Geologists at Ohio State University used software techniques to map the location of possible metal deposits in the western Shield area of the Saudi Arabian Peninsula, outlined here in red. The Sheild, which contains a mix of mountain and lowland terrain, is about equal in size to the state of Texas, and may contain large deposits of metals such as gold, silver, copper, and iron ore.

This map, created by geologists at Ohio State University, charts locations of possible copper deposits in Saudi Arabia, with dark blue indicating a high potential that a deposit exists. The map inset marks in red the areas that are already known to contain copper. Using software techniques, the geologists determined that the country contains more than 5,000 square miles of potential copper deposits. [Map courtesy of Ohio State University.]
This map, created by geologists at Ohio State University, charts locations of possible gold deposits in Saudi Arabia, with dark blue indicating a high potential that a deposit exists. The map inset marks in red the areas that are already known to contain gold. Using software techniques, the geologists determined that the country contains more than 5,000 square miles of potential gold deposits. [Map courtesy of Ohio State University.]
This map, created by geologists at Ohio State University, charts locations of possible iron ore deposits in Saudi Arabia, with dark blue indicating a high potential that a deposit exists. The map inset marks in red the areas that are already known to contain iron ore. Using software techniques, the geologists determined that the country contains more than 3,000 square miles of potential iron ore deposits. [Map courtesy of Ohio State University.]
This map, created by geologists at Ohio State University, charts locations of possible silver deposits in Saudi Arabia, with dark blue indicating a high potential that a deposit exists. The map inset marks in red the areas that are already known to contain silver. Using software techniques, the geologists determined that the country contains more than 300 square miles of potential silver deposits. [Map courtesy of Ohio State University.]
