Elemental Composition of the Martian Crust. The composition of Mars' crust records the planet's integrated geologic history and provides clues to its differentiation. Spacecraft and meteorite data no... McSween Jr.,Y Harry,Taylor,... - 《Science》 被引量: 319发表: 2009年 The Martian surface...
structure. Yet the costs and intensiveness of producing fused silica often mandate the use of alternative oxides such as alumina (Al2O3) or magnesia (MgO), and various additives like soda flux and lime stabilizers. This not only...
Probably this reflects the composition of the glacial sedi- ments, which is dominated by the presence of Ferrar rocks fragments. The identification of the main lithology in the composition of the Aeolian sediments (graph i, j Fig. 5) can't be carried out: the profiles are highly enriched ...
In this chapter, we review the contribution of space missions to the determination of the elemental and isotopic composition of Earth, Moon and the terrest
crust geochemistry[1] Quantifying secular variations in the chemical composition of the Martian crust provides unique insights into the processes that have guided the evolution of the Martian crust-mantle system. Using global abundances for a suite of elements determined by the Gamma Ray Spectrometer ...
Two of the sources have compositions that are similar to olivine and pyroxene-rich mafic cumulates with variable proportions of a Rb-enriched phase, such as amphibole, whereas the third source has the composition of liquid trapped in the cumulate pile (i.e. similar to KREEP) after similar ...
The crystalline structure and elemental composition of metals varies from grade-to-grade, corresponding to a wide variety of properties in terms of ductility, strength, weldability, and more. Modern process en...
