Dome


In the geological context, a dome is a kind of dome, with a slightly undulating and rounded relief. A dome is a fold of the earth’s crust, whose shape is due to an igneous intrusion, where the raised superficial layers are rapidly eroded and come to form structures of peaks or concentric cusps made up of the layers most resistant to erosion.

There are different types of domes:

The sedimentary dome: is an anticline dome in sedimentary structures.

The granite dome: is the one created by the erosion of the sedimentary layers that cover a laccolith, showing the igneous rocks that make them up.

The saline dome: It is the one that is created by the condensation of salt, in the places where the upper layers bulge. This type of dome is very important at an economic level since it originates oil “traps”.

The oil dome: they are species of folds of the earth’s crust raised to a certain depth by the condensation of hydrocarbons and the increase in pressure caused by natural gas.

The ice dome: it is the main element of the ice cap. It extends symmetrically in the form of a bulging parabola over a land mass.

There are domes, which if they are very isolated, are very outstanding mountains, representing a symbol of the area where they are located. Some more outstanding domes are:

Sugar Loaf, in Rio de Janeiro (Brazil); Pico El Yelmo, in Madrid (Spain); Cocuy Stone (Venezuela); Piedra del Peñol (Colombia), among others.

On the other hand, in the architectural context, a dome is a structure in the shape of a half sphere that is used to build houses, sports centers, churches, warehouses, etc. Domes are dazzling structures that do not require columns or supports that fill their interior design with complexity.

Some of the advantages that domes provide at the building level are:

The manufacturing cost is much cheaper, compared to other traditional buildings.

They are energy efficient.

They have a unique shape.

They are very safe structures.

They are structures that provide protection against tornadoes or hurricanes.

They are very useful structures for the storage of large volumes of materials.
