Natural and Experimentally-Simulated Stylolitic Porosity in Carbonate Rocks
The natural occurrence of stylolitic porosity was studied by the detailed petrographic analysis of Lower Permian Wolfcamp limestones. Based on the observed, natural vertical succession of the microfacies and on the petrographic study of thin sections, an ideal, shallowing-upward sequence was …

Thermoluminescence in Carbonate Rocks and its Application to Stratigraphic correlation and Geologic Age Determination
… of phosphoroscence and is common to most carbonate rocks. Although the phenomenon has been known since at least 1663, its use in geology was not investigated until 1948. </p><p>Thermoluminescence results from the release of energy stored as displaced electrons in the crystal lattice. …

Structural diagenesis of bed-parallel and bed-normal fractures, Cretaceous Crato Formation carbonate rocks, NE Brazil
… in well-layered regions of pre-salt source rocks assuming petroleum generation is significantly high or fluid overpressure occurred sufficiently early in the burial history of pre-salt source rocks. Bed-parallel fractures may serve as storage sites or assist in the lateral transport of …

Studying Redox Conditions of Devonian and Neoproterozoic Oceans Using I/ca Proxy From Bulk Carbonate Rocks
… the only species that can be incorporated into carbonate minerals. Therefore, I/Ca ratio from carbonate rocks can be used to constrain the redox condition in the water column over a range of time scale. This dissertation contains three chapters that utilizes I/Ca ratio from bulk carbonate rocks …

SILICON ISOTOPE AND PETROGRAPHIC INVESTIGATIONS OF SILICIFIED CARBONATE ROCKS: IMPLICATIONS FOR IMPROVED PARAGENETIC SEQUENCING AND PROXIES FOR PALEOZOIC OCEAN CHEMISTRY
… study uses silicon isotopic data from silicified carbonate rocks to investigate their paragenesis and discusses the implications of the data to the silicon isotopic budget and overall silicon cycle in pre-diatom oceans. Petrographic study of silicified coral fossils from the mid-Paleozoic Cutter …

The Lower Carboniferous (Chadian-Brigantian) geology of shallow marine carbonate rocks in the central and southeast Irish Midlands and the Wexford Outlier
"This is the first comprehensive study, consisting of integrated petrographical, paleontological and geochemical analyses on the post-Waulsortian strata in the central and southeast Irish Midlands. This study reveals that the style of sedimentation and early diagenesis substantially influenced the …

Depositional conditions, stratigraphic evolution, and allo- and autogenic controls of lower Permian non-marine carbonate rocks, Lucaogou low-order cycle, Bogda Mountains, NW china
… the depositional conditions of lacustrine carbonate deposits of the lower Permian Lucaogou low-order cycle in the greater Turpan-Junggar continental rift basin, NW China. The depositional environments of ten carbonate lithofacies in the Tarlong-Taodonggou half graben and the Zhaobishan …

Hydrologic and Geochemical Cycling within Karst Versus Non-Karst Basins within the Interior Low Plateau Province of South-Central Kentucky
… Mammoth Cave National Park. Twelve percent carbonate rocks underlie one basin, while the other consists of 48 percent carbonate rocks. The carbonate rock exposures within both basins exhibit karstification. The hydrologic and geochemical differences between these basins were compared to …

The Role of Water and Strain Rate in the Deformation of Limestone
… mechanical and petrophysical properties of host rocks. This study focuses on the role of fluids in weakening porous carbonate rocks. High solubility of calcite can cause chemically-induced weakening and lead to time-dependent deformation in carbonate rocks. To quantify the effect of …

Geology of Sub-Salt Carbonate Rocks in the Rozhkovsky Structure, Northern Precaspian Basin, Kazakhstan: Implications for the Formation of Carbonate Reservoir in a Relatively Closed Diagenetic System
Sub-salt carbonate successions in the Precaspian Basin host several world-famous oil/gas fields along the basin margin. The Early Carboniferous Sub-salt carbonate rocks are associated with the Rozhkovsky structure near the northern margin of the Precaspian Basin. These carbonate successions are …

Integrated geological and petrophysical investigation on carbonate rocks of the middle early to late early Canyon high frequency sequence in the Northern Platform area of the SACROC Unit
The SACROC unit is an isolated carbonate platform style of reservoir that typifies a peak icehouse system. Icehouse carbonate platforms are one of the least well understood and documented carbonate reservoir styles due to the reservoir heterogeneities they embody. The current study is an attempt to …

Geology of the Damascus area
Marine sedimentary rocks ranging in age from Early Cambrian(?) to Middle Ordovician, inclusive, crop out in the Damascus area. Approximately 13,000 feet of beds are exposed, comprising 14 formations. The stratigraphic succession is rather complete and is broken by a single recognizable hiatus which …

Multi-Proxy Records of Climate and Carbon Cycle Perturbations in the Paleozoic: Integrating Isotope Geochemistry and Sedimentology
Carbonate rocks are a valuable archive of past environmental conditions. To glean robust information from this archive, we must understand how carbonate sediments form, ensure our analytical techniques are optimized, and consider how inherently local deposition of sediments can communicate …

Carbonate Microfacies and Depositional Environments of the Kinkaid Formation (Upper Mississippian) of the Illinois Basin
The carbonate rocks of the Kinkaid Formation (Upper Mississippian) of the Illinois Basin were sampled at an average vertical interval of 17 centimeters from twelve stratigraphic sections in Southern Illinois and Western Kentucky, to determine their environments of deposition. Thin sections wer
