So gold in a stream is held in place by gravity and resists movement due to its weak buoyancy and strong inertia. There are several types of placer deposits. There are alluvial placers, eluvial placers, beach placers, eloian placers and paleo-placers.

In geology, a placer deposit or placer is an accumulation of valuable minerals formed by gravity separation from a specific source rock during sedimentary processes. The name is from the Spanish word placer, meaning "alluvial sand". Placer mining is an important source of gold, and was the main technique used in the early years of many gold rushes, including the California Gold Rush.
