This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Indian Subcontinent contained a wide shallow marine continental shelf during most of the Paleocene and Eocene epochs before its collision with Eurasia. The Indus Basin formed the Pakistani portion of the subcontinent where carbonate deposition was prominent. The Lockhart Limestone is among the carbonate-dominated lithologic units developed in the Indus Basin. The latter has been divided into sub-basins due to the tectonic disturbance related to the Indian-Eurasian collision. In the northern part of the Indus Basin, the sub-basins Kohat, Potwar and Hazara constitute the upper Indus Basin. The study area is located in the Potwar and Hazara sub-basins. The Lockhart Limestone overlies early Paleocene Hangu Formation and is overlain by latest Paleocene to early Eocene Patala Formation, both with confirmable contacts. The Lockhart Limestone is 50 meters thick in the Potwar Sub-basin and 85 meters thick in the Hazara Sub-basin. Seven sections, three from Hazara area and four from Potwar area were studied for lithofacies characteristics, depositional environment, biostratigraphy, cyclicity and sequence stratigraphy of the Lockhart Limestone. The different lithofacies occur in different stratigraphic horizons that constitute the formation; they include fossiliferous calcareous shale (Lf1), planktonic-bearing mudstone (Lf2), Discocyclina-Ranikothalia wackestone (Lf3), mixed benthic foraminiferal wackestone-packstone (Lf4), Lockhartia-Miscellanea wackestone-packstone (Lf5) algal-foraminiferal wackestone-packstone (Lf6) and milliolid-bearing mudstone (Lf7). These lithofacies accumulated in subtidal conditions as suggested by their lithologic properties, fossil content and absence of intertidal and supratidal signatures. However, the vertical arrangement of these facies make cyclicity, as each cycle contains different lithofacies that change from deeper to shallower facies ii (A, B, C& D). The depositional setting is a ramp-type platform in which Lf1, Lf2 and Lf3 represent the deepest facies (outer ramp) followed by Lf3, Lf4 and Lf5 accumulated in the middle ramp, and finally by Lf6 and Lf7 of the inner ramp setting. Some of the larger benthic foraminifera are good index fossils that are useful for biostratigraphic age determination. These index fossils include Lockhartia conditi, L. haimei, Miscellanea miscella, Ranikothalia sindensis, and Discocyclina sp, which indicate Thanatian SBZ 3 & 4 (58 -56.5 Ma) age for the formation. Nine meter-scale shallowing-upward (Milankovitch) cycles were recognized from the Lockhart Limestone. In conjunction with the underline Hangu Formation and overlying Patala Formation, two transgressiveregressive cycles (TR-1 and TR-2) divide the HLP cycle in two parts. The Lockhart Limestone with the upper part of underlying Hangu Formation and the lower to middle part of overlying Patala Formation were deposited in a single 3rd order cycle (the HLP cycle).

This book was released on 2013 with total page 518 pages. Available in PDF, EPUB and Kindle. 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.

Book excerpt: Master's Thesis from the year 2013 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, grade: 1, University of Nigeria (University of Nigeria, Nsukka - Department of Geology, Physical Sciences), course: Petroleum Geology - Earth Science / Geosciences, language: English, abstract: Analytical studies on lithofacies delineation, environment of deposition, stratigraphic framework, structural configuration, hydrocarbon type and distribution in the Middle to Late Miocene sequence of Niger Delta basin, were carried out in the Eastern part of the Coastal Swamp depo-belt using information obtained from 3D regional seismic volume, wireline logs, paleobathymetric and biofacies data across nine fields. This involved analyses and interpretations, aimed at establishing; the main lithofacies units, system tracts, depositional sequences, reservoirs, seals and also the influence of structures on stratigraphy and hydrocarbon trends across several oil and gas producing fields. Facies analyses reveal the occurrence of four lithofacies units. Well log sequence stratigraphic analysis and correlation across these fields indicates that ten major stratigraphic bounding surfaces, five each of sequence boundaries (SB) with ages ranging from 13.1Ma through 8.5Ma and maximum flooding surfaces (MFS) with ages between 12.8Ma and 7.4Ma respectively, were identified and correlated. Four depositional sequences were delineated and stratigraphic flattening at various ages (MFSs) indicates that there is a shift of the depo-center from north to south. Stacking patterns were delineated and interpreted as lowstand systems tract (LST), highstand systems tract (HST) and trangressive systems tract (TST) using their bounding surfaces. The alternation of these systems tracts offers good reservoir sands and source/seal shales for hydrocarbon accumulation. Paleobathymetric maps show generally, that sediments were deposited within neritic through bathyal environments at different times,

Available in PDF, EPUB and Kindle. Book excerpt: Lithostratigraphic Analysis of Sedimentary Basins deals with the concepts and methodology of lithostratigraphic analysis used to elucidate various aspects of the geological history of sedimentary layers within a basin. The principles of stratigraphy and sedimentation as well as the influence of tectonism are discussed, along with their relevance to a variety of methods employed in the analysis of sedimentary basins. Comprised of seven chapters, this book begins with a classification of sedimentary basins and an overview of the methods used in their analysis. Certain lithological features, including sedimentary structures, textures, and assemblages of features that are considered to be diagnostic or indicative of particular depositional environments, are discussed, together with their implications for interpretations of the geologic history of a sedimentary basin on the basis of both macrostratigraphic and microstratigraphic criteria. Other lithologic analyses that are mentioned relate to petrophysical properties such as porosity and permeability and to chemical properties such as trace element, organic, and hydrocarbon content. Methods employed in the examination of outcrops and rock samples are also considered. The final chapter describes the application of sedimentary basin analysis to exploration of oil and gas, coal, and minerals, together with potential storage reservoirs for natural gas. This monograph will be of interest to geophysicists, geologists, geophysicists, and engineers.
