Geochemical lithogenes have been successfully applied as an innovative concept in the field of composition classification and source traceability geological materials recently. This paper introduces background development geochemical genes construction application LG01 LG03 lithogenes. Based on LG03, LG_CR provenance are verified a weathering profile, ten gully sedimentary profiles regional str...

This paper describes the application of a new multi-criteria decision making (MCDM) technique called fuzzy outranking to map prospectivity for porphyry Cu Mo deposits. Various raster-based evidential layers involving geological, geophysical, and geochemical geo-data sets are integrated for mineral prospectivity mapping (MPM). In a case study, 13 layers of the Now Chun deposit located in the Ker...

This article presents evidence demonstrating that the historical use of leaded gasoline and lead (Pb) in exterior paints in Australia has contaminated urban soils in the older inner suburbs of large cities such as Sydney and Melbourne. While significant attention has been focused on Pb poisoning in mining and smelting towns in Australia, relatively little research has focused on exposure to Pb ...
