[QUOTE="user 4386, post: 653731, member: 4386"] I guess in many cases "stringer reefs" (really just thin quartz veinlets) arequartz veins, that occur in the same regions as major reefs, but that it did not pay for the goldminers to chase because it takes a lot of mining to get a tonne of gold-quartz ore out of them. Also they were harder for them to find if isolated, and are more inclined to peter out but be replaced by others nearby (so may keep recurring in the same "package" of rocks, often following a single structure, eg anticlines in Victoria).. These are often only cms thick. The fact that they are thin does not mean that they cannot be rich (often they are - I have seen quartz veins only one cm thick that were 10% gold)). The old-timers did not have detectors to find the coarse gold in them - you do. Sometimes as WalnLiz say, they can be offshoots of a larger reef but in other cases they just occupy thin fractures that formed at the same time as the big reefs, but were not connected to them. Nevertheless, they can often occupy the same fold structure as bigger reefs even when the bigger reefs may be absent. [ATTACH type="full"]4842[/ATTACH] [/QUOTE]
