Question

Answer

The correct option is A.
Major metallic minerals like tin, copper, zinc and lead etc. are obtained from veins and lodes. sodium salt. These are formed as a result of evaporation especially in arid regions.

Answer

In igneous and metamorphic rocks minerals may occur in the cracks, crevics, faults or joints. The smaller occurrences are called veins and the larger are called lodes. In most cases, they are formed when minerals in liquid/molten and gaseous forms are forced upward through cavities towards earth's surface. They cool and solidify as they rise. Generally metallic minerals are obtained from veins and lodes. since Zinc is a metal, this is also obtained from them. So,  the answer is A.

Answer

The correct answer is option 'A', which is zinc.

Veins and lodes are geological formations that contain metallic minerals. They are formed when mineral-rich fluids circulate through fractures or fissures in the rocks and deposit their contents. These fluid-filled cracks are often found in the Earth's crust, and they provide pathways for the movement of minerals.

Zinc is one of the metallic minerals that is commonly obtained from veins and lodes. Here are the reasons why zinc is obtained from these formations:

1. Formation: Zinc deposits are typically formed in hydrothermal environments, where hot fluids carrying zinc minerals rise to the surface through fractures in the rocks. These fluids cool and deposit their contents, forming veins and lodes rich in zinc.

2. Association with other minerals: Zinc ores are often associated with other minerals such as lead, copper, and silver. These minerals can also be found in veins and lodes, making them important sources of multiple metallic minerals.

3. Geological occurrence: Zinc deposits are commonly found in sedimentary rocks, particularly in areas where there has been tectonic activity. The movement of Earth's crust can create fractures and faults that serve as conduits for mineral-rich fluids, leading to the formation of zinc-bearing veins and lodes.

4. Mining methods: Vein and lode deposits are typically mined through underground methods. Miners follow the mineralized veins and extract the ore using drilling, blasting, and excavation techniques. This allows for the extraction of zinc and other metallic minerals from the veins and lodes.

In contrast, the other options provided in the question are not typically obtained from veins and lodes:

- Limestone is a sedimentary rock composed mainly of calcium carbonate and is usually formed in marine environments. It is not typically associated with veins and lodes.
- Rutile is a mineral composed of titanium dioxide and is commonly found in igneous rocks and beach sands. It is not commonly associated with veins and lodes.
- Mica is a mineral group that includes several different species with varying compositions. It is commonly found in metamorphic rocks and pegmatites, rather than in veins and lodes.

In conclusion, zinc is the metallic mineral that is most commonly obtained from veins and lodes. These geological formations provide the necessary conditions for the formation and extraction of zinc deposits.
