Texture refers to the physical makeup of rock—namely, the size, shape, and arrangement (packing and orientation) of the discrete grains or particles of a sedimentary rock. Two main natural textural groupings exist for sedimentary rocks: clastic (or fragmental) and nonclastic (essentially crystalline).– A well sorted and mature detrital (clastic) sedimentary rock made up of sand sized quartz grains (1/16 – 2mm in size).

Conglomerate is a clastic sedimentary rock made up of rounded clasts that are greater than two millimeters in diameter. The spaces between the clasts are generally filled with sand- and clay-size particles. The rock is bound together by a cement that is usually composed of calcite or quartz.

n decreases slightly when grain size increases from 0.5–1 mm to 1–3 mm, while it shows a positive change in n values for grain size of 3–5 mm. Changes in solution salinity significantly influence the resistivity and saturation exponent of limestone grains, with higher solution salinity resulting in lower resistivity and higher saturation exponent. …The degree of polish that can be achieved depends on the grain size and density of the stone. As limestone is formed from sediment, stone types that have variability in the bedding sediment or large fossil fragments are more likely to display changes in appearance and strength when slabbed in different orientations.Sandstones. Sandstones are siliciclastic sedimentary rocks that consist mainly of sand-size grains (clast diameters from 2 to 1 / 16 millimetre) either bonded together by interstitial chemical cement or lithified into a cohesive rock by the compaction of the sand-size framework component together with any interstitial primary (detrital) and secondary (authigenic) finer-grained matrix component. Grain size is the average diameter of clasts (particles) of clastic sediments and rocks. Grain size is the primary parameter in sedimentary geology to divide clastic rocks and sediments in different classes for classification purposes.
