Justification: Statement 1: Iron-ore innorth 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.
Statement 2:Limestone deposits of Caucasusregion of France, manganese deposits of Georgia and Ukraine and phosphate beds of Algeria are some examples. Mineral fuels such as coal and petroleum arealso found in the sedimentary rocks.

Explanation:
Statement 1: Generally metallic minerals are found in igneous and metamorphic rock formations that form large plateaus.
Metallic minerals are minerals that contain metals in their composition and are used for various purposes such as construction, manufacturing, and energy production. These minerals are usually found in igneous and metamorphic rock formations that have undergone intense heat and pressure.
Igneous rocks are formed from the solidification of molten magma or lava. They can be classified into two types - intrusive and extrusive. Intrusive igneous rocks, such as granite, are formed deep within the Earth's crust and have large mineral crystals. Extrusive igneous rocks, such as basalt, are formed on the Earth's surface and have smaller mineral crystals.
Metamorphic rocks are formed from the transformation of existing rocks through heat and pressure. This process causes the minerals in the rocks to recrystallize, resulting in the formation of new minerals. Examples of metamorphic rocks include marble and slate.
Large plateaus are often formed by the uplift and erosion of igneous and metamorphic rocks. These plateaus provide favorable conditions for the accumulation of metallic minerals. The minerals are usually concentrated in veins or layers within the rock formations.
Therefore, statement 1 is correct.
Statement 2: Sedimentary rock formations of plains and young fold mountains contain non-metallic minerals.
Sedimentary rocks are formed from the deposition and compaction of sediments over time. They are typically found in plains and young fold mountains, which are characterized by gentle slopes and relatively recent geological activity.
Non-metallic minerals are minerals that do not contain metals in their composition and are used for various purposes such as building materials, fertilizers, and industrial products. Examples of non-metallic minerals include limestone, gypsum, and salt.
The deposition of sediments in plains and young fold mountains creates favorable conditions for the accumulation of non-metallic minerals. These minerals are often found in layers or beds within the sedimentary rock formations.
Therefore, statement 2 is correct.
Conclusion: Both statement 1 and statement 2 are correct. Generally, metallic minerals are found in igneous and metamorphic rock formations that form large plateaus, while non-metallic minerals are found in sedimentary rock formations of plains and young fold mountains.
