If you wanted to find a region rich in a particular type of rock, which type of map would you use?

To find a region rich in a particular type of rock, I would go for a geologic map.

Explanation:

A geologic map of a particular area specifically displays the terrain/landform in regard to the physical features of the area and their compositions. It not only indicates the availability of a specific feature but also shows its distribution of the feature over the area. The standard geologic maps have different colors and letters assigned to each of the different features for the convenience of the readers of the map. In most cases, geologic maps only serve geologists and prove of no use to the ones who have no knowledge of the discipline of geology.
