Particle Shape Classification

As part of our strategic research we have developed classification systems and comparitor charts for various aspects of particle shape. Full details have been published in the following journal article:

 

Blott, S.J. and Pye, K. (2008) Particle shape: a review and new methods of characterization and classification. Sedimentology 55, 31-63. (view abstract)

 

 

The PDF documents below provide a number of visual comparators and graphical plots for use in analysing and displaying particle shape data:

 

• Visual comparators of particle elongation and flatness, roundness, circularity, sphericity and irregularity (PDF document, 1.1 MB).
• Classification of particle form in terms of elongation (I/L) and flatness (S/I) (PDF document, 1.1 MB).
• Blank triangular diagram, modified from Sneed and Folk, for plotting measurements of elongation (I/L) and flatness (S/I) (PDF document, 360 KB)
• Blank Zingg diagram, used for plotting measurements of particle elongation (I/L) and flatness (S/I) (PDF document, 360 KB)
