Question

The mineral found in igneous rocks is:

• A. Phosphate
• B. Salt
• C. Zinc
• D. Graphite

Hint:

Igneous rocks are rich in minerals such as quartz, feldspar, and mica. Graphite, while it can form in igneous environments, is more commonly found in metamorphic rocks due to the intense heat and pressure they undergo.

Answer 1

The Correct Option is D

Igneous rocks, which are formed through the cooling and solidification of magma or lava, contain a variety of minerals. Among the options given, graphite is the mineral most commonly associated with igneous rocks, especially in the form of metamorphic rocks like schist. Graphite is a naturally occurring form of carbon, and while it is not the most abundant mineral in igneous rocks, it can be found in certain igneous environments, particularly in metamorphic or high-temperature settings.
