What is the geologic location?

What is the geologic location?

Geologic maps represent the distribution of different types of rock and surficial deposits, as well as locations of geologic structures such as faults and folds. Geologic maps are the primary source of information for various aspects of land-use planning, including the siting of buildings and transportation systems.

Where are metal deposits found?

Mineral deposits have been found both in rocks that lie beneath the oceans and in rocks that form the continents, although the only deposits that actually have been mined are in the continental rocks. (The mining of ocean deposits lies in the future.)

What are the essential parts of a geologic block diagram?

A block diagram shows the surface of the earth and also at least one cross section. It is like a block or chunk cut out of the earth. Again, think of it like a whole slice of cake. You can move around and look at it from different angles and see the top and the layers of cake and icing beneath it all at the same time.

What are geologic structures found near the location of?

The structures that can be found near the location of metallic deposit are volcanoes and trenches. Gold, copper, iron, chromite, cobalt and other metals are seen near the volcanoes since they are a result of the change in temperature and state of the lava inside the volcanoes that were not released during the eruption.

Which is the only remnant of a weathered metallic deposit?

A rusty, iron‐bearing cap called a gossan is often the only remnant of a weathered metallic ore deposit at the surface. Finding a gossan may indicate additional minerals exist below the zone of weathering. Most metallic ore deposits are a result of plate tectonic activity.

What are the different types of metallic deposits?

Metallic Deposits. Common types of hydrothermal deposits are contact metamorphic, hydrothermal, disseminated, and hot springs deposits. Contact metamorphic deposits result from hot solutions that migrate from a cooling intrusion and deposit minerals in cracks in the surrounding country rock.

Where does the metal in hydrothermal deposits come from?

Hydrothermal deposits rich in copper, lead, zinc, gold, silver, molybdenum, tin, mercury, and cobalt form from hot solutions that circulate through fractured country rock. The solutions come from nearby intrusions or heated meteoric water.
