[QUOTE="Wally69, post: 364219, member: 1916"] Spot in Heath - camped at the Mudgee end of Burrangdon Dam for a couple of days and went for a day trip to sample the Hill End coffee. Stopped into spinel gully on the way to the 'cow bell pub' site to swing the 705 over the missing cow bell part......or a lost sovereign. Wasn't expecting anything from spinel gully as we covered the area very well last time with Reeks. A bit of heavy rain between now and then bought enough to the surface to keep my boys entertained., was quite surprised. Not sure how to tell the difference between black spinel and obsidian. There is no light getting through the stones at all but the fractured faces in the host-rock samples look very glassy. The spinel theory probably holds if this area was limited in aluminium and high in magnesium, would explain why there are no pretty blue stones amongst them. Don't know enough about obsidian, not sure if it can float around in magma and can get caught in the matrix or if it is just generated by mass-cooling of magma. The challenge of explanation for wiser men than me has been set 8) [/QUOTE]
