Use this geological calculation for a transparent first-pass interpretation of measured rock, soil, fluid, well, stratigraphic, isotopic, geophysical, or seismic data under an explicitly selected model.

Rock

Rock type (supported list).

Look up the typical dry bulk density range in g/cm3 for a common rock type. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

High density

Upper end of the typical density range in g/cm3.

Low density

Lower end of the typical density range in g/cm3.

Mid density

Arithmetic midpoint of the typical density range in g/cm3.

• Geotechnical correlations and idealized failure models depend on stratigraphy, sampling disturbance, drainage, stress history, groundwater, density, anisotropy, scale, construction sequence, and laboratory or field method. Site-specific design requires investigation and code factors.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Compare independent measurements and models, retain units and analytical metadata, propagate uncertainty, and validate interpretations against logs, cores, maps, laboratory data, or field observations.

• Mineral Density Lookup

  Look up the typical room-temperature grain density in g/cm3 for a common rock-forming or ore mineral.

• Mineral Luster Lookup

  Look up the typical luster (quality of surface light reflection) of a common mineral.

• Mineral Cleavage Lookup

  Look up the number of cleavage directions and their quality/geometry for a common mineral.
