Abstract

A detailed chemo-stratigraphic study has been performed for the Albian-Cenomanian Wara-Burgan complex of Greater Burgan Field, Kuwait to establish chemostratigraphic zonations as the foundation for a chemostratigraphic correlation framework. Furthermore, the framework provides an independent constraint on the stratigraphy of the Greater Burgan sequences that can be integrated with information relating to the lithostratigraphy, sedimentology, and biostratigraphy. Chemostratigraphy involves the characterization of sedimentary strata based on variations in their whole rock inorganic geochemistry, resulting in chemostratigraphic zonations being erected for the strata. Chemostratigraphy is particularly effective in siliciclastic successions with little biostratigraphic control, such as stacked sequences of fluvial sandstones. The success of the technique is due to the geochemical provenance signature of siliciclastic rocks, as reflected by the varying abundance of the relatively immobile elements, relatively unaffected by the processes of weathering, transport and diagenesis. The whole stratigraphic interval has been subdivided into 9 zonations defined by nine chemostratigraphic packages. Each package has internally consistent geochemical composition related to changes in detrital mineralogy and provenance. The zonations have been successfully combined to form an interwell chemostratigraphic correlation for the Burgan, Mauddud and Wara Formations. This chemostratigraphic zonation was subsequently used to constrain the sequence stratigraphic framework
