A deposit of earth, sand, or gravel, containing valuable mineral in particles, especially by the side of a river, or in the bed of a mountain torrent.
A mineral deposit that has achieved its present distribution through the prior action of moving water or wind. Placers are usually in poorly consolidated materials and are the sources of much, but not all, tin, titanium, rare earths, diamonds, and zirconium, and some gold.
clastic sedimentary deposit of a valuable mineral or native metal in unusually high concentration, usually segregated because of its greater density.
Surficial mineral deposit formed by deposition of eroded rock products by some mechanical agency.
A deposit of gravel or sand containing particles of gold that can be washed out. Usually eroded from the hills or deposited by a river.
A mineral deposit formed by the sorting or washing action of water. Placers are usually deposits of heavy minerals, such as gold.
an alluvial deposit that contains particles of some valuable mineral
used interchangeably with alluvial, especially in the US.
Gold-bearing deposit made up mainly of gravels which have been subject to alluvial or glacial activity.
Generally, this word refers to deposits of gold-bearing gravel. (See Deposits)
A deposit of sand and gravel containing valuable metals such as gold, tin, or diamonds.
an alluvial or glacial deposit containing particles of gold or other valuable minerals.
A surface mineral deposit formed by the mechanical concentration of mineral particles (usually by water). In the preserve, the waters of Coal Creek concentrated the heavier gold in the irregular stream bottom while the lighter minerals were washed downstream.
A waterborne deposit of sand or gravel containing heavier minerals like gold that have been eroded from their original bedrock and concentrated as small particles that can be washed out.
A deposit of valuable minerals, in particular gold in alluvial sand or gravel.
A mineral deposit usually formed by rivers and streams which concentrate the heavy mineral particles such as gold.
A surface mineral deposit formed by mechanical concentration of mineral particles from weathered debris.
a deposit of sand, gravel, or eath in the bed of a stream, containing particles of gold or other valuable minerals with high specific gravities. [AHDOS
A deposit of heavy mineral particles (e.g., gold) that have weathered out of the bedrock and been concentrated mechanically, usually by the action of streams.
