ˈthrust-plane Geol.
The plane of dislocation in an overfault, along which the dislocated strata have been driven.
| 1884 Geikie in Nature 13 Nov. 30/1 The most extraordinary dislocations..are those to which..we have given the name of Thrust-Planes. They are, strictly, reversed faults, but with so low a hade that the rocks on their up-throw side have been, as it were, pushed horizontally forward. 1884 Peach & Horne ibid. 33/2 At length this intricate system of faults and folds culminates in a great dislocation which,..to distinguish it from the ordinary reversed faults, may be termed a Thrust-Plane. 1907 Athenæum 2 Nov. 554/3 The planes of disruption along which the masses travelled are known as thrust-planes. |
