Claystone sedimentary rock.

When the sediments harden, the layers are preserved. Sedimentary rocks formed by the crystallization of chemical precipitates are called chemical sedimentary rocks. As discussed in the “Earth’s Minerals” chapter, dissolved ions in fluids precipitate out of the fluid and settle out, just like the halite in figure 5.5.3 Clastic Sedimentary Rocks. A is a fragment of rock or mineral, ranging in size from less than a micron [1] (too small to see) to as big as an apartment block. Various types of clasts are shown in Figure 5.2.1 and in Practice Exercise 5.2. The smaller ones tend to be composed of a single mineral crystal, and the larger ones are typically ...Tendency to chemical cement. Ash: unconsolidated fragments under. 4 mm. Tuff: consolidated ash. Volcanic Breccia: angular fragments over 4 mm. Agglomerate: large proportion (>25%) of bombs. These rocks are classified on the proportions of vitric, crystal (mineral), or lithic material they contain, for example, "vitric lithic ash," or "crystal ...3) Shale: Fine-grained clastic sedimentary rock, silt and clay sized grains. Sediment deposited in lake bottoms, river deltas, floodplains, and on deep ocean floor. Fissile=Splits into thin layers. 4) Siltstone: Slightly coarser-grained than shales, non-fissile. 5) Claystone: Predominantly clay-sized grains, non-fissle

If it shows evidence of bedding or fine laminations, it is shale; otherwise it is mudstone.Part B Identifying & Interpreting Sedimentary Rocks. Sedimentary rocks can form from loose sediment of various sizes derived from preexisting rock (like mud, sand, and gravel), from mineral crystals (like silica or calcite) that evaporate or precipitate from water, or from the accumulation of organic material.

How Clastic Sedimentary Rocks are Formed: Pre‑existing rock undergoes chemical and mechanical weathering by roots, acid rainwater, gravity, wind, and water. The broken particles are carried through water or air until they settle out in a lower area when the current wasn’t fast enough to carry the particles.
