Title: Environments
Interpreted from Exposures in Cane River Diversion Channel, Louisiana: ABSTRACT
Author(s):

Abstract:
A Miocene deltaic
sequence, 75 ft thick, is exposed continuously for 4 mi in the Cane River Diversion Channel 25 mi northwest of Alexandria, Louisiana. This outcrop permits a detailed study of the abrupt lateral and vertical variations of lithologic character, sedimentary structures, bed geometry, and diagenetic alterations in a prograding
deltaic
sequence. From this study, the sedimentary features of channels, point bars, levees, swamps, and distributary mouth bars have been characterized and compared with those of modern
deltaic
environments
.
Deltaic
paleoenvironments commonly are found in the subsurface, e.g., the oil producing Wilcox of central Mississippi and Louisiana. This study provides a model to aid in understanding the seemingly random occurrences of lithologie
and their related correlation problems of the subsurface.
