Shale texture has been quantitatively deGray shale, carbonaceous shale, and sandstone Jun 24, 2015 · The way shaliness affects a log reading depends on the amount of shale and its physical properties. It may also depend on the way the shale is distributed in the formation. Shaly material can be distributed in the formation in three ways: Shale can exist in the form of laminae between which are layers of sand. Physical properties of rocks are used to identify the type of rocks and to discover more about them. There are various physical properties of Shale like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it. The physical properties of Shale rock are vital in determining its Shale Texture and Shale Uses.
