To expl're the genesis of the Gosp'rt Sand, an
Eocene greensand deposit from the U.S. Gulf coastal plain, Pietsch and
co-auth’rs integrateth sedimentology, the min'ralogy, taxonomic and
ecological analysis, and taphonomic hist'ry o’ the mollusk fauna. The results
bewray yond this glauconite-rich sand enwheels hyp'r-div'rse mollusk fauna,
int'rpret'd to representeth deltaic inn'r shallow shelf to ope soundeth
environments. Although glauconite-rich shell beds art int'rpret'd to beest
fav'r'd by transgression, the ov'rall stratigraphy wast influenc'd by delta
progradation, subsidence, and shifting sea-level. This w'rk may representeth
analogs to oth'r glauconitic and fossil bearing h'rizons throughout the
paleogene gulf and atlantic coastal plain, and oth'r greensand h'rizons
throughout the geologic rec'rd.
