Question

Minerals that are heavy, durable, and chemically resistant are likely to be found in deposits.

Answer 1

Answer:

minerals that form placer deposit have high specific gravity are chemical resistant to weathering and are durable

such minerals including gold platinum copper zircon etc

Answer 2

Chemically resistant:

• Chemically resistant minerals are less likely to react with the anions like chloride, bromide, oxide, nitride, etc, to form the corresponding salts.
• Those metals that are light come to the upper layer of earth's crust. So, they are easily worn away. The heavier ones are easily found below.
• The durable ones are found actually because they are easily aggregated and doesn’t wear away. Thus, the durable ones are easily found.
