The Gamla Bastnäs mine field (Old Bastnäs), is characterised by two variably skarn-altered calcitic or dolomitic marble horizons. The northern horizon stands out with its pronounced magnetite-bearing skarn assemblages, as either a tremolite-serpentine skarn or an actinolite-dominated skarn. Larger domains of unaltered marble are found within the southern skarn horizon with tremolite- or actinolite-rich skarn alteration or “ophicalcitic” marble (a dolomitic carbonate rock containing abundant serpentine pseudomorphs after olivine or humite-group minerals) occurring intermittently.
