[QUOTE="fossickeract, post: 288577, member: 3672"] Lefty, Some of the petrified wood from Kangaroo Valley that replaced by chalcedony or jasper is glossy on the outside, some shows obvious burning on the margins which has been fossilised as well.Much of it is dull grey on the outside tumbled in a river. Yes Geology is a solid Science but the net is not and sweeping generalisations based on info from US websites perhaps valid with regard to Arizona should not be taken as gospel for conditions here.Yes my geo qualifications are pre-internet. Interestingly I have found baked cobblestones in deepleads where lava has flowed down ancient river valleys and turned them to citrine high temperatures indeed. Good that you moved Springsure back to central Queensland because I like a bit warmer when I travel through, than the New England in June. :) Ted [/QUOTE]
