Is silt the most influential soil grain size fraction? [PDF]
, 2011 The contribution of individual grain size fractions (2000–500, 500–250, 250–63, 63–2 and < 2 μm) to bulk soil surface area and reactivity is discussed with reference to mineralogical and oxalate and dithionite extractions data.

Remote Sensing Analysis and LiDAR Experimenting in the Espique Valley (La Peza, Granada, Spain)
Archaeological Prospection, EarlyView.ABSTRACT The Espique valley is a small space at the foot of the mountain, practically closed, which hides a rich archaeological heritage, not only of habitats but also of varied productive spaces. For some years now, MEMOLab UGR has been carrying out research that is now enriched with the contribution of LiDAR, with whose application we are ...

Chemical Clues on the Formation of Planetary Systems: C/O vs Mg/Si for HARPS GTO Sample [PDF]
, 2010 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

Archaeological Prospection, EarlyView.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.

Mineralogy of northern nearside mare basalts [PDF]
, 2018 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 ...
