The Svärdsjö Zn-Pb-Cu deposit is situated in the heavily mineralised Bergslagen lithotectonic unit of Fennoscandian shield, south-central Sweden. Intense hydrothermal alteration followed by a strong overprint deformation and metamorphism during Svecokarelian orogeny complicate interpretation local geology. Integration whole-rock lithogeochemical petrographic methods has allowed mainly dacitic v...

the trace element contents on the surface originated from mineralization would depend to the thickness of the calcrete layer above the ore deposit on the surface. a very thick layer of calcrete may not allow for much dispersion of the elements of interest in the surface. these elements may be concentrated in non-magnetic and magnetic part of calcrete. based on the current research, mineralogica...

Exploration geochemistry continues to be a major contributor to mineral exploration programs at all scales. The decade has spanned a complete economic cycle in the minerals industry, during which there has been a change in exploration emphasis from the dominance of Au and diamonds to the addition of a range of base metals and the recent revival of U exploration. Increasing metal prices and the ...

Abstract Most conventional statistical methods aiming at defining geochemical concentration thresholds for separating anomalies from background have limited effectiveness in areas with complex geological settings and variable lithology. In this paper, median+2MAD as a method of exploratory data analysis (EDA) and concentration-area (C-A) fractal model as two effective approaches in separation g...

Abstract Bimodal volcanism occurs in a range of extensional environments that are characterized by distinctive but overlapping, lithogeochemical and isotopic signatures lithological assemblages. Where basaltic magmatism is associated with ferroan (A‐type) rhyolites, it typically the lithogeochemistry systematics rocks most beneficial constraining tectonic evolution. This study presents geochemi...

Stikine Terrane arc rocks in the re,:ion host !;(m:ral copper-gold and copper-molybdenum ocnlwerlces (MINFILE 104 G and H). The volcrrnic strat.i,:raphy hosting these deposits is, however, poorly const:aimd. The Tatogga Lake project will attemp; to characterize individual deposits, desclibe their h a 1 and rcgictnal stratigraphic and structural settings, and deternme the ages of magmatism ...
