Types of deposits

comparisons

The types of deposits are those ways in which we can classify geographic areas with concentrations of natural resources, mainly minerals and hydrocarbons. Although we can also refer to archaeological heritage.

There are many ways to classify the different types of deposits, either in relation to their content, the way in which the resource is distributed, its age, its topography (depending on the soil where it is found).

Next, we will present some of the existing classifications of deposits, distinguishing, in the first place, the geological from the archaeological ones.

Types of geological deposits

Geological deposits can be divided in different ways, although we can find these main categories:

  • Non-ferrous metals: Non-ferrous minerals are those that do not have iron in large quantities in their chemical composition, as in the case of aluminum, copper, lead, nickel, tin, titanium, zinc, gold, silver, among others.
  • Ferrous Metals: Ferrous minerals are those that are composed mainly of iron and small amounts of other metals. This is the case of hematite, magnetite and siderite.
  • Fuel: Natural gas, oil and coal reserves.
  • Precious stones: deposits of diamonds, rubies, sapphires, emeralds, among others.

At this point, it is worth emphasizing that there are very complex ways of classifying geological deposits. For example, those endogenous are those that are located in deep areas of the earth, while the exogenous ones are located near or on the surface.

Types of archaeological sites

Archaeological sites can also be classified in different ways:

  • According to the chronology: The site can be classified according to the historical period of its origin. For example, it may belong to the Paleolithic or Neolithic.
  • Based on a civilization: It can be a Phoenician, Greek, Roman, Mayan, Inca or other site.
  • According to their function: Two main types of reservoir are distinguished based on the function they fulfilled:
    • Habitat: It was the space where social activities such as trade and religious ceremonies were carried out. The more advanced a civilization is, the more complex are the remains, buildings and utensils that it has left for posterity.
    • The necropolis: They are the spaces where the deceased were worshiped. We refer, for example, to the tombs of the Egyptian pharaohs.
  • According to its topographic situation: The site can be located outdoors, inside a cave, on the top of a mountain or in the middle of a valley.
