- W1987118052 abstract "Heavy mineral placer deposits of Pleistocene age in northeastern Florida were examined sedimentologically. Neither general setting, nor granulometric or mineralogic results are in agreement with a concentration of the heavy minerals in a beach, eolian or fluvial environment. Granulometric moment parameters of the ore sands seem to be distinctive. They include moderate sorting, high positive skewness, high kurtosis and a distinctive fine tail. Similarities of grain size curves of the placer sands with nearshore-offshore sands exist. Mineralogically the samples are more variable but always impoverished in epidote. This scarcity of epidote is atypical for eolian sediments in the study area, and the lack of garnet and the fineness of ore sands are uncommon for beach placers of northeast Florida. Underlain by dune ridges, which acted as obstacles on the shallow sea floor during the Penholoway transgression (1.3 ± 0.1 Ma B.P.), heavy minerals in the Boulogne and Green Cove Springs main ore body must have been concentrated in bars by the interplay of longshore and transverse bottom currents. Lighter heavy minerals were deposited in smaller nearshore bars closer to the former coast (Green Cove Springs small ore body) or in dunes of barrier islands (Green Cove Springs western ore body). As is true today, layers of noteworthy concentrations of economic minerals in the swash zone of Florida beaches were formed only rarely during storms, contrary to the coasts of Australia or India, where higher energetic conditions prevail. The proposed model of concentration of heavy minerals in certain outer nearshore bars has long been assumed but never been proven." @default.
