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.1 Definition 1.1 Definition Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles Siltstone can be defined as a fine …Shale is a fine-grained sedimentary rock that forms from the compaction of silt and clay-size mineral particles that we commonly call "mud." This composition places shale in a category of sedimentary rocks known as " mudstones ." Shale is distinguished from other mudstones because it is fissile and laminated. This is because PC1 can separate the organic shale from the other lithofacies (see Fig. 5.6(a) and (c)). PC3 is the main discriminator for separating siltstone/sandstone from silty dolostone and dolostone (see Fig. 5.6(a) and (d)). Organic shale was well classified even though GR was not used to separate it from the other lithofacies.

When we have to compare Siltstone vs Oil shale, the texture, color and appearance plays an important role in determining the type of rock.

The stones make up between 50-95% of the formation of the area. In the United States, you can find many of these argillaceous rocks where water flows. This means within river banks, lakes, and offshore beaches. Wrapping Up. Argillaceous rocks break down into five groups. This includes argillite, claystone, shale, siltstone, and mudstone.Mudstone - hardened mud; a mix of silt and clay sized particles. The difference between mudstone and shale is that mudstones break into blocky pieces whereas shales break into thin chips with roughly parallel tops and bottoms. The terms shale and claystone are sometimes used interchangeably. Sedimentary rock Shale Composition Clay minerals and quartz Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al 2 Si 2 O 5 ( OH) 4) and tiny fragments ( silt -sized particles) of other minerals, especially quartz and calcite.

A siltstone is a lithified, nonfissile mudrock. In order for a rock to be named a siltstone, it must contain over 50% silt-sized material. Silt is any particle smaller than sand, 1/16 of a millimeter, and larger than clay, 1/256 of millimeter.
