Chemical Clues on the Formation of Planetary Systems: C/O vs Mg/Si for HARPS GTO Sample [PDF]
Theoretical studies suggest that C/O and Mg/Si are the most important elemental ratios in determining the mineralogy of terrestrial planets. The C/O ratio controls the distribution of Si among carbide and oxide species, while Mg/Si gives information about the silicate mineralogy. We present a detailed and uniform study of C, O, Mg and Si abundances for

ABSTRACT The burial mounds of the early Iron Age, which we will refer to below as kurgans, from the nomadic equestrian warriors of Eurasia, form a very complex group of archaeological monuments. Archaeological excavations in Aržan 2 (Siberia) and Aleksandropol (Ukraine) show that the large burial mounds are complex architectural constructions.

Coal rock image recognition method based on improved CLBP and receptive field theory
In view of the evident differences between coal and rock in visual attributes such as color, gloss, and texture, the complete local binary pattern (CLBP) image feature descriptor is introduced for coal and rock image recognition, and the original algorithm oversimplifies local texture features by ignoring imaging information from higher‐order pixels ...

MINERALOGY OF THE OVERBURDEN ROCKS OF THE KOKLAN W-MO DEPOSIT (SOUTH URALS) [PDF]
The Koklan W-Mo deposit is overlapped by Mesozoic-Cenozoic rocks 120–140 m thick, which may be subdivided in four members on the basis of variable proportions of the rock-forming minerals (quartz, hydromica (with glauconite), smectites and X-ray ...

Mineralogy of northern nearside mare basalts [PDF]
The mineralogy of mare basalts reflects the chemical composition of the magma source, as well as the physical and chemical environment of the rock's formation. It is significant for understanding the thermal evolution of the Moon. In this study, the spatial distribution of the mineralogy of the lunar northern nearside basalts was mapped using the Moon ...
