[QUOTE="Conrad, post: 632576, member: 16362"] Re #22: looks like the surface expression of a structure that is eroding differently to surrounding material, maybe more brittle, less affected by chemical weathering. That would explain coarser texture. Iron rich judging by the reddish colour. Why not just a gold hosting quartz/iron rich vein or pod? It's very common for veins of quartz (for example) to be expressed at the surface as a concentration of scattered pieces of broken quartz, as normal erosion processes tend to break up and separate exposed quartz veins. The same would be true of any harder, brittler and less soluble rock or mineral masses. [/QUOTE]
