing rates, typically greater than ~102 s−1, rocks become significantly stronger and undergo increasingly severe fragmentation. Dynamic conditions required ... -
Dynamic expression of ancient and novel molluscan shell genes during ecological transitions - Research article
Jackson, Daniel J.;; Degnan, Bernard M. (BMC evolutionary biology, 2007)
Background: The Mollusca constitute one of the most morphologically and ecologically diverse metazoan phyla, occupying a wide range of marine, terrestrial and freshwater habitats. The evolutionary success of the molluscs ... -
Dynamic Two‐Phase Flow Modeling of Melt Segregation in Continental Crust: Batholith Emplacement Versus Crustal Convection, With Implications for Magmatism in Thickened Plateaus
; ; ; (Geochemistry, Geophysics, Geosystems, 2023-05-10)
Abstract Magmatic processes in the continental crust such as crustal convection, melt ascent, ...

Dynamical X-ray diffraction imaging of voids in dislocation-free high-purity germanium single crystals
(Journal of Applied Crystallography, 2020)White-beam X-ray topography has been performed to provide direct evidence of micro-voids in dislocation-free high-purity germanium single crystals. The voids are visible because of a dynamical diffraction contrast. It is ... -
Dynamics of Greenhouse Gases (CH4 and CO2) in Meromictic Lake Burgsee, Germany
;; (Journal of Geophysical Research: Biogeosciences, 2022-08-19)
Extraordinary amounts of greenhouse gases can be stored within the monimolimnion of meromictic lakes, that is, in the water body which is excluded from mixing events. Lake Burgsee (Thuringia, Germany) is a shallow (depth ... -
Dynamics of soil organic carbon in the steppes of Russia and Kazakhstan under past and future climate and land use
; ;; ; ; ; ; (Regional Environmental Change, 2021-07-10)
Changes in land use and climate are the main drivers of change in soil organic matter contents. We investigated the impact of the largest policy-induced land conversion to arable land, the Virgin Lands Campaign (VLC), from ... -
Dynamik des Stickstoffhaushaltes einer Sand-Braunerde nach vierjähriger Brache in Abhängigkeit von der landwirtschaftlichen Nutzungsintensität
(Univ. Dresden, 2005)Um für ertragsschwache, sandige Böden des mitteldeutschen Agrarraumes Aussagen bzw. Empfehlungen hinsichtlich einer ökologisch vertretbaren Wiederinbetriebnahme brachgefallener Flächen treffen zu können, wurden auf einem ... -

Dynamik fluvialer Verlagerungsprozesse - Beobachtungen an der Mulde zwischen Eilenburg und Bad Düben
(SelbstverlagGöttingen, 2021)Natürliche Prozesse der Flussbettverlagerung wie Gerinnemigration oder Gerinneausbrüche sind in deutschen Flüssen aufgrund des hohen Ausbaugrades eine Seltenheit. Eine der wenigen Ausnahmen, an denen diese fluvialtypischen ... -
Dynamische Sedimentationsvorgänge, Diagenese und Biofazies unterkretazischer Plattformränder (Apt-Alb; Soba-region, Prov. Cantabria, N-Spanien)
(Selbstverlag Fachbereich Geowissenschaften, FU Berlin, 1995)Am Westrand des Basko-Kantabrischen Beckens (Soba-Region, Prov. Cantabria, Nordspanien) sind die Plattform/Becken-Übergangszonen des Apt und Alb in nahezu ungestörtem Verband erhalten. Entlang dieser Randzonen befinden ... -

Early Eocene magnetostratigraphy and tectonic evolution of the Xining Basin, NE Tibet
; ; ; ; ; ; ; ; (Basin Research, 2022-10-12)
The Cenozoic strata of the Xining Basin, NE Tibet, have provided crucial records for understanding the tectonic and palaeo‐environmental evolution of the region. Yet, the age of the lower part of the sedimentary stratigraphy ... -
Early Famennian bryozoan fauna from the Baqer-abad section, northeast Isfahan, central Iran
; ; (Palaeobiodiversity and Palaeoenvironments, 2020-04-03)
A bryozoan fauna from the Upper Devonian (lower Famennian) of the Bahram Formation of the Baqer-abad section in central Iran contains four species: three trepostomes and one rhabdomesine cryptostome. Two trepostome species ... -
Early Holocene aeolian sediments in southwestern Crete−preliminary results
; ; ; ; (Mediterranean Geoscience Reviews, 2021-07-27)
The soilscapes along the southern and western coast of Crete (Greece) are dominated by coarse-grained reddish-brown slope sediments whose natural (pre-anthropogenic) configuration and properties are difficult to reconstruct ... -

Early paleozoic diversification of sponges ; new data and evidences
; Mehl, Dorte (Geologisch-paläontologische Mitteilungen, Innsbruck, 1995)
Sponges are primitive metazoan organisms which occur since the late Proterozoic. The oldest sponge remains (hexactinellids) are from a shallow marine carbonate facies of the late Sinian Shibantan Member (China). From the ...
