Understanding McDermitt: Characteristics, Origin, and Economic Significance

McDermitt is a type of volcanic rock that is rich in magnesium and iron. It is named after the McDermitt Caldera, a large volcanic field located in western North America.

2. Where is McDermitt found?

McDermitt is found in the McDermitt Caldera, which is located in western North America, primarily in the states of Oregon and Nevada, but also extending into California and Idaho.

3. What are the characteristics of McDermitt?

McDermitt is a type of volcanic rock that is characterized by its high magnesium and iron content. It is typically fine-grained and has a distinctive texture that is formed from the cooling and solidification of magma. McDermitt can range in color from pale gray to dark brown, and it often contains small amounts of other minerals such as pyroxene and olivine.

4. What is the origin of McDermitt?

McDermitt is thought to have formed as a result of the partial melting of the Earth's mantle, which is the layer beneath the crust. This melting occurred due to the presence of hotspots, which are areas where the mantle is partially melted and buoyant. As the magma rose through the crust, it cooled and solidified, forming the McDermitt volcanic field.

5. What is the economic significance of McDermitt?

McDermitt is not typically mined for its own sake, but rather as a source of valuable minerals such as gold, copper, and silver. The deposits of these metals are often found in the form of veins or deposits that are associated with the McDermitt rock formations. As such, the economic significance of McDermitt is primarily as a source of these valuable minerals.
