Introduction and Background: The Mars Science Laboratory (MSL) CheMin instrument on the Curiosity rover is a transmission X-ray diffractometer (Co-K radiation source and a ~5 to ~52 2 range) where the analyzed powder samples are constrained to have discrete particle diameters <150 μm by a sieve [1]. To date, diffraction patterns have been obtained for one basaltic soil (Rocknest (RN)) and f...

Introduction: Recent researches are shedding new lights on the evolution of Valles Marineris and neighboring chaotic terrain and outflow channels. For example , Chapman and Tanaka [1] proposed a hypothesis with an emphasis on magma-ice interactions for the formation of chasmata, interior deposits, chaotic terrain , outflow channels, and surface materials. Terrestrial analog studies are useful i...

Sulfur isotope ratios are among the most commonly studied systems in geochemistry. While sulfur ratio analyses of materials such as bulk rock samples, gases, and sulfide grains routinely carried out, in-situ silicate glasses those formed magmatic relatively scarce literature. Despite a number attempts recent years to analyse volcanic experimental by secondary ion mass spectrometry (SIMS), effec...

Since May 2018 till the end of 2021, Mayotte island has been locus a major submarine volcanic eruption characterized by offshore emission more than 6.5 km 3 basanitic magma. The occurred along WNW–ESE trending ridge on east flank where, in addition, several seemingly recent phonolitic bodies were also identified close to island. To define realistic scenarios magma ascent and potentially predict...

1. Introduction The rather limited Neogene-Quaternary olivine basaltic lava flows are outcropped in the Dehaj-Javazm area, north of Share-Babak, in the NW of Dehaj-Sarduieh magmatic belt as a part of the Urumieh-Dokhtar magmatic assemblage (UDMA). The rocks contain significant amounts of plagioclase both as phenocrysts and microliths in the microlithic groundmass which play an important role i...

introduction in the east and northeast of sanandaj in the qorveh-bijar-takab axis, there are series of basaltic composition volcanoes with quaternary age. the study area is part of the sanandaj-sirjan zone and is located between 47°52' and 47°57' e longitudes and 35°26 and '35°30' n latitudes. due to the location of the volcanic cone on pliocene clastic sediments and quaternary travertine, the ...
