Variations in the P‐T‐t of Deformation in a Crustal‐Scale Shear Zone in Metagranite
Geochemistry, Geophysics, Geosystems, 2020 Deformation in crustal‐scale shear zones occurs over a range of pressure‐temperature‐time (P‐T‐t) conditions, both because they may be vertically extensive structures that simultaneously affect material from the lower crust to the surface, and because ...

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.

Energy Science &Engineering, EarlyView.Experimental evaluation of water phase trap damage in tight sandstone reservoirs ABSTRACT The C‐S reservoir in the YQ district of Ordos basin, China, is located at a relatively shallow depth (240–720 m), with an original pressure coefficient of approximately 0.85 for the oil layer. Calculations indicate that the initial pressure of the oil layer ranges

Spectral Evidence for Amorphous Silicates in Least-processed CO Meteorites and Their Parent Bodies [PDF]
, 2018 Least-processed carbonaceous chondrites (carbonaceous chondrites that have experienced minimal aqueous alteration and thermal metamorphism) are characterized by their predominately amorphous iron-rich silicate interchondrule matrices and chondrule rims.

Automated identification of metamorphic test scenarios for an ocean-modeling application [PDF]
, 2020 Metamorphic testing seeks to validate software in the absence of test oracles. Our application domain is ocean modeling, where test oracles often do not exist, but where symmetries of the simulated physical systems are known. In this short paper we present work in progress for automated generation of metamorphic test scenarios using machine learning ...

Evolving Subduction Zone Thermal Structure Drives Extensive Forearc Mantle Wedge Hydration
AGU AdvancesHydration of the subduction zone forearc mantle wedge influences the downdip distribution of seismicity, the availability of fluids for arc magmatism, and Earth's long term water cycle.

Global Challenges, EarlyView.Rainwater harvesting (RWH) has become a hot issue in the present scenario due to intermittent climate change, scanty rainfall, and insufficient surface runoff. Among such, the Konso area in the extreme south of Ethiopia is considered to find effective sites for RWH through multi‐criteria analysis combined with Geographic Information System.

Uranium distribution in the Variscan Basement of Northeastern Sardinia [PDF]
, 2015 We present a detailed map of the uranium distribution and its uncertainties in the Variscan Basement of Northeastern Sardinia (VBNS) at a scale 1:100,000. An area of 2100 km2 was investigated by means of 535 data points obtained from laboratory and in situ gamma-ray spectrometry measurements.

Geological Journal, EarlyView.This work documents how the texture and composition of metamorphic garnet represent a valuable petrological archive capable of deciphering complex thermobaric histories. ABSTRACT In the central sector of the Sanandaj‐Sirjan zone of Iran, the Triassic‐to‐Jurassic ‘Hamedan Phyllites’ metamorphic complex shows a polymetamorphic evolution characterised by ...
