Overview of Metallic and Non-Metallic Minerals
Understanding the distribution of metallic and non-metallic minerals is essential in geology and resource management. Let’s analyze each statement to clarify their correctness.
Statement 1: Metallic Minerals in Igneous and Metamorphic Rocks
- Metallic minerals are typically found in igneous and metamorphic rocks because these rocks are formed under high temperatures and pressures, conditions conducive to the formation of metallic deposits.
- Large plateaus, often formed by volcanic activity or tectonic uplift, are common locations for these types of minerals.
Statement 2: Non-Metallic Minerals in Sedimentary Formations
- Sedimentary rock formations, particularly in plains and young fold mountains, are known to contain non-metallic minerals like limestone, gypsum, and salt.
- The formation processes of these rocks often involve sedimentation, which leads to diverse mineral deposits that are primarily non-metallic.
Statement 3: Organic Formation of Sedimentary Rocks
- Sedimentary rocks can indeed form organically. For instance, limestone can form from the accumulation of shells and coral, while coal is created from the remains of plant material.
- This process illustrates the biological contribution to sedimentary rock formation, confirming that not all sedimentary rocks are purely clastic or chemical in origin.
Conclusion
- All three statements are correct. Therefore, the correct answer is option 'D': All of the above.
- This understanding is crucial for resource exploration and management in various geological settings, particularly in the context of sustainable development and environmental considerations.

- Iron ore in north Sweden; copper and nickel deposits in Ontario, Canada; iron, nickel, chromites and platinum in South Africa are examples of minerals found in igneous and metamorphic rocks.
- Limestone deposits of Caucasus region of France, manganese deposits of Georgia and Ukraine and phosphate beds of Algeria arc are some examples. Mineral fuels such as coal and petroleum are also found in the sedimentary rocks.
- Sedimentary rocks are classified into three major groups as follows:
(1) Mechanically formed conglomerate limestone, loess, sandstone, shale, etc.
(2) Organically formed chalk, coal geyserite, limestone, etc.
(3) Chemically formed chert, limestone halite, potash, etc.
