... of the fulgurite were implemented in order to quantify the fusion behaviour, the expansion of the fulgurite as well as the distribution of the stressed quartz crystals. The study of the neutron diffraction pattern was carried out by applying an integral breadth method, more precisely a Rietveld and a LeBail strain...

... With the introduction of many new types of remotely sensed imagery in recent years, opportunities to compare and integrate these data abound. In this paper, we present a hue-saturation-value (HSV) transformation approach for the fusion of surface roughness and shallow subsurface information...

... land surface being exhumed by deflation and water erosion. The slabs of melt are associated with outcrops of baked sediment having very similar geochemistry, suggesting an origin by in situ surface fusion. Embedded clasts displaying shock metamorphism in quartz suggest that the thermal source may have...

...M. J. Genge; M. M. Grady Abstract The fusion crusts of meteorites form due to heating during atmospheric entry and have mineralogies which are strongly influenced by changes in oxidation state. We have studied the fusion crusts of the most reduced primitive meteorite group, the enstatite chondrites...

... and small-volume tuffs with the widespread outflow sheets of the SWNVF. New laser fusion 40 Ar/ 39 Ar isotopic ages are used to refine and revise the timing of eruptive activity in the SWNVF. The use of high-sensitivity mass spectrometry allowed analysis of submilligram-sized samples with analytical...

...S. Scaillet; G. Féraud; Y. Lagabrielle; M. Ballévre; G. Ruffet Abstract 40 Ar/ 39 Ar laser-probe dating of phengitic micas has been carried out by step-heating and spot-fusion procedures. These micas represent successive deformation stages in the structural evolution of the internal Dora Maira...

...J. Arkani-Hamed; Wayne T. Jolly Abstract Thermal evolution models of young subducting oceanic plates under Archean conditions suggest that tholeiitic basalts in the subducting wet crust melted at shallow depths (50 to 80 km) and produced Archean tonalites. The latent heat of fusion consumed...

... in which they occur, with some systematic variations, thus indicating in situ formation. The textures of the pseudotachylites indicate that they formed predominantly by mechanical processes, but temperatures were locally high enough to cause thermal metamorphism and possibly fusion. The host rocks...
