Atokan-age units in the Permian Basin record a 2-order transgression, with aerially restricted, lower Atokan fluvial to shallow-marine siliciclastics followed by pervasive carbonate deposition. In general, Atokan-age siliciclastics dominated deposition in the west of the Permian Basin while carbonate deposition dominated throughout the rest of the basin. Predominance of carbonate facies across ...

The Ediacaran-Cambrian transition interval is described for the west part of Gondwana Supercontinent. This key in Earth’s history recorded upper and lower Tagatiya Guazú Cerro Curuzu formations, Itapucumi Group, Paraguay, encompassing a sedimentary succession deposited tidally influenced mixed carbonate-siliciclastic ramp. remarkable presence cosmopolitan Ediacaran shelly fossils treptichnids, ...

The Cisco Group on the Eastern Shelf of the Midland Basin is composed of fluvial, deltaic, shelf, shelf-margin, and slope-tobasin carbonate and siliciclastic rocks. Sedimentologic and stratigraphic analyses of 181 meter-to-decimeter-scale depositional sequences exposed in the up-dip shelf indicated that the siliciclastic and carbonate parasequences in the transgressive systems tracts (TST) are ...

Abstract This paper presents the facies and depositional environment of early Miocene Dam Formation, Eastern Arabian platform, Saudi Arabia. Deposition Formation (Fm.) was considered as a restricted shallow marine deposition. Few studies suggest role sea-level change in its deposition but were without decisive substantiation. Here, we describe high-resolution model Fm. under varying conditions....

The Campo section in the Spanish Pyrenees is classical for shallow-water Paleocene-Eocene Thermal Maximum (PETM) studies. Despite extensive work last decades, stratigraphic location of onset negative carbon isotope excursion (CIE), and hence Paleocene/Eocene (P/E) boundary, remains a matter considerable debate section. Here we present new biostratigraphic, sedimentological carbon-isotopic data ...

2016 desert symposium e Bouse Formation provides a sedimentary record of the rst arrival of the Colorado River, water and sediment, as it was integrated from the Colorado Plateau to the Gulf of California 5–6 Ma. is unit is generally thin (10–100s m) but widespread within basins in the lower Colorado River corridor that extend from Lake Mead to Yuma (Fig. 1). e basins are interpreted to have be...

Three different outcrops are selected in this study, each representing a shallow-marine system with varying heterogeneity provided by siliciclastic–carbonate mixing that may form small or large stratigraphic trap. The impact of these styles mixed facies on CO 2 storage is relatively poorly known. This study demonstrates the significance systems for safe geological storage, as traps likely to be...
