Intraformational conglomerate

i. A conglomerate in which the clasts are essentially contemporaneous with the matrix, developed by the breaking up and rounding of fragments of a newly formed or partly consolidated sediment (usually shale or limestone) and their nearly immediate incorporation in new sedimentary deposits; e.g., an edgewise conglomerate. Ref: AGI ii. A conglomerate occurring in the midst of a geologic formation, such as one formed during a brief interruption in the orderly deposition of strata. It may contain clasts external to the formation. The term is used in this sense esp. in England. Ref: AGI
