Gold is usually found in certain geological environments: • Igneous rocks → Especially granites and volcanic rocks, where hydrothermal fluids deposit gold in veins. • Metamorphic rocks → Schist, greenstone, and slate often contain gold, especially along fault zones. • Sedimentary rocks → Gold can accumulate in riverbeds and ancient alluvial deposits (placer gold). In simple terms: gold likes to hide in quartz veins within igneous and metamorphic rocks, and it can also be w
