Question

During the process of alluvial deposit which of the following minerals is more likely to occur?
A. Gold
B. Nickel
C. Iron ore
D. Lead

Answer 1

Hint:
It is one of the most precious metals in the world and is very costly.

Complete answer:
Alluvial deposit means the material which will get deposited by the bank of the river as it would consist of sand, salt, clay and gravel, and all the other organic matter. Alluvial deposits are usually found in the most lower part of the river that is in the floodplains and deltas. It may be overflowed when the river has much water it may go to the bank or it may be at the point where the flow of the river is checked. The solid that has been yielded is very fertile soil which can be found at the deltas of Ganga, Brahmaputra, etc. It would contain most of the tin ore as it is the world’s supply and as well as in some regions we can find gold, platinum, and gemstones.

There are more chances that they would find Gold rather than any other metal like lead nickel or Iron ore. Gold is a very precious metal and can be found rarely. As it is the most common type of placer gold which can be found rarely is often the richest in the form. One could get pieces of gold which has been washed by the water through heavy force.

Hence, the correct answer is option A.

Note:
 Gold is a very rare metal that has been found mostly in the valleys or could also be found at the flood plains.
