It is called rock to a solid and hard stone. Geology defines rocks as cohesive solids that are formed by one or more minerals. The notion of mother , on the other hand, refers to a female who gave birth or the origin of something.
The idea of mother rock mentions that rock that defines the mineral matrix of a I usually . In other words, the mother rock is the kind of rock on which the soil rests. Through erosion and a weathering process, the mother rock allows the development of the inorganic sector of the land in question.
It is important to note that on this mother rock they accumulate layers of other rocks, fragments of materials, land , vegetation, etc. The different layers are called horizons .
The mother rock is the horizon composed of rocky material that did not undergo any physical or chemical change of importance. According to relationship that maintains the mother rock with the rest of the horizons, you can distinguish between native soil and allochthonous soil .
Above the mother rock are the subsoil , the precipitate zone , the vertical wash zone and the surface layer , in that order. This means that what we see from the ground, such as grass, branches or leaves, is the surface layer of the ground, the one that is furthest from the mother rock.
It is important to determine, in addition to all of the above, another series of interesting data about this mother rock:
-The science that is responsible for studying that and the soils in general is called Edaphology. This, more exactly, can determine what is the branch of science that proceeds to analyze in depth what is the composition and nature of the soil in terms of the relationship it maintains both with the environment and with existing plant species. In the eighteenth century is where the origin of this discipline.
- Fundamental soil factors such as fertility, morphology, physical properties, thickness or even physical-chemical properties will depend on the mother rock.
-Among the types of mother rocks that may exist are marl and limestone.
-The marls have the particularity of being sedimentary and are the result of the union between what is clay, which arises from what is the decomposition of feldspars of aluminum ores, and what is limestone.
-The limestones, on the other hand and as its name suggests, have the main hallmark that they are especially composed of what is calcium carbonate. Also do not overlook that they have their origin in what are warm seas and have very shallow depth.
However, granite rocks, slate, arches, roots, quartzites can also be mother rocks ...
Mother Rock is also the name that receives the rock where the Petroleum , which then goes to a reservoir rock .
