lodes and veins in igneous and metamorphic rocks

placer deposits in river beds

beds and layers in sedimentary rocks

Answer 2

☘️ Answer:

1. Igneous and metamorphic rocks, minerals occur in the cracks, crevices, faults and joints. Zinc is mind in this way. They are formed when minerals in their liquefied/gaseous was forms are forced upwards to the Earth's surface through activities. They cool and sulphide as they rise.
2. In sedimentary rocks, they occur in beds and layers as a result of decomposition, accumulation and concentration in horizontal streta. Coal and iron are found in this way. Gypsum, potash and sodium salt are another class of sedimentary salt which are obtained through evaporation in arid areas.
3. Bauxite is found by the decomposition of surface rocks and its removal of soluble constituents leaving a residual mass of whethered material containing ores.
4. Gold and silver are found as placer deposit s in the sands of valley floors and base of hills.
5. Seawater contain magnesium and bromine salts. Magnesium nodules are found in the sea beds.
