Physics of Solid and Liquid Alkali Halide Surfaces Near the Melting Point
, 2005 This paper presents a broad theoretical and simulation study of the high temperature behavior of crystalline alkali halide surfaces typified by NaCl(100), of the liquid NaCl surface near freezing, and of the very unusual partial wetting of the solid ...

ENSTATITE OF OPHIOLITE ULTRAMAFIC ROCKS: PLASTIC DEFORMATION AND RELATED CHEMICAL CHANGES [PDF]
Минералогия, 2018 The results of study of plastically deformed enstatite from mantle peridotites of the Central Kraka massif (South Urals) are presented. A case of orientation of stress field of peridotite unfavorable for activation of a single possible slip system of ...

Geochemistry, Geophysics, GeosystemsHigh heat fluxes occurring in rift settings are expected to generate partially melted low‐pressure–high‐temperature granulites (LP–HTG). Therefore, studying these rocks can offer valuable insights into crustal reworking during extension.

Backstepping Control of the One-Phase Stefan Problem
, 2016 In this paper, a backstepping control of the one-phase Stefan Problem, which is a 1-D diffusion Partial Differential Equation (PDE) defined on a time varying spatial domain described by an ordinary differential equation (ODE), is studied. A new nonlinear

The geology and petrogenesis of the southern closepet granite [PDF]
The Archaean Closepet Granite is a polyphase body intruding the Peninsular Gneiss Complex and the associated supracrustal rocks. The granite out-crop runs for nearly 500 km with an approximate width of 20 to 25 km and cut across the regional metamorphic ...

Petrology of silicate inclusions in the Miles IIE iron [PDF]
, 1996 The Miles IIE iron contains many silicate inclusions with gabbroic and cryptocrystalline textures. The gabbroic inclusions consist of inverted pigeonite, orthopyroxene, high-Ca pyroxene, olivine, sodic plagioclase, antiperthite, K-feldspar, tridymite ...

Bicontinuous microstructure formation through partial melting
Scripta MaterialiaLiquid-metal dealloying generates porous metals or interpenetrating-phase composites. Particularly attractive is the use of the alloy's innate melt for activating dealloying throughout the bulk, even in extended sample geometries, during reverse peritectic melting.

Formation of silicic crust on early Earth and young planetary bodies in an Iceland-like setting
Communications Earth & EnvironmentFour billion years ago, Earth’s surface was covered with a thick basaltic crust and, similar to other rocky planets and the Moon, parts of this basaltic crust underwent partial melting to produce silicic crust.
