2016-11-15 In situ density can be estimated by knowing the properties and relative proportions of each constituent. Traditional ash-based methods to estimate density are imprecise because ash is a combustion residue that does not contain all of the original mineral matter, as volatile components of the minerals are lost upon combustion.

2021-11-18 The relative density of natural or compacted soil can be determined by obtaining the minimum and maximum density of soil in the laboratory and the in-situ density of soil in the field. The test is applicable for freely draining cohesionless soils only. The minimum density in the loosest state is obtained by pouring the soil sample into the mold ...

2008-6-16 Density plays an important role in coal resource estimation and reconciliation, as well as in defining coal quality. Current practice employs direct density measurements on widely spaced core samples, rather than utilising abundant geophysical logging data. This is mostly due to the perception that the precision and accuracy of density estimation from geophysical logs is unsatisfactory. This ...

Grain density describes the density of solid or mineral grains of the rock.. Grain density can give an indication of the mineralogy of the rock: Dolomite, ρ = 2.8–3.1 g/cm 3 Shales, ρ = 2.65–2.8 g/cm 3 Shales are composed of several minerals that have different densities in different relative amounts.
