[QUOTE="user 4386, post: 647921, member: 4386"] . One is a process of removing all except the gold and coarse rock fragments at the original site, the other of it then moving down the hill under gravity. It is really a continuum until it reaches the base of slope where it accumulates in colluvium. Colluvium does not really represent an efficient gold concentration process, just a way of accumualting a large volume of gold-bearing soil, So you don't see much discussion of colluvial gold deposits - it tends to be called eluvial much of the way down the slope even though you are transitioning into moving it away from its source by water and gravity. Sometimes the term residual is used for right on top of the original source area. All names - think processes as you say, that is what helps find gold. [/QUOTE]
