1937 Bull. Amer. Assoc. Petroleum Geologists 21 1596 Orogenesis means ‘mountain-making’, but the term refers only to the production of mountain structure, not to that of mountain topography. Hence, it seems desirable to replace it by ‘tectogenesis’, as Haarman suggested.
1965 Philos. Trans. (Royal Soc.) A. 258 74 Undisturbed marine successions do not necessarily rule out synchronous tectogenesis of a neighbouring region.
