1957Jrnl. Geol. LXV. 231/1 Migliorini coined the term ‘resedimented rocks’ which is not entirely unambiguous but is nevertheless useful as a short way of referring to the deposits of turbidity currents. Ibid., Various types of markings on the sole of the graywackes..explaining them on the basis of resedimentation by turbidity currents. 1973Nature 26 Jan. 267/2 Because most coarse material resedimented from modern stable continental shelves passes down submarine canyons we interpret major occurrences of coarse resedimented material down slope of the Cambro-Ordovician shelf break as evidence of submarine canyon activity. Ibid. 268/1 Episodes of resedimentation occurred from soon after the inception of the miogeocline in Lower Cambrian times to the changes in sedimentary polarity..in Middle and Upper Ordovician times. 1978[see resuspension s.v. re- 5 a]. |
