Mixed Carbonate-Siliciclastic Sequence Development and Chemostratigraphy On a Distal Foreland During Miocene Glaciation, Eastern Saudi Arabia
… the proximal foredeep in Iran. Deposition of the siliciclastics was driven by lowered sea levels, and moderately humid to arid climate. Rising sea levels pushed the siliciclastics updip allowing mixed siliciclastics and carbonates to form downdip, under semi-arid climate and locally hypersaline …

High-Resolution Sequence Stratigraphy of Late Mississippian (Chesterian) Mixed Carbonates and Siliciclastics, Illinois Basin
Eight 4th-order (~400 k.y.) disconformity-bounded mixed carbonate-siliciclastic sequences were deposited in the tectonically-active, tide-dominated Illinois basin during the Late Mississippian greenhouse to icehouse transition. Detailed, lithologic cross-sections were constructed through the …

Stratigraphic Analysis of the Capps Limestone in the North Norton Oil Field in Runnels County, Texas
… Member of the Mineral Wells Formation is a carbonate reservoir located in North Central Texas. It consists of interbedded limestone, sandstone, and shale units. Much of the Capps Limestone exists in the subsurface of Brown, Coleman, Runnels, Coke, Nolan, and Taylor counties, however, the …

GEOCHEMICAL ANALYSIS OF THE EAGLE FORD SHALE IN WEBB AND DIMMIT COUNTIES, TX
… Cretaceous Eagle Ford Shale of South Texas is a mixed carbonate–siliciclastic succession that serves as both a prolific hydrocarbon source and reservoir. This study integrates chemostratigraphy, mineralogical analysis, and elemental ratio proxies to reconstruct depositional environments and …

An Integrated Well Log and 3D Seismic Interpretation of Missourian Clinoforms, Osage County, Oklahoma
… sequence stratigraphic interpretation revealed a mixed carbonate-siliciclastic system comprising of delta, offshore shelf, and carbonate buildup depositional systems of mesothem, 3rd order sequence magnitude. The observed succession included: 1) falling stage to lowstand, sand-prone, subaqueous …

Reservoir Characterization of the Utica Shale Play Using Well Log Data in Columbiana, Ohio
… throughout the Appalachian Basin. The play is a mixed carbonate-siliciclastic system that grades from primarily carbonates at its base in the Lexington/Trenton limestones into primarily shale within the Utica shale. As of January 2021, it is the third highest-producing dry shale gas play in the …

The Aptian evolution of the Galve sub-basin (Maestrat Basin; E Iberia)
The epeiric mixed carbonate-siliciclastic sedimentary succession of Aptian stage (125-112 Ma) cropping out in the Galve sub-basin (western Maestrat Basin) in the eastern Iberian Chain (E Iberia) was analyzed by multiscale and multidisciplinary approaches. The integrated basin analysis presented in …

Petrogenesis of Pliocene limestones in southern Hawke’s Bay, New Zealand: a contribution to unravelling the sequence stratigraphy and diagenetic pathways of cool-water shelf carbonate facies
Among carbonate sedimentologists, it is now appreciated that shallow-marine carbonates are not restricted to warm-water tropical settings, but can also be produced on modern cool-water shelves outside tropical latitudes. In the last two decades, many publications have not only advanced our …
