Answer
A
A placer deposit is an accumulation of valuable minerals formed by gravity separation from a source rock during sedimentary processes. These deposits are typically found in riverbeds, beaches, or other environments where water currents have concentrated heavy, durable minerals.
- A: Gold is a classic example of a mineral found in placer deposits due to its high density and resistance to weathering.
- B: Copper is typically found in vein deposits or disseminated in igneous and metamorphic rocks, not commonly as placer deposits.
- C: Iron ores are usually found in banded iron formations or lateritic deposits, not typically as placer deposits.
- D: Coal is an organic sedimentary rock formed from plant matter and does not form placer deposits.
Therefore, gold is the correct answer.
The correct option is A.
A) Gold
