Answer: heavy eroded particles settle out of moving water

Placer deposits forms when rocks weathered due to the effect of water. The heavy minerals from the rocks get settled down in water. Minerals that form placer deposits have high specific gravity, they are resistant to chemical weathering process and are durable.
