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 Send me the next one 📸
