Porosity of siltstone
WebJan 1, 2003 · The relationship between porosity and permeability of a fine-grained sediment is one of nature’s largest contrasts, one that covers 13 to 15 orders of magnitude. Determining the permeability of fine-grained sediments, that are virtually impermeable, is a difficult accomplishment and can only be achieved accurately by certain geotechnical … WebAnswer (1 of 4): Both are ‘porous’ in that they both contain pore space. But the spaces between the larger sand grains are bigger than the spaces between the smaller silt grains, so a sandstone typically will hold more water than a siltstone will. In addition, we are often interested in permeabi...

Silt accumulates in sedimentary basins … WebOct 29, 2024 · Silt accumulates in sedimentary basins throughout the world. It is a form of mudrock with a low clay mineral count and can be differentiated from shale by it's lack of fissility. Permeability and porosity is low. It is less common than sandstone and shale. Siltstone occurs in a wide range of colors.
