Finding the existence of alluvial gold

         Genesis or eluvial gold placer deposits formed by precipitation and reconcentration gold-bearing sediments from the occurrence of primary gold. Placer deposits are generally classified according to their depositional environment. Marine placers occur offshore near the coast; fluvial placers occur in river valleys and in the watershed are analyzed that contain the incidence of primary gold upstream. In conducting searches eluvial gold vein that we need to do is find a location mountainous areas or hilly areas that have a strong granite or crystalline deposits is the good end. Area where geological upheaval has occurred and the pressure is a prime location. The place to look for gold eluvial including creeks and ditches along the sides of hills and in depressions between the hills. Eluvial deposits occur on the hillsides and in the hollows between the hills.
         Eluvial gold can be found in the low hills, rises and flat-lying areas adjacent to the
location above. This is often covered with debris of quartz and iron ore. Eluvial deposits are concentrated in the gradient changes, such as the bottom of the hill.supergene deposits found on low hills or flat-lying areas which have developed laterite profile above bedrock. Supergene gold occurrence is difficult to predict because it is controlled by a complex combination of processes
        Secondary gold occurs in saprolite laterite surface and deeper than the zone of weathering (laterite profile) and consists of the distribution of crystal grains. Chemically modified and physically transported primary grains and nuggets, derived from the original ore body, occurs at the surface and near surface with secondary deposits.
Then we tried along the river, which at the start of the bend downstream. At the next river bend in or bend because it is usually gold ore are often stuck in there. we can try to take a few handfuls of sand sediment and then washed with a platter or roll.
Then we tried along the river, which at the start of a bend in the curve of the river downstream side or bend in the river because it is usually gold ore are often stuck in there. And we can try to take a few handfuls of sand sediment and then washed with a platter
 
When the platter was found in fragments in valuable minerals, then panning in the river bend in the river passed through the next corner to the precious mineral flakes never found again.
