in this study, we focused on detailed studies on micromorphological and mineralogical properties of three types of peat and swamp, to compare these different ecological area together. to achieve this goal, samples from a highland peat swamp (ghaleh-ghafeh ps), a peat swamp forest (suteh psf) and a costal swamp (galougah cs) in golestan province, north of iran have been considered. these studies...

Introduction: It has been theorized that the effects of space weathering during soil formation on the Moon are similar to those for many other airless bodies (e.g., Vesta, Eros) [1,2]. Therefore, the study of these effects on lunar soils may form the basis for our understanding of other heavenly bodies. This is a particularly valid axiom for reflectance spectroscopy of these soils. It has been ...

During carbon steel manufacture, slag residues are generated to remove material impurities from liquid metal and thus control the quality of carbon steel. As the utilization of secondary metallurgical slags is not as efficient as those of primary slags, a comprehensive characterization of steel ladle slag was performed. Pseudo-total concentrations of a wide range of elements were determined dur...

CheMin is a miniature X-ray diffraction/X-ray fluorescence (XRD/XRF) instrument that is included in the payload of the Mars 2009 Mars Science Laboratory mission. A portable CheMin prototype was built to test the capability of the instrument for remote in-situ mineralogical characterization of geological materials. The instrument was successfully deployed at a variety of Mars analog sites in Dea...

Remedial technologies utilized at hazardous waste sites for the treatment of metal and metalloid contaminants often take advantage of reduction-oxidation (redox) processes to reach ground water clean up goals (Barcelona and Holm, 1991; U.S. Environmental Protection Agency, 2002). This is because redox reactions, in many cases, govern the biogeochemical behavior of inorganic contaminants by affe...

The Montevive celestine mineral deposit, set in the Granada Basin a marine evaporitic uppermost Tortonian–lowermost Messinian sequence, is largest reserve Europe of this economically important strontium ore. Currently, mine has large amount tailings resulting from rejection manual dry screening high-grade mineral. This visual and density was carried out early days mining (1954–1973). Concentrat...
