Molybdenite is a common sulfide hosting many trace elements. Trace elements in molybdenite from individual deposits have been widely used to constrain the source and conditions of ore-forming fluids. However, relationship between element composition deposit types has not well investigated large dataset. Here, simple statistics partial least squares–discriminant analysis (PLS-DA) were determine ...

In this study, 115 samples taken from the stream sediments were analyzed for concentrations of As, Co, Cr, Cu, Ni, Pb, W, Zn, Au, Ba, Fe, Mn, Sr, Ti, U, V and Zr. In order to outline mineralization-derived stream sediments, various mapping techniques including fuzzy factor score, geochemical halos and fractal model were used. Based on these models, concentrations of Co, Cr, Ni, Zn, Ba, Fe, Mn, ...

Hyperspectral remote sensing records reflectance or emittance data in a large sum of contiguous and narrow spectral bands, and thus has many information in detecting and mapping the mineral zones. On the other hand, the geological and geophysical data gives us some other fruitful information about the physical characteristics of soil and minerals that have been recorded from the surface. ...

Abstract Copper isotope analysis has emerged as a promising tool for understanding genetic processes in Cu ore deposits. However, applications of this analytical technique to Archean deposits have been extremely limited, even though terranes are among the most economically endowed on Earth. As such, study presents first an deposit, Mesoarchean Carlow Castle hydrothermal Cu‐Co‐Au deposit. primar...

The west-central Sinai area includes one of the most productive manganese deposits in Egypt (Um Bogma Mn-Fe ore). explored is covered by a Carboniferous and Cambro-Ordovician sedimentary succession overlying Precambrian basement rocks. purpose this study to delineate geochemical anomalies ore related elements track their dispersion trains, which may lead discovery unknown deposits. For purpose,...

As for geology, Zlatý Chlum is a highly varied locality with frequent metaquarzit, amphibolite, quartz as well deposits of sulphideores. This work deals the use Acidithiobacillus ferrooxidans to bioleach polymetallic ores (Cu, al, Zn, and Fe) fromthis locality. Leaching lasted 5 weeks in bioreactor that ensured optimal conditions bioleaching. The results imply theexperiments were successful, le...

Abstract Pyrite geochemistry has proven useful for tracking changes in the composition and physico-chemical conditions of hydrothermal fluids ore-forming environments. Here, we investigated microtextural features chemical pyrite, a main Au-bearing phase Akeshi Kasuga deposits (Southern Kyushu, Japan), to better constrain processes these high-sulfidation epithermal Au deposits. Despite widesprea...
