Figure F260. Cross-plot of bulk density determined by pycnometer and density estimated using calipers to define the wet volume of the rock cubes. Important sources of error include pycnometer problems and cubes with damaged edges or nonparallel faces. Despite the coarseness of the caliper measurement, the error in density is ~0.018 ± 0.001 g/cm3. In case of a complete pycnometer breakdown, it is practical to use method D for igneous rocks to determine moisture and density properties (see text).
