Alluvial deposit, Material deposited by rivers.It consists of silt, sand, clay, and gravel, as well as much organic matter.Alluvial deposits are usually most extensive in the lower part of a river's course, forming floodplains and deltas, but they may form at any point where the river overflows its banks or where the flow of a river is checked.. They yield very fertile soils, such as those ...
There is a very comprehensive list of locations where alluvial gold has been found in Tasmania in Ralph Bottrill's booklet 'Alluvial Gold in Tasmania', which is a free download (PDF) from the MRT library. However, the grid coordinates provided in this book are a mix of AGD66 and GDA94 datums, and there is no indication of which is which ...
The gold discover y at Swamp Oak Creek led prospectors to other alluvial deposits along the Peel River catchment, including in the present drainage, high-level terraces and old valley leads buried...
Because gold is heavier than most of the material moved by a creek or river, it can become concentrated in hollows and trapped in the bed of the river. These are known as secondary (alluvial) gold deposits and they can be worked using a gold pan or cradle. Alluvial gold deposits sparked the Australian gold rushes of the 1850's. Resources

In and below the clay no gold occurs. Gold recovered was in the form of nuggets of all sizes — from a fine dust to 4 ounce nuggets — or appeared as gold within quartz.
Gold prospecting and identifying gold-bearing areas have become increasingly more feasible, due to research developments on the geological process of gold formation. (See References 1.) Gold bearing areas, mostly throughout the western United States, have drawn and sprouted entire communities based on prospecting. ...

The State Library Victoria and National Library of Australia contain a wealth of digitised resources, many of which provide valuable information for the modern day gold prospector. Historical maps provide insights into the geological features and gold mining operations of the past, helping prospectors to determine ideal locations to search for gold.
Alluvial soil is rich in minerals and nutrients -- highly fertile, and a good crop soil. It often contains gravel, sand and silt. The chemical content of the soil will depend on where it is located. The topography of the land will influence what runs off into the river that eventually forms the alluvial soil. One example is the volcanic pumice ...
Where Guatemala is located now (it took millions of years for tectonic plates to move and form new continents) before there were algaes and in the Motagua fault you can see sometimes presence of antique algae and some carbon because of that dead algae. then, if gold loves carbon. antique gold is moving in the alluvial gold found in the ...
Western Australia produced over 50% ($69.5 billion) of all Australian mineral and petroleum sales, which made up 88% of the state's merchandise exports in 2015-16.

Alluvial Gold Mining. Alluvial gold is found beneath the surface at the bottom of a creak or stream. Alluvial gold mining is the process of extracting gold from these creaks, rivers and streams and is generally considered to be the most environmentally friendly method of gold mining as a result of the reduced environmental impact when compared to underground mining.
Alluvial gold, in comparison, can be found in unconsolidated rocks and sediments at, or close to, the surface, and can be more readily mined and recovered. Allu vial dep osits are u sually foun d close to l ode deposit s and are formed by p rolonged erosion of such dep osits, rel easing the gold into the soil and being transported and deposited
Alluvial Gold (Deposited by water movement) and Eluvial gold (disintegration of rock at the site where it originates - not there through water movement) are essentially primary gold broken down by weathering and erosion and transported by gravity or water movement over many millenia of geological time.
