[QUOTE="user 4386, post: 483027, member: 4386"] Yes, common, the clay is usually just a more weathered version of the hard rock that you are used to. A few million years ago most surface rock was converted to clay in much of Australia, but in many areas the soft clay has since eroded away again so the hard rock is exposed. At that time forests similar to those of Tasmania extended all the way to Broken Hill (i.e. it was much higher rainfall). If there was a quartz vein in hard rock, it will still look the same when the rock is completely weathered to clay. [/QUOTE]
