Mineralogical features of placer gold and gold-sulfide ore occurrences the Sololi river basin from uplift Olenek arch have been studied. According to typomorphic indicators, two types are distinguished. The first type is a tabular lumpy shape, often with mineral indentation imprints. inner structure represented by granulation, recrystallization, high-grade intergranular veins, shells typical in...

Nome placer offshore gold grade estimation is a challenging problem in light of extreme ore heterogeneity. However, this type of phenomenon is quite common in placer ore grade variation. Further, the characterization of spatial ore grade variability and subsequent ore grade modelling of the deposit becomes problematic due to the unavailability of adequate samples. Being located in the Arctic, t...

We present the results of forward modelling of the Northern Alpine German-Austrian Molasse Basin, which forms part of the Northern Alpine Foreland Basin (NAFB) extending from Lake Geneva in the west to Lower Austria in the east. The observed deflection of the European plate under the NAFB has been modelled along five profiles perpendicular to the basin axis. Models treating the deflection of th...

Alluvial placer gold deposits that accumulate in streams across the globe are essentially allochthonous sedimentary transported from their source to location of deposition. The purpose this study was find alluvial sediments along Indus River NW Himalaya Pakistan. investigated region divided into five clusters based on river morphology. research focused mineralogical distribution, sediment sourc...

A comparative analysis of typomorphic features gold placers and indigenous sources was carried out for the Glukharinsky ore-placer node (the Nadezhda deposit Glukharinskoye, Tyomnoye, Tyi-Jurye ore occurrences). correlation between fineness placer native composition relic minerals preserved inside particles obtained first time. This made it possible to establish mineral parageneses from potenti...
