A preliminary assessment by the optical-mineralogical analysis can often be sufficient to solve production tasks, study raw composition, and choose a processing method at initial stages of technological researches. Such an will also help determine vector further studies. The material for primary mineralogical was waste sample from Kuznetskaya Central Processing Plant. We used during study. Fact...
The mineralogical composition and typological classification of a group 226 Axe-God pendants from the Jade pre-Columbian Culture Museum (from Instituto Nacional de Seguros) in San José (Costa Rica) was studied, using non-invasive characterization technique novel stylistic scheme. Possible composition-design correlations were examined through descriptive functional statistical analysis. This stu...
Using a wide range of modern mineralogical and physicochemical methods, representative collection human bones from seven burial grounds the Vychegda Permians 11th–14th centuries was studied. The microstructure bones, their chemical normative-mineral composition, content microelements, nanoporosity organo-mineral composite, composition properties bioanatite bone collagen were analyzed. Fundament...
The Dawn spacecraft mission has provided extensive new and detailed data on Vesta that confirm and strengthen the Vesta–howardite–eucrite–diogenite (HED) meteorite link and the concept that Vesta is differentiated, as derived from earlier telescopic observations. Here, we present results derived by newly calibrated spectra of Vesta. The comparison between data from the Dawn imaging spectrometer...
Little information is available on the provenance, evolutionary trend and characteristics of the loess deposits in northeast Iran. These deposits are thought to be related to Quaternary paleoclimate. Studies of mineralogical, surface textures and geochemical composition and trace elements in these loesses in Golestan Province suggest that they are mostly derived from felsic igneous rocks (grani...
Opalinus Clay is the shale currently under investigation as host formation for geological radioactive waste disposal in Switzerland. Its hydromechanical response has been widely studied, and experimental results show a range of values whose dispersion needs to be clarified. This work aims explain literature by correlating hydro-mechanical mineralogical variability tested specimens. Based on pub...
As part of the Cultural Resource Management (CRM) evaluation process, fifty (50) Woodland ceramic sherds were selected by the Ft. Bragg (North Carolina) archaeological staff. The sherds were chosen so that they might give a sense of the range of variation that may exist within a single drainage and the differences that may exist between the river drainages (Table 1). The three river drainages i...
