brachyanticline (a short anticlinal fold of layers of rock having an oval cross section. The layers of rock that form the brachyanticline slope away from the central portion of its crest on all sides. A brachyanticline is represented on a geological map in the form of concentric oval rings, with the older rocks located in the center; the rocks become progressively younger toward the periphery.
