tectogenesis Geol.|tɛktəˈdʒɛnɪsɪs|
[ad. G. tektogenese (E. Haarman 1926, in Zeitschr. f. Deutsch. Geol. Ges. LXXVIII. B. 106), f. Gr. τέκτων, -ον- carpenter, builder: see -genesis.]
The formation of the highly distorted rock structures characteristic of mountain ranges, as distinct from the formation of mountainous topography itself. Hence tectogeˈnetic, tectoˈgenic adjs., of, pertaining to, or involving tectogenesis. Also ˈtectogene [ad. G. tektogen (E. Haarman 1926, loc. cit., 107): see -gen 3], a long, narrow belt of downwarping in the earth's crust, said to be an underlying feature of mountain ranges and oceanic trenches.
1937Bull. Amer. Assoc. Petroleum Geologists XXI. 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. Ibid., Tectogenic movements..are incongruent, making stuctures that vary in the different stories of the crust; and the deformation they produce is wholly irreversible. 1937Leidsche Geol. Med. VIII. 204 (caption) Tectogene with root. 1965Phil. Trans. R. Soc. A. CCLVIII. 65 The later Palaeozoic..tectogene stretched in a belt from the Appalachians, through southern Britain and central and southern Europe, to Suess's massive Altaids in the heart of Asia. Ibid. 68 Throughout the Caledonides (Spitzbergen, Greenland, Scandinavia and Britain) there seems little doubt that the main tectogenic phase was centred in Silurian time. Ibid. 74 Undisturbed marine successions do not necessarily rule out synchronous tectogenesis of a neighbouring region. 1975Nature 24 Jan. 257/1 Sicilian data indicate a time span of only 3–4 Myr for a single ‘tectogenetic cycle’. Ibid. 10 July 116/1 The radial pattern of transverse folds with respect to the arc..has been taken into account in tectogenetic models of the Alps. |
