Partially weathered parent material is found in the C horizon of a soil profile.
The A horizon in soil is typically made up of mineral and organic material. In some instances the A horizon is only 2 to 3 inches deep, although it can be much deeper if the land has been plowed.
The A horizon, the uppermost layer in the soil profile, often is called the surface soil. It is the part of the soil in which life is most abundant in such forms as plant roots, bacteria, fungi, and small animals. It is the part in which organic matter is most abundant. The B horizon lies immediately beneath the A horizon and often is called the subsoil. Lying between the A and C horizons, it utilizes the properties of both. Living organisms are fewer than in the A horizon but more abundant than in the C horizon. THE C horizon is the deepest of the three major horizons. It consists of the loose and partly decayed rock beneath the A and B horizons. The rock material in the C horizon is of the same kind which now forms the bulk of the soil above it.
The middle mantle is made up of silicate rocks that are rich in iron and magnesium relative to the overlying crust.

The C horizon is based on bedrock. No soil is present that means that it is a layer of no penetration and usually consists of solid rock foundation.

Peat, which usually contains dead mosses and other plant material.
Primordial means it is the earlier form of its kind or dates from the start of a planet or universe. Primordial material is sometimes found on meteorites that fall to Earth.
