ABSTRACT The metamorphic zoning and geothermobarometry of the Ryoke metamorphic complex in the Yanai area, southwest Japan, show that its thermobaric structure was buffered by the dehydration melting of biotite. The temperatures over most of the area covered by the three high‐grade zones (8.5‐ to 19.0‐km depth) are consistent with those of the ...

An unusual authigenic origin for halloysite and gibbsite is reported in a stalactite from Agios Georgios Cave, Kilkis. This speleothem includes mostly pure calcite whereas minor areas of Mg-rich calcite and scarce dolomite are present in four growth ...

Mott–Schottky Analysis of Archaeological Etruscan Pottery
Mott–Schottky plots of the inverse of the square of capacitance versus applied potential is used to study archaeological pottery from the Etruscan site of Pyrgi in Santa Severa (Rome, Italy). The application of Mott–Schottky (MS) analysis to electrochemical impedance data recorded for microparticulate deposits of archaeological ceramic materials is ...

Geochemical Disequilibrium at the Brittle‐Ductile Transition
Abstract We investigate the microtextural, microchemical, and isotopic effects of late‐stage ductile deformation in quartzite mylonites and kyanite–muscovite–quartz veins from the Raft River shear zone (Utah). Quartz microstructures record pervasive disequilibrium, expressed by unannealed features including undulatory extinction, deformation lamellae ...

Muscovite dissolution kinetics as a function of pH at elevated temperature
Mineral reactivity can play an important role in fracture-controlled fluid networks where maintaining or increasing permeability is a goal, such as enhanced geothermal systems.

Abstract The Nanga Parbat–Haramosh Massif located in the northwestern syntaxis of the Himalaya is an antiformal structure considered as a crustal diapir undergoing exhumation at a rate larger than 10 mm/yr since 1 Ma. Using GNSS horizontal surface velocities and a vertical and east–west decomposition of the Sentinel‐1 interferometric line‐of‐sight ...
