What is the porosity of sandstone and mudstone? How much difference? Is it possible to distinguish lithology from the difference in porosity of sandstone and mudstone?
With the increase of the depth of mudstone and sandstone pore porosity decreased rapidly, decreased relatively slowly, when thousands of meters, due to the influence of sandstone pore cementation, the porosity can be maintained at around 10% (all different), and mudstones are generally only 1% left and right, therefore, in the condition of deep burial porosity is one of the reference parameters, distinguish lithology.
It depends on the depth of the underground. The porosity of mudstone is very high, which can be as high as 60%-70%, and the porosity of sandstone should be about 30%-40% during the deposition.
