Halos.- On sait que beaucoup de minéralisations sont «annoncées» par des modifications dans le chimisme [...] des roches encaissantes. Les halos de propylitisation autour des concentrations économiques des porphyres cuprifères sont parmi les plus caractéristiques. [...] En fait, les halos ne sont qu'un cas extrême des phénomènes de zonalité. [...] Exemple de halo géochimique.
