Alluvial soil is the debris/talus from weathering/erosion of mountain rocks. If the mountain rock is granite, the alluvial is the breakdown components of it which are clay, silicon and mica sand. This so called alluvial soil will be deposited around foothills and perhaps further down if acted by river system.

My take on this one : ....By the same token the mountain soil should be the "in situ" weathered/eroded mountain rocks which have not been transported away from the mountain yet.
