introduction the study area is located 12km away from the north east of sarbisheh at the eastern border of the lut block (karimpour et al., 2011; richards et al., 2012). the magmatic activity in the lut blockhas begun in the middle jurassic (165-162 ma) and reached its peak in the tertiary age (jung et al., 1983; karimpour et al., 2011). volcanic and subvolcanic rocks in the tertiary age cover ...

Introduction: The lunar meteorites Miller Range 05035 (MIL) and Meteorite Hills 01210 (MET) were collected during the 2005 and 2001 ANSMET (Antarctic Meteorite Search) field seasons [1,2]. MET is a 22.8 g regolith breccia composed primarily of basaltic material [3-6]. MIL is a 142.2 g coarse-grained basalt [2]. The bulk composition, mineral assemblage, and texture of MIL is similar to lunar met...

Areas of exposed basalt along mid-ocean ridges and at seafloor outcrops serve as conduits of fluid flux into and out of a subsurface ocean, and microbe-mineral interactions can influence alteration reactions at the rock-water interface. Located on the eastern flank of the East Pacific Rise, Dorado Outcrop is a site of low-temperature (<20°C) hydrothermal venting and represents a new end-member ...

Introduction: Sedimentary rocks in Gale Crater on Mars indicate a varied provenance with a range of alteration and weathering [1, 2]. Geochemical trends identified in basaltic and alkalic sedimentary rocks by the Alpha Particle X-ray Spectrometer (APXS) on the Mars rover Curiosity represent a complex interplay of igneous, sedimentary, weathering, and alteration processes. Assessing the relative...

Introduction: Olivine vitrophyres are impact melts, consisting of Lunar highlands and KREEP-rich materials, that are primarily composed of olivines in an opaque glass, sometimes with lath-like plagioclase crystals [e.g. 0-2]. Petrographically, these are similar to vitrophyric Apollo 14 high-Al basalts [11]. The purpose of this study was to use olivine chemistry and petrographic evidence in orde...

Managing the rapidly changing saline-alkali land under cultivation in the coastal areas of China is important not only for mitigating the negative impacts of such land on the environment, but also for ensuring long-term sustainability of agriculture. In this light, setting up rapid monitoring systems to assist decision-making in developing sustainable management plans is therefore an absolute n...

Several studies of internal fiiction have been performed on silicate glasses. This work has the specificity to refer to isothermal mechanical spectroscopy over a large frequency range and for temperatures between 290 K and 520 K. Experiments were carried out with a single alkali silicate glass and two mixed alkali silicate glasses in order to observe the mixed alkali effect, to follow its evolu...

Introduction: Assimilation has been called upon in numerous occasions to explain various petrologic and geochemical observations of the igneous rocks on the Moon. A well known example is the assimilation of ilmenite-bearing late cumulates (and KREEP) to the low Ti primary magmas at shallow levels, that has been used to explain the high Ti magmas observed on the lunar surface [1]-[3]. An alterna...
