Gossan is composed of hematite, goethite, clay minerals, brucite and sulfates
- bel">•
Gossan is significantly enriched with As, Pb, Sb, and Zn relative to barren ferricrust
- bel">•
Lead isotopic composition of gossan and barren ferricrust shows different values
- bel">•
Gossan is less depleted of 65Cu as compared with barren ferricrust
- bel">•
No differences were proved between the δ66Zn values in the gossan and in ferruginous crust
