Skarn considered to be proximal in relation to theore-forming, hydrothermal system is richer in As, Co, S, Y and Zn than distal skarn. Distal skarn is richer in Mg, Mn, Cu and Sr. Chemical zonations in terms of higher proximal Zn/Pb and distal Mn/Fe ratios are comparable to sulphide-rich rocks, skarn deposits andiron oreformations elsewhere.
