[QUOTE="shivan, post: 314075, member: 194"] Thank you very much for that info Goldierocks, it makes a lot more sense that the limestone was in the conglomerate and was replaced by the opal, than the opal forming in the limestone. As i said it can get confusing sometimes when i get conflicting information, so its a huge help getting to the bottom of it. I do understand the sugar solution is there to be converted to carbon. When i thought the Andamooka matrix was limestone, i again just assumed there must have been something protecting the calcium carbonate from the acid and all i could see was the sugar. So again this process makes more sense knowing its not a limestone matrix. I have heard of opal being found in dropstones, but never seen it myself, as i had heard of opal pseudomorphs but never seen any before. That White cliffs pineapple looks very interesting. [/QUOTE]
