[QUOTE="Metamorphic, post: 109442, member: 3682"] I have only prospected in Victoria and have found that foliation in Slate reefs, sandstone, granite etc, commonly run North/South with slight variations to the NNW/SSE. (In fact, in all my observations) Veins, stringers, leaders, shoots and the like running from these reefs, are generally not determined by foliation structure, but rather by 'secondary' faulting/sheering etc through a re occurrence of hydro-thermal activity many moons ago, after the original reef had been formed! These features are generally higher in concentration of precious metals as they have had a secondary enrichment. Cheers ;) Tip: Bends and turns in a vein are the most likely places for gold to accumulate. In the formation of veins, as the fluid silica, (quartz) passes a corner it creates a static charge, and this in turn creates gold deposits.....usually! hehe Changes in the host rock along the veins are also important, any natural formations where these 'fluid flows' meet resistance and become 'trapped' are vital area's.
