A detail sedimentological analysis of the Sarki Formation (Early Jurassic) in Warte and Zarwan sections Imbricated Zone, northern Iraq has been conducted for first time. The both studied are consisting dolomite, dolomitic limestone recrystallized breccia. petrographic study 80 thin analyzed outcrops showed skeletal non-skeletal components. components including ostracods, bivalves echinoderms. W...

Determining the dissolution rates of carbonate rocks is vital to advancing our understanding cave, karst, and landscape processes. Furthermore, role important for global carbon budget climate change. A laboratory experiment was setup calculate two whole rock samples with different petrographic makeup (ooids brachiopods). The were also explored under a scanning electron microscope evaluate textu...

Distinct parts of limestones within the upper Paleozoic Auernig Group of the Carnic Alps, Austria and Italy, are characteristic of cool-water carbonates. The Carnic Alps were between 5 N and 10 S paleolatitude during the late Carboniferous, a position confirmed by dasyclad algae and fossil plants. The floral association, occurrence of coal seams, and absence of evaporites indicate a humid tropi...

Abstract Models that introduce rolling resistance at the contact are widely employed in simulations using discrete element method (DEM) to indirectly represent particle shape effects. This approach offers substantial computational benefits price of increased calibration complexity. work proposes a simplify resistance. The key is an empirical relation between parameter (rolling friction) and 3D ...

Several studies have been carried out by various authors on limemud that occurs in the western Indian offshore which is compositionally CaCO3, amorphous, homogeneous, creamy white, soft and non sticky sediments mainly consisting of ooids. The chief mineral constituent aragonite. age, occurrence, formation estimation resource are compiled from published literatures briefly presented.  Bench...
