| Abstract | Geochemical differences between footwall and hanging wall volcanic and sedimentary rocks hosting the Heath Steele B-B5 zone massive-sulphide deposits indicate that revision of previous stratigraphic and
structural interpretations is necessary. The lower footwall sedimentary rocks have high transition metal contents (Cr > 40 ppm) compared to upper footwall sedimentary rocks (Cr < 30 ppm); the former are chemically similar to the Miramichi Group,
whereas the latter resemble tuffaceous rocks of the Tetagouche Group. There are also immobile trace-element differences between the stratigraphic footwall and hanging wall crystal tuffs/tuffites; the hanging wall crystal tuffs have Zr/TiO2 ratios
greater than 0.05, whereas the footwall crystal tuffites have lower values. Furthermore, Y and Th contents are higher in the hanging wall than the footwall crystal tuffites, although the continuum for Y and Th indicates that the felsic volcanic units
are related. |
