| 1927 L. W. Collet Struct. Alps i. vi. 20 The Morcles Nappe and similar parautochthonous folds. 1935 E. B. Bailey Tectonic Ess. iii. 34 In parautochthonous folds and thrust-masses (Arnold Heim) the travel of the rock has been considerable or great, according to ordinary standards, but small in the Alpine scale of magnitudes. 1962 Read & Watson Introd. Geol. I. x. 580 Parautochthonous granites have travelled only a short distance from their place of origin. 1963 J. G. Ramsay in Johnson & Stewart Brit. Caledonides vii. 166 It is not certain where these pieces have their roots. They might be parautochthonous folds, but some evidence seems to indicate that a few might represent the noses of nappes. |
