Despite advances in fractal geometry and multivariate statistics, most peer-reviewed journals still expect Folk and Ward statistics for sediment descriptions. Gradistat v 91 hot calculates these exactly as they were defined in 1957. Later "improved" software sometimes tinkered with the algorithms, breaking backward compatibility. V 9.1 is the canonical reference.
GRADISTAT v. 9.1 is a comprehensive grain size distribution and statistics package developed by Dr. Simon Blott (Kenneth Pye Associates Ltd). It is designed for the rapid analysis of unconsolidated sediments using data from standard measuring techniques such as sieving , laser granulometry , or X-ray sedigraph .
