J. H. Teall Brit. Petrogr. Gloss. 448 Petrogeny, that department of geology which treats of the formation of rocks. 1937 N. L. Bowen in Amer. Jrnl. Sci. 233 1 In mixtures containing all of these (SiO2, Al2O3, iron oxide, CaO, MgO, Na2O and K2O) the residual liquid from fractional crystallization will show this same character of great enrichment in alkali-alumina silicate. Since the oxides listed above make up some 97 per cent of the composition of the average igneous rock the alkali-alumina silicate system (NaAlSiO4–KAlSiO4–SiO2) is here referred to as petrogeny's ‘residua system’. 1950 E. E. Wahlstrom Introd. Theoret. Igneous Petrol. i. 3 Petrogeny places emphasis on the manner of origin or genesis of rocks. 1990 Geol. Soc.
