Porosity and Bulk Density of Sedimentary Rocks

POROSITY AND BULK DENSITY OF SEDIMENTARY ROCKS By G. EDWARD MANGER ABSTRACT More than 900 items of porosity and bulk density data for sedimentary rocks have been tabulated. Most of the data are from the more accessible American, British, German, and Swiss literature. The number of porosity determinations per item ranges from 1 to 2,109.

What are some special properties of calcite? - Quora

What is Calcite? Calcite is a rock-forming mineral with a chemical formula of CaCO3. It is extremely common and found throughout the world in sedimentary, metamorphic, and igneous rocks. Some geologists consider it to be a "ubiquitous mineral" - one that is found everywhere. Calcite is the principal constituent of limestone and marble.

POROSITY LOGGING - Kansas Geological Survey

POROSITY LOGGING The porosity of a zone can be estimated either from a single "porosity log" (sonic, density, neutron, or magnetic resonance log) or a combination of porosity logs, in order to correct for variable lithology effects in complex reservoirs. In the carbonates, mineral mixtures are primarily drawn from calcite, dolomite, and

Aragonite (density 2.95) is denser than calcite (density 2.71) and should thus be a higher pressure form of CaCOr than calcite. Natural aragonite on heating converts to calcite, the conversion being very rapid at temperatures above 400' C. This would indicate that calcite is a higher temperature form than

Understanding porosity and density - UW-Ex

Density is defined as the mass per volume. In rocks, it is a function of the densities of the individual grains, the porosity, and the fluid filling the pores. There are three types of density in rocks: dry density, wet density, and grain density. The data table lists the dry, wet, and grain densities of the samples.
