Variations in Melt Productivity and Melting Conditions along SWIR (708E^498E): Evidence from Olivine-hosted and Plagioclase-hosted Melt Inclusions
Melt inclusion and host glass compositions from the eastern end of the Southwest IndianRidge showaprogressive depletion in light rare earth elements (LREE), Na8 and (La/Sm)n, but an increase in Fe8, from the NE (648E) towards the SW (498E).These changes indicate an increase in the degree of mantle melting towards the SWand correlate with a shallowing of the ridge axial depth and increase in cru...
متن کاملHydrothermal jarosite and hematite in a pyroxene-hosted melt inclusion in martian meteorite Miller Range (MIL) 03346: Implications for magmatic-hydrothermal fluids on Mars
Low-temperature aqueous processes have been implicated in the generation of jarosite and hematite on the martian surface, but little is known regarding the role that high-temperature magmatic fluids may have played in producing similar assemblages on Mars. We have identified jarosite and hematite in a clinopyroxene-hosted melt inclusion in martian meteorite MIL 03346 that shows evidence of havi...
متن کامل‘ballen Silica’ in Impactites and Magmatic Rocks
Introduction and background: Ballen silica, in the modification of α-quartz (‘ballen quartz’) or α-cristobalite, has been regarded as an impactcharacterstic microscopic feature for decades. The report of ballen silica in impact melt rocks from the Mien impact structure (Sweden; the impact melt rocks were formerly considered as rhyolites) was the first description of ballen silica in impactites ...
متن کاملChemical zonation in olivine-hosted melt inclusions
Significant zonation in major, minor, trace, and volatile elements has been documented in naturally glassy olivine-hosted melt inclusions from the Siqueiros Fracture Zone and the Galapagos Islands. Components with a higher concentration in the host olivine than in the melt (e.g., MgO, FeO, Cr2O3, and MnO) are depleted at the edges of the zoned melt inclusions relative to their centers, whereas ...
متن کاملMagmatic interactions as recorded in plagioclase phenocrysts of quaternary volcanics in SE Bam (SE Iran)
In the southeast of bam, there is a collection of volcanic rocks with andesite, basalt and trachy andesite composition. The texture of these rocks are often porphyritic with microlithic, porphyric cavity, and sometimes glomerulophorphuri, sore throat trachytic. Main minerals include Olivine, Clinopyroxene, Plagioclase and secondary minerals including opaque minerals, Iodenzyte, secondary Biotit...
