Grain Size Chart

Grain Size Chart - A scale of grade and class terms for clastic sediments. Clastic sediments form a wide range of rocks, from mudstone to conglomerate, and soil depending on their grain size. The chart shows the different size fractions from silt (63 µm) through to large cobbles (128256 mm). Mean grain size of loose sediments is measured by size analysis using sieves. Several such scales have been devised for the purpose of standardizing terms and providing a basis for statistical analysis. Among other things, grain size represents the conditions under which the sediment was deposited. Two important parameters for sediment transport are the median particle diameter d50 d 50 and the grading, for example, d90/d10 d 90 / d 10. Convenient sand grain sizing folder design. Classifies in accordance with the wentworth grade scale. Wentworth in a 1922 article in the journal of geology:
