Abstract
The calcic skarn of Arroyo Zancado (Fig.1) evolution from a initial piroxenic stage, diopsidic in composition, to a complex ferric skarn with attending ore deposition of magnetite together andradite, hastingsite and idocrase (see tables 1 to 4) with epidote and allanite as accessories. There is a retrograde evolution in the hidrotermal conditions od skarn genesis, probably with slight changes in the acidity of the penetrating solutions. idtermal
