"The samples were collected from Folsom Lake next to Granite Bay, near Sacramento. The reservoir is way down(they open the tainter gates each year in preparation for new water from snow melt in the Sierras). One can walk along the shoreline filled with large granite boulders in the foothills of the Sierras. Interesting texture and fascinating geology." Gary Foster |

It is expressed as the ratio of the average radius of curvature of the edges or corners to the radius of curvature of the maximum inscribed sphere.The sphericity of a particle is: the ratio of the surface area of a sphere (with the same volume as the given particle) to the surface area of the particle. |
