Lab 1 Roundness and Sphericity

Lab 1 Roundness and Sphericity. In this lab you will determine the roundness and sphericity of a number of sedimentary particles and will investigate the relationship between these two properties of particles. Roundness Roundness refers to the sharpness of the corners and edges of a grain.

Presentation Transcript

  1. Lab 1 Roundness and Sphericity In this lab you will determine the roundness and sphericity of a number of sedimentary particles and will investigate the relationship between these two properties of particles.

  2. Roundness Roundness refers to the sharpness of the corners and edges of a grain. Well-rounded Angular Sub-rounded

  3. To determine the roundness of our grains we will estimate by a visual comparison to grains of known roundness.

  4. Sphericity Sphericity measures the degree to which a particle approaches a spherical shape. It will be determined for our grains by measuring the three linear dimensions (longest(L), Intermediate (I) & Shortest (S) diameters).

  5. Sphericity Measurements

  6. Review . . .

  7. Measurement = 1.28 How do you use the calipers?
