Cornstone

Abstract

Two dissimilar rocks have been confused under the title “cornstone”: one is a concretionary limestone, the other a calcareous conglomerate. A return to the names “concretionary cornstone” and “conglomeratic cornstone” is advocated since the rocks differ in their significance. Conglomeratic cornstones, intra-formational in character, point to sudden increases in current activity. Concretionary cornstones suggest declines in the supplies of clastic detritus.
