This chapter aims to present a summary on the main physical and geomechanical properties of evaporitic rocks (evaporites), that is, sedimentary rocks of chemical origin composed mainly of chlorides, carbonates and sulfates such as halite, gypsum, anhydrite,...
The impact of water on the mechanical strength and physical properties of gypsum rock is particularly relevant to underground excavation ... Measured values of porosity range between 0.034 and 0.098, solid density ranges between 2.33 and 2.43 g/cm 3 and bulk density is between 2.15 and 2.27 g/cm 3.
Carbonates usually consist of calcite and dolomite, although siderite may be present. Gypsum and anhydrite are the most common sulfates, with pyrite the typical sulfide. ... This is a function of coupling between P- and S-wave through the shear modulus and bulk density. In contrast, if we plot bulk and ... where K d is the dry rock bulk …
and on the figure. Halite and anhydrite have markedly low and high bulk densities, respectively, while the very high neutron porosity of gypsum is caused by hydrogen in its water of crystallization.
The resulting value for bulk density is around 1.05 g/cm 3 and is typical for gypsum-based materials (usually greater than 0.8 g/cm 3 [24] ). All of the composites analyzed exhibited good...

Anhydrous gypsum (calcium sulfate) has a density of approximately 2.96 grams per cubic centimeter (g/cm³). Hydrated gypsum (CaSO4·2H2O) is less dense due to the presence of water molecules within its structure. ... Gypsum is often found in sedimentary rocks, particularly in layers or beds that contain evaporite minerals. …
If the rock has a lot of silt in it as well as sand, ... in the case of wind-blown or water-transported gypsum particles on playa surfaces in deserts. But once the deposit is lithified enough to be called a sandstone (and you should realize that the boundary between sand and ... bulk density color strength (tensile, compressive, shear) porosity ...
What is the bulk density of gypsum rock? Loose bulk density of natural gypsum is about 50 pcf. The bulk density of synthetic gypsums can vary widely from less than 40 pcf to over 70 pcf.
Explore a comprehensive table of density values for different rocks in both SI (kg/m³) and US customary (lb/ft³) units.

The bulk density or density log is related to the electron density of a formation and is the near-numerical equivalent of the formation's specific gravity (gm/cc); that is it is considered to measure variations in the average total density of the formation. ... A tool-measured value includes the solid rock matrix density and the density of ...
The dissolution of gypsum rocks induces a loss of solid material creating voids with different shapes and sizes that can lead to large underground collapse or subsidence in the case of an extremely vulnerable site exposed to "brutal ... Using the bulk density of the gypsum rock, which is written as a function of the grain density (2. ...

The ratio of CaO to SO 3 is a good chemical indicator of gypsum rock for evaluating its mechanical properties. A proper evaluation of engineering geological properties of gypsum rocks can be performed by studying the chemical composition in addition to their physical and mechanical properties.

Agricultural gypsum works as a soil amendment, conditioner and fertilizer to improve the soil, supplying calcium and plant available Sulfate Sulfur.
Primary gypsum deposits consist of rock gypsum (alabaster). Selenite, satin spar, and gypsite are secondary varieties of gypsum. Anhydrite may occur as either primary or secondary minerals in a deposit, depending on its geological history. ... and high density—characteristics that are desirable for construction and industrial plaster.

The Greek letter ρ (rho) symbolizes density. We usually give the density of a mineral in units of grams/cubic centimeter ... halite), and sulfates (e.g., gypsum). Silicates (including quartz and all the other common rock-forming silicates) and carbonates (e.g., calcite or dolomite) range from about 2.5 to 3.5. Oxides and sulfides may have ...
The bulk density of rocks depends on the mineral composition of the constituent rocks, the degree of pore development and their water content. ... and to those rocks, clays or shales, gypsum, rock salt, etc., in which fluids have difficulty in flowing, as non-permeable rocks. But this formulation is not strict, because on the one hand ...
