Limestone is a sedimentary rock consisting of more than 50% calcium carbonate ( calcite - CaCO 3). Some limestones form from the cementation of sand and / or mud by calcite ( clastic limestone), and these often have the appearance of sandstone or mudstone.

Thin-section. The ooids look brown. They are made up of calcite grains much smaller than the thickness of the slide (which is 30μm). These small grains refract, diffract and reflect light travelling through the slide producing the brown appearance of the ooids. Most of the ooids were formed around a central nucleus (usually an angular quartz ...

Le Guen et al. studied the oolitic limestone of Lavoux and concluded that the PSC accelerating effect of high-p CO2 solutions was mainly due to the acidification of the injected solutions, resulting in a significant increase in solubility and reaction kinetics of calcite, and that all samples showed a positive correlation solution flow rate and ...

A new micromechanical approach to analytical modeling of oolitic limestone is proposed. Limestone is modeled as a multiphase composite consisting of sparry calcite matrix, spherical oolitic inhomogeneities, oblate spheroidal pores of aspect ratio 0.2, and concave pores in the shape of superspheres (the concavity factor is the key parameter affecting overall properties).
