A placer deposit is a type of mineral deposit that forms when valuable minerals are concentrated by the action of water, typically in riverbeds, beaches, or other sedimentary environments. These deposits occur when heavy minerals, such as gold, platinum, or gemstones, are eroded from their source rocks and transported by flowing water. As the water slows down in certain areas, the heavier minerals settle and accumulate, forming concentrated deposits. Over time, these accumulations can be mined for their valuable resources.

Most stalactites are limestone. Water, often rainwater, seeps through material which causes it to absorb carbon dioxide, as it seeps further it dissolves limestone. Then when it reaches the ceiling of a cave it slowly begins to forms droplets. As these dry they deposit the limestone on the ceiling. This happens again and again, one drop at a time, and very slowly over years this deposit grows forming a stalactite.
