Hydrogen adsorption characteristics of coal rock and its geological significance
Meitan xuebaoHydrogen, as an important clean energy source that can be used as an alternative to fossil energy, can reduce global greenhouse gas emissions. However, the large-scale hydrogen industry requires large reservoirs to store hydrogen, and the use of ...

Interpretation of zircon coronae textures from metapelitic granulites of the Ivrea–Verbano Zone, northern Italy: two-stage decomposition of Fe–Ti oxides [PDF]
Solid Earth, 2017 In this study, we report the occurrence of zircon coronae textures in metapelitic granulites of the Ivrea–Verbano Zone. Unusual zircon textures are spatially associated with Fe–Ti oxides and occur as (1) vermicular-shaped aggregates 50–200 µm long and

The iron record of asteroidal processes in carbonaceous chondrites [PDF]
, 2020 The valence of iron has been used in terrestrial studies to trace the hydrolysis of primary silicate rocks. Here, we use a similar approach to characterize the secondary processes, namely thermal metamorphism and aqueous alteration, that have affected carbonaceous chondrites.

Provenance history of a Late Triassic-Jurassic Gondwana margin forearc basin, Murihiku Terrane, North Island, New Zealand: petrographic and geochemical constraints [PDF]
, 2004 The Murihiku Terrane in the North Island was a forearc basin adjacent to a volcanic arc along the eastern margin of Gondwana during the Mesozoic. The rocks that infill the basin are mainly volcaniclastic sandstones and mudstones, often turbiditic, with ...

Alpine metamorphism of mafic rocks
Schweizerische Mineralogische Und Petrographische Mitteilungen, 1974 Metamorphosed mafic rocks in the Alps exhibit many characteristic mineral assemblages. They are used to study different phases of alpine metamorphism. The great variety of alpine metamorphosed mafic and ultramafic rocks is illustrated with a map of their distribution (plate I) and a listing showing their localities, size and thickness, metamorphic ...

Towards Automated Metamorphic Test Identification for Ocean System Models [PDF]
arXiv, 2021 Metamorphic testing seeks to verify software in the absence of test oracles. Our application domain is ocean system modeling, where test oracles rarely exist, but where symmetries of the simulated physical systems are known. The input data set is large owing to the requirements of the application domain.

Adaptive Metamorphic Testing with Contextual Bandits [PDF]
Journal of Systems and Software (JSS) Vol. 165 (2020) 110574, 2019 Metamorphic Testing is a software testing paradigm which aims at using necessary properties of a system-under-test, called metamorphic relations, to either check its expected outputs, or to generate new test cases. Metamorphic Testing has been successful to test programs for which a full oracle is not available or to test programs for which there are ...

Geology of Byobu Rock and Gobanme Rock, Prince Olav Coast, East Antarctica [PDF]
, 2006 We report here the geology of Byobu Rock and Gobanme Rock outcrops hitherto unmapped in the Prince Olav Coast, East Antarctica. Both these outcrops expose high-grade metamorphic and igneous rocks.

Late Precambrian U-Pb titanite age for peak regional metamorphism and deformation (Knoydartian orogeny) in the western Moine, Scotland [PDF]
, 2003 There has been controversy over the number and timing of orogenies in the Precambrian Moine block in the Scottish Caledonides since the earliest radiometric dating in the 1960s. This work challenges a recent hypothesis, that this sector of the Laurentian

Epitaxy and Topotaxy in the Aragonite‐Calcite Polymorphism
Crystal Research and Technology, EarlyView.At first distinguish epitaxy from topotaxy, which rule the main mechanisms of calcite‐aragonite transitions. Then, attempt to move from qualitative to quantitative descriptions of these transitions. Hence, it will deal with 2D (epitaxy) and 3D (topotaxy) conversions in the polymorphic system, in order to gain insight on their differences.
