1957 C. O. Dunbar & J. Rodgers Princ. Stratigr. vi. 119/2 We propose to restrict the term disconformity to the third type, in which two units of stratified rocks are parallel but the surface of unconformity is an old erosion surface of appreciable relief, and to introduce a new term paraconformity for the fourth type, in which the beds are parallel and the contact is a simple bedding plane.
1975 Nature 3 Jan. 15/1 Here we use the term unconformity to refer to a significant gap (demonstrated or inferred) in the stratigraphic record (disconformity or paraconformity).
1996 Science 23 Feb. 1093/3 Paraconformities inferred from biostratigraphic..age breaks.
