Bouma (1962, pp. 48–51) describes an “ideal” graded-bed sequence, in rocks of probable turbidity current origin, that consists of five distinct divisions. A final example is coquina, which is a chemical sedimentary rock also made of calcite, in the form of slightly broken pieces of clam shells and snail shells. The analysis of structures is often accomplished by plotting the orientations of various features onto stereonets.

If a sedimentary rock does not look like gravel, sand, silt or mud and seems to be made of a single mineral it is probably a chemical sedimentary rock.

Primary example: coal what the rock is made out of. depends on how long it underwent weathering/transportation before deposition. reduces pore space. Happens when sediments are deeply buried, placing them under pressure because of the weight of overlying layers. This squashes the grains together more tightly. fills in pore space , e.g. Microstructure of Fine-Grained Sediments: From Mud to Shale (Frontiers in Sedimentary Geology) download online Microstructure of Fine-Grained Sediments: From Mud to Shale (Frontiers in Sedimentary Geology). Look at the chart on page 7 in your reference tables to find the specific sizes.

In older metamorphic rocks oftentimes several successive episodes of metamorphism can be determined with modern methods of investigation (age determination on minerals of different stability, different isotopic systems). Thus, deformation of the earth's crust occurred repeatedly during geologic history. This is evidence for continued tectonic movements and readjustments of the earth's crust throughout documented geologic history ref.: Engineering Properties of Soils and Their Measurement click Engineering Properties of Soils and Their Measurement. Local geothermal and pressure gradients interact with the materials in the local rock column to establish one or more brittle-ductile transitions (BDTs) within each distinct column in the crust. Rocks above a BDT fracture when applied stresses and resultant strains exceed certain limits, while rocks below deform in a plastic manner with little if any fracturing download Sea-Ice and Iceberg Sedimentation in the Ocean: Recent and Past epub.

It is not common to find a single small rock that has a complete joint surface, and with such a remarkable display of plumose features. This red siltstone was subjected to tectonic stresses in ways that caused it to be pulled apart, i.e., lengthened.

Water is by far the most common pore-space fluid found in sedimentary deposits. Water rich in dissolved iron oxides, calcite (calcium carbonate) or silica (silicon dioxide) can deposit these minerals as cement between sediment grains.

Geologic maps, which are useful guides for collecting, are also excellent identification aids. They show the distribution and extent of particular rock types or groups of rock types. Depending on size and scale, the maps may cover large or small areas. Most have brief descriptions of the rock types. Some are issued as separate publications; others are included in books.
