Is shale clastic.
The "interior" shale. The shale core is a heterolithic mix of carbonates and clastic material that is cross-laminated and flaser-bedded. The log curves show a shale character and suggest other "non-shale" components in this unit, when compared with the log responses of the "lower shale". visual examination of the curves.

Shale is well-sorted with silt, mud, or clay-sized clasts that The shale content is important in reservoir quality evaluation. There are good relations between effective porosity, permeability, and shale content in clastic rocks. One of the main objectives of the velocity-deviation log is that it could indicate permeability qualitatively. The velocity-deviation logs could be calculated from density and neutron porosity logs in carbonate rocks. The ...Siltstone.

Shale is the most abundant of the sedimentary rocks, accounting for roughly 70 percent of this rock type in the crust of the Earth. Shales are often found with layers of sandstone or allen and roth cordless cellular shade Cemented, non-organic sediments become clastic rocks. If organic material is included, they are bioclastic rocks. Fluids fill in the spaces between the loose particles of sediment and crystallize to create a rock by cementation. Figure 13. This cliff is made of sandstone. Sands were deposited and then lithified.Rocks that are often misidentified as shale: Slate – A low-grade metamorphic rock often formed from shale. Is often hard, and rings when struck. Siltstone – A clastic sedimentary rock similar to shale but with slightly larger, visible grains. Mudstone – Very similar to shale, but with no visible laminations (massive).
