Contents Of A Geology Map

By Louie Ohara


A geology map is usually a representation of different functions in a given location. It represents geological functions within a offered nation or location. The map is normally printed on top of a normal map which is generally known as the base map. The objective of the base map is to aid the user locate the precise place where a certain function is located. Different colors and symbols are utilized to distinguish the distinct geological features. Every feature is shown using a distinct colour or symbol. Some of the significant elements of the map include metamorphic geology, igneous geology, structural geology and sedimentation.

A geology map shows sedimentary rocks in a given area. Sedimentary rocks are the ones that are usually formed through the accumulation of sediments. There are three kinds of sedimentary rocks namely clastic sedimentary rocks, organic sedimentary rocks and chemical sedimentary rocks. Clastic sedimentary rocks are usually formed from the mechanical weathering debris. Organic rocks include the coal and limestone and therefore are formed by animal and plant debris. Chemical sedimentary rocks are formed when the dissolved materials in a solution precipitate.

Yet another component of the geology map is the igneous rocks. These rocks are also known as the fire rocks. The rocks may either be formed on the ground or underground. Underground rocks are formed when magma, also referred to as melted rock becomes trapped in small pockets. As the magma cools, it becomes an igneous rock. The rocks can also be formed when there is a volcanic eruption resulting in the magma to increase above the ground. In such cases, the magma is referred to as the lava.

A geology map also focuses on metamorphism. Metamorphism is the procedure by which igneous or sedimentary rocks undergo solid state changes. This takes place as a result of agents of metamorphism which include heat, chemical fluids and pressure. There's two kinds of metamorphic rocks including the foliated and also the no foliated rocks. Foliated sedimentary rocks are the type that have a layered appearance and are usually formed as a consequence of presence of pressure and heat. No foliated do not have a layered appearance and therefore are usually formed high is no pressure.

Structural geology can also be included in a geology map. The map shows different structures like the folds, faults, lineaments, synclines and anticlines. Structural geology is important for different processes. For example it's important within the construction of dams, highways and power plants. It helps with search for resources such as petroleum. Understanding more about the ground surface is essential in order to have a strong foundation for any project.

All of the aspects of a geological map are very important for one reason or another. It helps professionals to solve problems that exist in the environment. The supply of the information works well for avoiding problems such as landslides. It is much easier to discover resources and possibilities using the map. Students taking courses in geology can also benefit from the maps.
