In a ground-interacting nuclear explosion, elements derived from environmental and anthropogenic material, such as iron, silicon, aluminum, can be incorporated into the fireball. When significant amounts of metals are entrained, resulting melt may display immiscible textures. The composition these textures is record temperature formation cooling rates (or thermodynamic stability) melts provide ...

In the preceding paper (Paper I) we discussed the thermodynamic and microscopic transport properties of hydrogen-helium fluid mixtures. These results are used in the present paper for a semiquantitative analysis of the thermal and compositional history of an evolving hydrogenhelium planet such as Jupiter or Saturn. First, the evolution of a homogeneous planet with no first-order phase transitio...

Archean greenstone belts contain low grade metamorphic volcanic sequences with localised examples of preserved original textures and relict magmatic minerals, which are invaluable for inferring processes by extension magma genesis. A feature observed in many but rare modern rocks is variolitic texture millimetre- to centimetre-sized leucocratic globular structures (varioles), mafic lavas. Model...

We report here a study of the cause of the coloration of blue zhamanshinites, which are glassy impact melt rocks from the Zhamanshin crater in the USSR. We find that the blue color results from Rayleigh scattering from spherical, 100 nm-diameter inclusions of a separate Ca-Fe-Mg-P-rich silicate glass. These observations can best be explained by the operation of liquid immiscibility in the zhama...

Molten system Na3AlF6 ? SiO2 was examined by high temperature NMR. Further characterizations of the samples prepared Rapid Solidification Processing (RSP) technique and spontaneous solidification were performed X–ray diffraction solid state The solubility in molten cryolite immiscibility phenomenon observed. Using thermogravimetric analysis, weight losses detected, which could be attributed to ...

Abstract In peel, tests between polycarbonate/polyethersulfone (PC/PES) blends with different compositions and thermoplastic polyurethane (TPU) films thicknesses a large decrease in energy release rate is observed when the PC/PES formed co‐continuous structure. With SEM analysis, XRD measurements, selective PC etching of failed samples, finite element modeling stress distributions region this f...
