摘 要：<正>In this paper we present petrology and geochemistry from a range of metasomatically altered rocks within the Eastern Gawler Craton mineralised province of South Australia.The rocks represent four protolith types;granite,basalt,non-carbonate metasediment and calc-silicate metasediment.Alteration paragenesis varies in intensity and between the protolith types.I.The alteration paragenesis of granites has the first pervasive chlorite and the second filled hematite with two generations of chalcopyrite.After the third
