[QUOTE="user 4386, post: 519859, member: 4386"] In this photo you can see a black dyke of monchiquite ("lava dyke" or "lamprophyre dyke") cutting through an earlier gold-bearing quartz vein, Central Deborah mine, Bendigo. So although the dykes in the previous photos that I posted would be good to chase for gold, this type would not be as it is hundreds of millions of years younger than the gold-bearing quartz vein. This is a very narrow dyke but they are typically much thicker (but it is easier to see the cross-cutting relationship with this narrow dyke photo).
