WebMar 14, 2024 · The bulk density is less than the grain density of the constituent mineral (or mineral assemblage), depending on the porosity. For example, sandstone (characteristically quartzose) has a typical dry bulk density of 2.0–2.6 g/cm 3 , with a porosity that can vary from low to more than 30 percent. WebThe "density porosity" of the granite has no immediate meaning, scaled as it is to a limestone-porosity system. However, a simple backcalculation of the bulk density measurement gives an estimated density of about 2.6 gm/cc. A more extensive discussion of log properties will be made in the section on Igneous and Metamorphic Rocks.
