Statement Analysis:
Statement 1: Minerals in igneous and metamorphic rocks occur in beds or layers.
Statement 2: Minerals in sedimentary rocks occur in ‘veins’ and ‘lodes’.
Explanation:
Igneous Rocks: These rocks are formed by the solidification of molten magma or lava and are classified into intrusive and extrusive rocks. Intrusive rocks form below the Earth's surface and cool slowly, whereas extrusive rocks form on the Earth's surface and cool quickly. The mineral crystals in igneous rocks typically form as interlocking crystals or grains, and they do not occur in beds or layers.
Metamorphic Rocks: These rocks are formed by the transformation of pre-existing rocks due to heat, pressure, and chemical changes. Metamorphic rocks do not have beds or layers of minerals but instead have mineral crystals that are oriented in a certain direction due to the pressure they were subjected to during their formation.
Sedimentary Rocks: These rocks are formed by the accumulation of sediments, which may include fragments of pre-existing rocks, minerals, and organic matter. The minerals in sedimentary rocks are typically found in veins and lodes, which are deposits of minerals that have been concentrated in one area.
Conclusion:
Neither statement 1 nor statement 2 is correct. The occurrence of minerals in rocks depends on the type of rock and the conditions under which it was formed. In general, minerals in igneous and metamorphic rocks occur as interlocking crystals or grains, while minerals in sedimentary rocks occur in veins and lodes.

- Minerals are usually found in “ores”. The term ore is used to describe an accumulation of any mineral mixed with other elements. The mineral content of the ore must be in sufficient concentration to make its extraction commercially viable. The type of formation or structure in which they are found determines the relative ease with which mineral ores may be mined.
- This also determines the cost of extraction. It is, therefore, important for us to understand the main types of formations in which minerals occur. Minerals generally occur in these forms:(i) In igneous and metamorphic rocks minerals may occur in the cracks, crevices, faults or joints. The smaller occurrences are called veins and the larger are called lodes. Thus statement 1 is incorrect. In sedimentary rocks a number of minerals occur in beds or layers. They have been formed as a result of deposition, accumulation and concentration in horizontal strata. Thus statement 2 is incorrect.
