Clay mineral particles are generally crystalline in form and are of colloidal size, that is, they are less than 0.002 mm. These minerals give soil the prop-erties of cohesion and plasticity, which are the distinctive characteristics of clay. The nature of the clay mineral produced in any given situation is depen-dent on both the parent rock and ...

The particles of these sedimentary rocks can be found with different configurations in different places within a reservoir rock which are known as clay distribution types. As one can infer from Fig. 1, such clay particle can be originated from reworked and redeposited shale fragments or from diagenetic clay minerals.

Chapter 3 Information on Texture : (Rock description)
Texture plays a very important part in sedimentary rocks, because the petrophysical properties of a rock, hence its porosity and permeability, depend essentially on texture. Regardless of the type of texture, sedimentary rocks are marked by the textural characteristics of three components: grains or particles and crystals; matrix that ...

Overview of Sedimentary Rocks – Introductory Physical Geology
If the rock is largely made from pieces of rock (called clasts) that have been mechanically weathered, the rocks are referred to as Detrital or Clastic Sedimentary Rocks. These rocks are composed of broken pieces of other rocks. In this case, the mineralogy of the clasts is not important, but we need to note the properties of the sediment itself.
