G. Bonney in Q. Jrnl. Geol. Soc. 42 i. 95 Subsequent work..has thrown additional light upon the..kind of cleavage..in which the cleavage-planes cut across the undulating bands of the constituent minerals. Of this structure I possess one or two excellent examples..which makes it clear that the structure is an example of the strain-slip cleavage (Ausweichungs-Clivage) of Dr. Heim. 1903 A. Geikie Text-bk. Geol. (ed. 4) 681 Frequently the puckerings have been ruptured and a fine cleavage or jointing has been produced (Ausweichungsclivage, strain-slip cleavage). 1954 J. F. Kirkaldy Gen. Princ. Geol. x. 127 Less perfectly graded rocks..may develop not the true slaty cleavage, due to re-orientation of the minerals, but a strain-slip cleavage, produced by closely spaced planes of movement. 1969 G. M. Bennison & A. E. Wright Geol. Hist. Brit. Isles vii. 137 The first thrusts have been folded by N-S fairly open folds and associated asymmetric small folds have a strain-slip cleavage. < as lemmas |
