Effect of high temperature and strain rate on the elastic modulus of rocks: a reviewInternational Journal of Earth Sciences - Tập 110 - Trang 2639-2660 - 2021
Tubing Yin, Yongjun Chen, Xibing Li, Qiang Li
Elastic modulus is an important parameter in rock mechanics and engineering geology that determines the mechanical properties of rocks. To analyze the effect of temperature and dynamic loading conditions on the elastic modulus of typical rocks, data and results from international publications are classified, analyzed, discussed and summarized. The findings show that the elastic modulus of differen...... hiện toàn bộ
The Main Ostrava Whetstone: composition, sedimentary processes, palaeogeography and geochronology of a major Mississippian volcaniclastic unit of the Upper Silesian Basin (Poland and Czech Republic)International Journal of Earth Sciences - Tập 102 - Trang 989-1006 - 2013

The Main Ostrava Whetstone (MOW) is an important lithostratigraphic horizon of the Late Carboniferous sedimentary fill of the late Palaeozoic foreland Upper Silesian Basin. It is the largest and best-identified volcanogenic horizon in the basin, reaching thicknesses of 15.3 m and occupying an area of ca 2,973 km2 and a volume after lithification of 9.24 km3. It consists of volcanic materials trans...... hiện toàn bộ

Reconstruction of the differentiated long-term exhumation history of Fuerteventura, Canary Islands, Spain, through fission-track and (U-Th–Sm)/He dataInternational Journal of Earth Sciences - Tập 99 - Trang 675-686 - 2009
Martin Wipf, Ulrich Anton Glasmacher, Daniel Fritz Stockli, Axel Emmerich, Thilo Bechstädt, Heinrich Baur
Miocene Intrusives and Lower Cretaceous siliciclastic sedimentary rocks from the Basal Complex in western-Fuerteventura were analyzed with low-temperature thermochronometric methods such as fission-track, and (U–Th–Sm)/He dating, in order to reveal the evolution of the island’s exhumation history. The obtained thermochronometric data yields a very slow rate of cooling in the order of 1.5–3°C/Myr f...... hiện toàn bộ
Permian–Triassic red-stained albitized profiles in the granitic basement of NE Spain: evidence for deep alteration related to the Triassic palaeosurfaceInternational Journal of Earth Sciences - Tập 108 - Trang 2325-2347 - 2019
Carles Fàbrega, David Parcerisa, Médard Thiry, Christine Franke, Andrey Gurenko, David Gòmez-Gras, Jesús Solé, Anna Travé
Extensive areas of the Variscan granitic basement in NE Spain display profiles of red-stained albitized facies characterized by albitization of Ca-plagioclase, chloritization of biotite and microclinization of orthoclase, along with the alteration of igneous quartz to secondary CL-dark quartz. These profiles have a geopetal structure beneath the Triassic unconformity, with a very intense and perva...... hiện toàn bộ
Dislocation microstructure and phase distribution in a lower crustal shear zone – an example from the Ivrea-Zone, ItalyInternational Journal of Earth Sciences - - 2001
Thomas Kenkmann, Georg Dresen
The analysis of fabric and microstructure across an amphibolite facies shear zone of mafic composition reveals that the strain-dependent change from grain size insensitive to grain size sensitive creep is associated with a fundamental reorganization of the mylonitic fabric. At moderate strain a banded mylonite evolves from a metagabbro, which displays a mechanically-induced compositional layering...... hiện toàn bộ
