WebSorting. Sorting is the variability in grain size in a clastic sedimentary rock. This parameter measures how well a sediment has been ‘sorted’ by the process that transported it. A sediment can be: – very well sorted: nearly all grains have the same size. – well sorted: most grains fall in a single grain size class with few outliers. WebAug 28, 2024 · It was originally developed in soil science, with concepts of plasmic fabric and morphological features and structures dating from the early 1960s 1. ... Increases in grain size allow for more perturbations. As a result, a poorly sorted, coarse grained till will be more micromorphologically inhomogeneous than a finer-grained till.

WebPorosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%. Strictly speaking, some tests measure the "accessible void", the total amount of void space accessible from the surface (cf. closed-cell foam).
