International Space Station 180mm Photograph Image credit: Image Science and Analysis Laboratory, NASA Johnson Space Center | GRAIN SHAPE CHARACTERISTICS(PREPARED BY GAMMA ZETA CHAPTER , SIGMA GAMMA EPSILON, KENT STATE UNIVERSITY - AGI CHART))Roundness is the degree of smoothing due to abrasion of sedimentary particles. 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. |

The most common geologic characteristic at The Glades is the interaction between Granite and Basalt. In all cases the granite formed first, and then the basalt created dikes in the Granite. In some cases the dikes have feldspar or quartz crystals in them. (Note: Toes are included for scale) |
Then there is this unusual mixture of Granite and Basalt! |

This one outcrop had an unusual alignment of lines that I assume are glacial striations. |
