The correct answer is: All of the above.
Mineral deposits can be found in all types of rock formations, including sedimentary, volcanic, and metamorphic rocks. Sedimentary rocks are formed when sediments, such as sand, mud, and gravel, are deposited and compacted over time. Volcanic rocks are formed when magma or lava cools and solidifies. Metamorphic rocks are formed when existing rocks are subjected to heat and pressure.
In Mizoram, mineral deposits have been found in all three types of rock formations. For example, coal is found in sedimentary rocks, bauxite is found in metamorphic rocks, and limestone is found in both sedimentary and metamorphic rocks.
The type of rock formation that is most likely to contain mineral deposits depends on the type of mineral being sought. For example, gold is often found in quartz veins, which are typically found in igneous rocks. However, there are many exceptions to this rule, and mineral deposits can be found in all types of rock formations.
The presence of mineral deposits can be detected by a variety of methods, including geophysical surveys, geochemical surveys, and drilling. Once a mineral deposit has been discovered, it can be mined and processed to extract the valuable minerals.
