LSU Master's Theses

This study reports the results of a heavy mineral analysis of samples from Pecan Island and associated ridges on the Louisiana Chenier Plain. The goal of the study is to provide additional insight on the origins of the sand comprising the ridges. Chenier plains are multi-membered, progradational ridge-interridge mudflat sequences (Augustinus, 1989). The various suggested sources of the sand grains include: the Mississippi River, especially the Teche sub-delta; the Mermentau and Calcasieu Rivers; and the reworking of older mudflat and chenier ridges. Several liters of sand were collected from a depth of 0.5 to 2.0 meters at locations near the …
