Detecting Radioactive Anomalies

The low penetrating power of alpha and beta particles make them unlikely to be detected during field surveys. Instead, most radiometric surveys concentrate on detecting gamma rays. The low attenuation rate of gamma rays passing through air make both ground … Continue reading

Detecting Density Anomalies

Gravity field surveying is a passive technique to detect gravity anomalies. Gravity is a global field that always points vertically down, with anomalies caused by very small variations in density of the underlying materials. A gravity base station measures the … Continue reading

Characterizing Density

Measuring density is a simple method of measuring the mass, measuring the volume, then calculating the density as mass divided by volume. Dry density, wet density, and grain density can all have geotechnical utility. All three are calculated by dividing … Continue reading

Density of Geological Materials

The density of a rock is closely tied to its mineralogy. Sedimentary rocks have a lower density than igneous rocks, with most sandstones having a density close to the density of quartz (ρ = 2.65 g/cm3), suggesting that they are … Continue reading

Density

Density (ρ) is the mass (m) of a material divided by its volume (V), given in units of mass per unit volume (kg/m3): ρ = m/V The density of a material is a function of the density of the individual … Continue reading
