Book excerpt: The Pennsylvanian Marble Falls Formation in the Llano Uplift region of the southern Fort Worth Basin (Central Texas) is a Morrowan-Atokan mixed carbonate-siliciclastic unit whose deposition was influenced by icehouse glacioeustatic sea-level fluctuations and foreland basin tectonics. Previous interpretations of the Marble Falls Formation focused on outcrop data at the fringes of the Llano Uplift. This study uses a series of 21 cores to create a facies architectural model, depositional environmental interpretation, and regional sequence stratigraphic framework. On the basis of core data, the study area is interpreted to have been deposited in a ramp setting with a shallower water upper ramp area to the south and a deeper water basin setting to the north. Analysis of cores and thin sections identified 14 inner ramp to basin facies. Dominant facies are: (1) burrowed sponge spicule packstone, (2) algal grain-dominated packstone to grainstone, (3) skeletal foraminiferal wackestone, and (4) argillaceous mudstone to clay shale. Facies stacking patterns were correlated and combined with chemostratigraphic data to improve interpretations of the unit's depositional history and form an integrated regional model. The Marble Falls section was deposited during Pennsylvanian icehouse times in a part of the Fort Worth Basin with active horst and graben structures developing in response to the Ouachita Orogeny. The resulting depositional cycles reflect high-frequency sea-level fluctuations and are divided into 3 sequences. Sequence 1 represents aggradational ramp deposition truncated by a major glacioeustatic sea-level fall near the Morrowan-Atokan boundary (SB1). This fall shifted accommodation basinward and previously distal areas were sites of carbonate HST in Sequence 2 deposition following a short TST phase. Sequence 3 represents the final phase of carbonate accumulation that was diachronously drowned by Smithwick siliciclastics enhanced by horst and graben faulting. These findings contribute to our understanding of the depositional response to glacioeustatic sea-level changes during the Pennsylvanian and can also form the basis for constructing a sedimentological and facies analog for Morrowan to Atokan shallow- to deepwater carbonates in the Permian Basin and the northern Fort Worth Basin.

This book was released on 2018 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: THE PARADOX Basin is a northwest-southeast trending intracratonic basin that formed in southwestern Colorado, southeastern Utah and adjacent parts of Arizona and New Mexico during the late Paleozoic Era. During rise of the adjacent Uncompahgre Uplift (Ancestral Rocky Mountains) the rapidly subsiding basin was filled with over 2000 m of Permo-Pennsylvanian sediments. Stacked depositional sequences accumulated in three roughly parallel facies belts: a northeastern clastic belt (adjacent to uplift), a central salt and black shale belt, and a southwestern carbonate belt. Over 400 million barrels of oil have been extracted from upper Paradox (Desert Creek and Ismay) carbonates in the southern Blanding Subbasin (Greater Aneth Field) since 1956. The sedimentology and sequence stratigraphy of Paradox Shelf strata on the walls of the San Juan River gorge and in the subsurface Aneth Buildup are well documented. Less well documented are the stratigraphy and facies architecture of basinward extensions of upper Paradox sequences in the northern part of the Blanding Subbasin.

Available in PDF, EPUB and Kindle. Book excerpt: Five informal stratigraphic units can be recognized on well logs through the Marble Falls interval in the northern Fort Worth basin. Four of the units--an upper limestone, upper shale, lower limestone, and lower shale--are present in the eastern half of Wise County. These units interfinger to the west in Jack County with a heterolithic unit comprised of siltstones, mudstones and claystones. Facies recognized in core through the heterolithic unit and log curve shapes in the limestones and shales reveal shallowing-upward sequences formed as the basin filled. The basin fill contains authochthonous carbonate sediment produced in shallow epeiric seas and siliciciclastic (and perhaps carbonate) debris eroded off rising positive structures such as the Bend arch, Red River arch, Muenster arch, and the Ouachita thrust belt during the Ouachita orogeny. Revised correlations based on additional well control suggest the Comyn Limestone and the Forestburg limestone are the same lithostratigraphic unit.

This book was released on 2017-06 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our study documents the shelf, shelf-edge, slope, and basin-floor depositional facies characteristics, stratigraphic variations, and sedimentation trends of the Missourian Canyon Group and Virgilian-Wolfcampian Cisco Group across the southern Eastern Shelf and the adjacent Midland Basin. The Canyon Group (base Palo Pinto Limestone to top Home Creek Limestone) consists of an aggradational carbonate bank succession having locally prominent reef facies. Similar reef facies continued to accumulate during early Cisco sedimentation. The bank/reef interval, largely equivalent in age to the Horseshoe Atoll complex, is as much as 1,540 ft (469 m) thick in northeastern Coke County and forms an irregular, but distinct, shelf margin throughout the eastern part of the study area. Reef buildups are generally aligned at the margin but also occur as local pinnacles in the platform interior. Canyon basin-floor facies are equivalent to the lower part of the Cline shale ("Wolfcamp D") and consist primarily of dark, organic-rich (>2 percent organics) mudrocks. The overlying Cisco section comprises a series of 13 mudrock, limestone, and sandstone cycles (top Home Creek Limestone to top Coleman Junction Limestone), correlated from outcrop, that collectively form a progradational succession extending from the eastern edge (Bunger Limestone) to the central part of the study area (Coleman Junction Limestone). The top of the Home Creek Limestone coincides with a regional downlap surface for the progradational Virgilian lower Cisco shelf strata. Progressive upward decrease in height of shelf-margin clinoforms indicates that accommodation had markedly decreased during deposition of the upper Cisco Group. The Pennsylvanian-Permian (Virgilian-Wolfcampian) boundary is at the top of the Cline shale in the basin and slope provinces and just above the Crystal Falls Limestone in the shelf area. The thickness of the Wolfcampian section is regionally consistent at the shelf (~700 to 850 ft [~213 to 259 m]), expands markedly basinward to as much as 3,500 ft (1,067 m) into a regional depocenter of high accommodation and high sediment influx associated with slope sedimentation, and then thins into the basin proper (to
