The gold in hard rock is released during the weathering process and then it carried off by glaciers or running water (streams, rivers, flood water) to someplace where it is deposited and concentrated in a placer deposit.Gold Mining BC - Kinds of Placer Deposits,Kinds of Placer Deposits A placer deposit or placer is a deposit that formed in moving water where particles/pieces of gold and/or other dense minerals have accumulated because the water flow isn't sufficient to keep them moving.. In many cases, for a placer deposit to accumulate gold over time, the water must be moving fast enough to flush out lighter sand.Placer deposit | geology | Britannica,There are several varieties of placer deposits: stream, or alluvial, placers; eluvial placers; beach placers; and eolian placers. Stream placers, by far the most important, have yielded the most placer gold, cassiterite, platinum, and gemstones.

Through geologic processes millions and millions of years ago, a gold vein forms in some type of rock. This vein is 10,000 feet up on a mountain and 20 feet under the ground. As time goes by natural erosion takes place. The rock over the vein is slowly eroding away, and after years it slowly crumbles away.

Glacial Deposits-these placer deposits are formed by glacial movement, transporting gold bearing gravel from different sources and depositing them elsewhere. Glacial gold deposits are very well known throughout the Midwest and Northeastern U.S. They are almost always characteristic of very fine gold that has been pulverized by glacial action.
