(El Reno Group) LAWTON- "Dog Creek Shale," Pdc, reddish-brown silty shale, 85 to 190 feet (26 to 58 m) thick.Shale is mostly made up of clay, so it can range in color from medium brown to white. Shale is often used to make ceramic tiles. Shale colors fall in the neutral color palette and can be paired with blues for a country look, soft pinks for ...Shale: finely fissile; may include much silt Clay Shale (Argillaceous shale): chiefly clay minerals Argillite: highly indurated; incipiently recrystallized Bentonite: swells and disaggregates in water. Silica ... Carbonaceous Shale, Etc.: carbonized remains Bituminous Shale (Oil Shale) Etc.: sapropelic: Miscellaneous Phosphate (Collophane)Nov 14, 2002 · Early Pliocene clay, silty clay, and very fine argillaceous sandstones comprise the middle unit (1800 to 2341 mbsl). The lower unit (2341 to 3406 mbsl) is late Miocene (possible middle Miocene from 3170 mbsl) shaly and silty shale sediment.

The presence of shelly limestone indicates shallow, warm, silt-free and clean marine environment. The intact shells of bivalves suggest deposition in a low energy protected shoreline where wave action is limited. Sedimentary structures like fissility and laminations, also suggest deposition in low energy marine setting. ... Oil Shale, 2005, Vol ...It consists primarily of grey to rusty brown dolomitic and calcareous quartz siltstone, with interbeds of silty sandstone, silty dolomite, mudstone, shale, carbonaceous shale, and minor fine-grained quartz sandstone. Cross-bedding and ripple marks are common in its strata. The Sulphur Mountain Formation is subdivided into the following members:Shale CO 2 wettability is a key factor which determines the structural trapping capacity of a caprock. However, the influence of shale-total organic content (TOC) on wettability (and thus on storage potential) has not been evaluated despite the fact that naturally occurring shale formations can vary dramatically in TOC, and that even minute TOC strongly affects storage capacities and ...Silt, siltstone, or silty shale 617 Calcareous siltstone 618 Dolomitic siltstone 619 Sandy or silty shale 620 Clay or clay shale 621 Cherty shale 622 Dolomitic shale 623 Calcareous shale or marl 624 Carbonaceous shale 625 Oil shale 626 Chalk 627 Limestone 628 Clastic limestone 629 Fossiliferous clastic limestone 630 Nodular or irregularly ... Aug 2, 2022 · The shales were divided into massive silty shale facies, laminated paste shale facies, and laminated gray shale facies according to the mineral composition and microstructure. Comparing the geochemical characteristics, the laminated calcareous shale lithofacies of the deep to semi-deep lacustrine environments favor shale oil and gas occurrence.

medium-grained, quartzose to arkosic silty sandstone. Sand grains subrounded to subangular, 75-80% quartz, 15-20% feldspar, less than 15% mafic minerals (Hall, 1973). …The close--up view shows silvery flecks of muscovite. Although these are sand-sized, the bulk of the rock is silt- and clay-sized and thus is a shale. This is a red shale with greenish mottling. Both colors indicate iron oxide coatings on the clastic grains. Mar 24, 2023 · Brittleness is important in the evaluation of the fracturing ability of shale reservoir and has a significant impact on shale gas exploration and development. This paper discusses the characteristics and controlling factors of brittleness of continental shale in the Da’anzhai Member of the Ziliujing Formation of Lower Jurassic age in the northeast Sichuan Basin. Continental shale lithofacies ...

Contains a middle, gray silty clay unit, and interbeds of gray to dark-gray shale in the upper portion. Thickness up to 450 ft (137 m). The Eden series consists of moderately deep, well drained, slowly permeable soils that formed in residuum from interbedded calcareous shale, siltstone, and limestone.
