1925D. C. Barton in Bull. Amer. Assoc. Petroleum Geologists IX. 1239 The salt is merely part of the peculiar type of fold called by Mrazec ‘diapir’ fold, or by Krejci ‘piercement’ folds (Durchspiessungsfalten). 1942M. P. Billings Structural Geol. xiv. 254 Salt domes are classified by some geologists into piercement domes and non⁓piercement domes, the former being discordant, the latter concordant. 1965A. Holmes Princ. Physical Geol. (ed. 2) ix. 206 Diapiric folds (also known as piercement folds). 1965E. Lehner et al. in G. J. Williams Econ. Geol. N.Z. xix. 337/2 It seems improbable that the Tertiary anticlinal structure[s] without piercement cores, or at a long strike distance away from them, could owe their shape solely to hidden diapirism (e.g., upward movement of the clay core without a breakthrough to surface), without at least some help from tangential forces. 1975Nature 29 May 393/2 Because of the circular exposure of evaporite surrounded by younger disturbed rocks, Haughton Dome has been considered a piercement dome. |
