Detailed Solution

The above statement is true. In igneous and metamorphic rocks, minerals may occur in cracks, crevices, faults and joints.
Minerals are natural compounds that appear in many forms in nature. Rock is defined as an accumulation of two or more minerals. Minerals usually get found in the joints, faults, fissures, and cracks of igneous and metamorphic rocks. Veins and lodes are the occurrences of minerals of different sizes in igneous and metamorphic rocks. The smaller ones are veins, and lodes are the larger ones. They were created as gas, and liquid minerals are driven upward through cavities and towards the earth's surface. As they ascend, they cool and solidify. Tin, copper, zinc, and lead got extracted from veins and lodes.
