The soil matrix is the solid phase of soils, and comprise the solid particles that make up soils.Soil particles can be classified by their chemical composition as well as their size.
Parent material is the underlying geological material (generally bedrock or a superficial or drift deposit) in which soil horizons form. Soils typically inherit a great deal of structure and minerals from their parent material, and, as such, are often classified based upon their contents of consolidated or unconsolidated mineral material that has undergone some degree of physical or chemical ...
Marbut's Pedocal/Pedalfer boundary lies near the 98 meridian and 30 inches annual precipitation. (after Marbut, 1935) Pedalfer is composed of aluminum and iron oxides. It is a subdivision of the zonal soil order comprising a large group of soils in which sesquioxides increase relative to silica during soil formation.
Sandrail at Dumont Dunes CA 2011. A sandrail, also called a sand rail, rail, or sand car, is a lightweight off-road motor vehicle specifically built for traveling in sandy terrain. Synonymously referred to as dune buggies, a sandrail is a type of speciality vehicle. [1] They are popularly operated on actual sand dunes. Sandrails can be driven ...
The field equations of condensed matter physics are remarkably similar to those of high energy particle physics. As a result, much of the theory of particle physics applies to condensed matter physics as well; in particular, there are a selection of field excitations, called quasi-particles, that can be created and explored. These include:

For example, a land on a major Project is marked as glacier on contract drawings. It was so hard that it had to be detonated. The contractor claimed that the soil was cemented during excavation as it was formed due to the clay matrix as well as the gravel. The owner concluded that this was due to the weathering of the pebbles.
Deposition can also refer to the buildup of sediment from organically derived matter or chemical processes. For example, chalk is made up partly of the microscopic calcium carbonate skeletons of marine plankton , the deposition of which induced chemical processes ( diagenesis ) to deposit further calcium carbonate.
