Silt is detritus (fragments of weathered and eroded rock) with properties intermediate between sand and clay. A more precise definition of silt used by geologists is that it is detrital particles with sizes between 1/256 and 1/16 mm (about 4 to 63 microns). This corresponds to particles between 8 and 4 phi units on the Krumbein phi scale. Other geologists define silt as detrital particles between 2 and 63 microns or 9 to 4 phi units. A third definition is that silt is fine-grained detrital material co… WebJul 31, 2011 · According to unified soil classification system, if particle sizes of soil is less than 0.075mm, they may either be silt or clay. Both clay and silt fall under the category of fine grained soil. Clay A particular soil is classified as clay when it contains clay minerals. Clays are plastic and cohesive.
