Porosity in Oolitic Limestones
In oolitic limestones the individual grains are microporous, and the microporosity consists of irregular equant pores 1-3 (mu)m in size which are located between the rhombic to anhedral carbonate crystals which make up the ooid cortex. These equant micropores are locally constricted to plates or …

Cementation and dolomitization of Mississippian limestones, Kentucky and Virginia
… in much of the remaining void space in the limestones. During uplift of the sequence late calcite cements with decreasing Fe contents were precipitated from increasingly oxidizing fluids that penetrated the section through fractures and remaining pore spaces.

Poroelastic properties of carbonates: a case study on Indiana limestones
This thesis studies the poroelasticity of carbonate rocks and investigates the dependence of various physical properties on confining pressure and pore pressure. These physical properties include porosity, permeability, static strain, ultrasonic P- and S-wave velocities. In a process, I estimate …

Ordivician limestones in the vicinity of Hoges Store, Giles County, Virginia
… certain portions of the Five Oaks and Elway limestones containing more than 97 per cent calcium carbonate crop out near the event of the Thessalia anticline and John's Creek syncline and underlie an extensive area where dips probably are less than 20 degrees. Locally, part of the Benbolt, …

Isotopic - Textural - Chemical Studies of Mid-Cretaceous Limestones: Implications for Carbonate Diagenesis and Paleooceanography
… and nonskeletal components from Mid-Cretaceous limestones have been investigated using coordinated textural, isotopic, and chemical methods to delineate their diagenetic histories and to provide information on the temperatures and salinity of contemporaneous seawater. The degree of alteration of …

Sequence stratigraphy and structure of the tertiary limestones in the Gulf of Papua,Papua New Guinea
… and depositional architecture of the limestones, and the morphology of the basin at the time of deposition. The results of the study were integrated with published geological and tectonic models for the Papuan Basin to develop a consistent and coherent model for the depositional …

Sedimentology of the Mid-Visean limestones of the southern part of the Askrigg Block, North Yorkshire
The earliest Carboniferous deposits, resting with profound unconformity on Lower Palaeozoic rocks, have been mapped across their entire outcrop area on the Askrigg Block. The sediments, comprising approximately half of the thickness of the Dinantian Great Scar Group, have been subdivided into four …

Petrography, Sedimentology, Diagenesis, and Reservoir Characteristics of Some Pennsylvanian Phylloid Algal Limestones: Kansas and Utah, u.s.a. (United States)
The Paola and Raytown limestone members of the Iola Formation (Missourian) of southeastern Kansas have been systematically analyzed with 1200 thin sections. These rocks contain a typical Pennsylvanian biotic assemblage of phylloid algae, bryozoans, encrusting foraminifers, fusulinids, Composita, …

Determination of calcium and phosphorus digestibility and relative calcium bioavailability in limestone sources from different countries and interactions with phytase
Two experiments were conducted to evaluate 18 limestones varying in country origin and calcium (Ca) solubility for Ca digestibility and utilization in broiler chickens. The 18 commercial limestones came from several different countries (Asia, United States, South Africa, and Europe). Sources varied …
