Abstract
THERE is a well-known petrogenetical theory that rock-types, undersaturated in silica, can form from saturated magmas by limestone-syntexis1–4, or by the physico-chemically equivalent process of granite-assimilation by carbonatite magma5. Nobody, however, seems to have tried to verify experimentally such proposed processes. This may have been due to the fact that the shadow of the all-embracing crystallization-differentiation theory6 loomed large over the then still extremely small world of experimental petrologists. Petrographers, on the other hand, may have felt that their evidence (partial replacement of limestone- and dolomite-inclusions with concomitant formation of feldspathoids in lavas) was just as good as laboratory proof. Interesting evidence by McLintock7, who published an account of the generation of leucite and ægirite with melilite, wollastonite and diopside in a Persian marl, heated by the combustion of hydrocarbons underground, seems to have got little attention.
