Coarsening-Upward Sequences in Beach Cusp Accumulations
Chafetz HS and Kocurek G. 1981. Coarsening-Upward Sequences in Beach Cusp Accumulations. Journal of Sedimentary Petrology. 51(4):1157-1161
Coarsening-upward sediment accumulations comprise horns of beach cusps on the upper foreshore of Big Shell Beach, central Padre Island, south Texas coast. The thicknesses of the coarsening-upward grain size sequences are about equaJ to the relative relief between the top of the horn and the adjacent embayment (approximlte1y 30 cm). These upward-coarsening trends are due to initial growth and/ or lateral migration of the coarser-grained sediment comprising the horns over the finer sediment of the adjacent bays.
