II. 227 Chemical analyses by Pisani on fresh and scapolitized material from Pouzac show that the alteration is accompanied only by addition of sodium chloride. 1932A. Harker Metamorphism xvi. 255 This widespread scapolitization..is doubtless related to the mechanical conditions proper to regional metamorphism, which facilitate the permeation of the rocks by volatile bodies. 1936Nature 29 Feb. 366/2 Gabbroid rocks were intruded..and were followed by late-stage solutions which scapolitised the sediments, turned the gabbro into epidiorite and chloritised the Basement schists. 1954Jrnl. Geol. Soc. Australia I. 6 The current-bedded sediments are scapolitized calcareous rocks. a1965A. W. G. Whittle in G. J. Williams Econ. Geol. N.Z.
