[QUOTE="fossickeract, post: 290149, member: 3672"] The Cambewarra flow is called a porphritic latite however with the depth of the flow there is considerable variation. This is oldish late Permian 200my but there is several post Triassic intrusions lamprophyre, which have come through the older volcanics 17-24 million years ago, and its one of those I associate with much of the silica mineralisation here. The specimens following have been found as a distinctive volcanic plug is approached along one arm of Kangaroo Valley.[img]https://www.prospectingaustralia.com/forum/img/member-images/3672/1479093322_img_0101-optimized.jpg[/img] 10k from the plug above and below showing bark,growth rings, worm holes and decayed core. [img]https://www.prospectingaustralia.com/forum/img/member-images/3672/1479093470_img_0098.jpg[/img] These following two have been found about5k from the plug.
