[QUOTE="Diggerdude, post: 5528, member: 308"] Greenstone= jade?? Don't reckon that's correct. Maybe in nz. Most of the greenstone belts associated with gold in Aus are ancient basalt. ( it is not an actual rock type but rather a term used for metamorphised belts of basalt and granite ). They are often heavily folded from continental movement and intruded by granites. Because of there extreme age they often have lots of cracks that have been filled with quartz, long after the basalt formed. So it also has nothing to do with the temperature of the rock. This is where you often get gold disseminated though the greenstone near the contact with quartz. Hope this clears it up for you all. DD [/QUOTE]
