Martian soil component in impact glasses in a Martian meteorite

Geophysical Research Letters, 1999
Chemical compositions of impact melt glass veins, called Lithology C (Lith C) in Martian meteorite EET79001 were determined by electron microprobe analysis. A large enrichment of S, and significant enrichments of Al, Ca, and Na were observed in Lith C glass compared to Lithology A (Lith A). The S enrichment is due to mixing of plagioclase‐enriched Lith

Oxygen Isotopes and Volatiles in Martian Meteorite [PDF]

, 2013
Oxygen isotopes were measured in mineral separates from martian meteorites using laser fluorination and were found to be remarkably uniform in both δ18O and Δ17O, suggesting that martian magmas did not assimilate aqueously altered crust regardless of any

Icelandic analogs to Martian flood lavas [PDF]

, 2004
We report on new field observations from Icelandic lava flows that have the same surface morphology as many Martian flood lava flows. The Martian flood lavas are characterized by a platy-ridged surface morphology whose formation is not well understood ...

The Formation of the Martian Moons [PDF]

, 2020
Abstract The origin of the natural satellites or moons of the solar system is as challenging to unravel as the formation of the planets. Before the start of the space probe exploration era, this topic of planetary science was restricted to telescopic observations, which limited the possibility of testing different formation scenarios.

Extraction of polar and nonpolar biomarkers from the martian soil using aqueous surfactant solutions [PDF]

, 2012
The Life Marker Chip intends to use an aqueous surfactant solution to extract both polar AND nonpolar biomarkers from the martian soil for transport to an antibody-based detection system. Currently, a solution of 1.5 g l-1 polysorbate 80 in 20:80 (vol:

Mineralogical characterization of Martian Jezero crater from MRO CRISM hyperspectral images [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014
Martian mineral detection and mapping can provide important information and constraints on Martian aqueous history, which can be used to assess the potential habitability of Mars.

Is the Martian crust also the Martian elastic lithosphere? [PDF]

Journal of Geophysical Research: Planets, 2002
Correlations between topography, gravity, and areoid on Mars are used to constrain the crustal and lithospheric thicknesses on the planet. Assuming that the Hellas basin is in isostatic equilibrium with Airy compensation, point correlations between areoid anomalies and topography are used to obtain the mean crustal density and the crustal thickness. We

The Environmental Education Dimensions for Sustainable Development

Journal of Legal Studies, 2015
Based both on a historical approach regarding the evolution of the environmental education between 1960 and present days, and on empirical research as well, the author proves that the efficiency of the environmental education could be much higher if ...
