The archaeological visibility of hearths related to shellfish cooking methods is limited, particularly in pre-ceramic shell midden contexts. Important evidence for use fire the thermal alteration components, namely identification burnt shells. Mollusk shells that mineralize as aragonite are indicative burning due conversion calcite through recrystallization at known temperature thresholds. Howe...

Purpose. In the electronics industry, stibium (Sb) is an important element used in development of silicon-based devices. The metallogenic district Guelma, known for its polymetallic antimony mineralization, not currently exploited. research purpose to characterize minerals and gang formations elements required as dopants during growth monocrystalline silicon. Methods. methods include detailed g...

Marfan syndrome (MFS) is an inherited connective tissue disorder transmitted as an autosomal dominant trait. Recent studies indicate that decreased bone mineral density (BMD) occurs in the spine, femoral necks and greater trochanters of some adults and children with MFS. Since there is uncertainty regarding the BMD status of patients with MFS, the authors present a case report on a female patie...

Abstract In recent years, various geological activities and different mineral prospecting exploration programs have been intensified along the Red Sea hills in order to elucidate maps evaluate potentials. This study is therefore aimed at testing viability of using remote sensing geographic information system (GIS) techniques for mapping gold mineralization area. The area located northeast Sudan...

This work describes a knowledge-guided clustering approach for mineral potential mapping (MPM), by which the optimum number of clusters is derived form a knowledge-driven methodology through a concentration-area (C-A) multifractal analysis. To implement the proposed approach, a case study at the North Narbaghi region in the Saveh, Markazi province of Iran, was investigated to discover porphyry ...

CM chondrite is the most important carbonaceous containing abundant Ca, Al-rich inclusions (CAIs) and other interesting objects, which probably experienced early condensation processes in Solar Nebula environment later alteration parent body surroundings. Thus, it a vital raw material to explore formation evolution of System. Grove Mountains (GRV) chondrites have been collected from Antarctica ...

The reservoir rock ismade up of differentminerals which contribute to the overall formation wettability. These minerals in their natural state differ chemistry and structure, thus behave differently an environment varying composition salinity. have direct implications for enhanced oil recovery due water flooding, or wettability alteration long-term exposure brine. With being a complex system mu...

X-ray mapping is increasingly used in the geological sciences for qualitative observations of textures, mineral zoning, and element distribution among rock components [1-4]. We combine mapping with an aggressive program of image analysis in deepening our understanding of the early solar system through the analysis of chondritic meteorites [5, 6]. Chondrites are “sediments” that accreted in the ...
