[QUOTE="Chimpy, post: 39879, member: 555"] G'day this is an image of the 'subduction model' thought to create our diamonds (model for the Bingara region) [img]https://www.prospectingaustralia.com/forum/img/member-images/555/1384768832_lge_subduction_dia_model.jpg[/img] Nobody is 100% sure though because no primary diatremes or pipes have been located to date. I did hear a theory that there is a thermal hot-spot that the east side of NSW has been moving over as the continental plate drifts north. I don't know if there is solid evidence of this but the map of occurences does suggest this could be a possibility if you combine it with the subduction theory of formation. A thorough search of the DIGS database will turn up plenty of interesting reports and info. I've entertained the pipedream (literally ;) ) of hunting down a 'diamond pipe', as have many before me, and done a fair bit of research but thats as far as I've got. The mystery continues......
