2015-12-16 · In the Bathurst Camp, it is important to know the association of sed-imentary rock units because VMS mineralization has specific lithologi-cal associations. Chemostratigraphic research has shown thatgeochemical features of these sedimentary rocks may be used to distin-guish formations, especially after alteration, deformation, and meta-morphism, and therefore can enhance stratigraphic and structuralinterpretations thus impacting exploration. These chemostratigraphicfeatures are of two types: immobile-element variations reflecting prov-enance of the terrigenous material, and mobile hydrothermal-hydroge-nous-element differences indicative of depositional paleoenvironment.Analogous with volcanic rocks, high-field-strength elements (HFSE),such as Al, Ga, Ti, Sc, Zr, Hf, Y, HREE, and Th and possibly Nb, Ta, Cr,and V are generally immobile in sedimentary rocks …
