sandstone density

2019-12-24 · Sandstone is a classic sedimentary rock comprising an aggregate of sand­sized (0.06–2.0­mm) fragments of minerals, rocks or fossils held together by a mineral cement. Actually, sandstone forms  when sand  is   buried  under  successive  layers  of  sediment.  During  burial  the  sand  is compacted and a binding agent such as quartz, calcite or iron oxide is precipitated from ground water which moves through passageways between grains to create Sandstone.

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.
