In the relevant drill core, at the bottom of the lowermost basalt flow, pieces of fossil wood still containing organic carbon were present encased in the basalt, right at the boundary of the basalt flow with the siltstone below.

Those on-site at the time speculated that there had been two distinct trees, partly standing, still organic in nature, and thus not petrified.
The imprint of a leaf was also discovered within the basalt, which was also regarded as remarkable, remembering that the enclosing rock was once molten lava erupted at 1000–1200°C (about 1800–2200°F).
Tiny portions of the same piece of fossil wood encased in the basalt in the drill core were sent for radiocarbon (C) analyses to two reputable laboratories—Geochron Laboratories in Cambridge, Boston (USA), and the Antares Mass Spectrometry laboratory at the Australian Nuclear Science and Technology Organisation (ANSTO), Lucas Heights near Sydney (Australia).
Neither laboratory was told exactly where the samples came from to ensure that there would be no resultant bias.
Pieces of the basalt samples from the outcrop and the drill core were also sent to analytical laboratories, for major, minor, and trace element analyses to establish the character of these rocks, but mainly for radioactive ‘dating’ analyses.
Potassium-argon (K-Ar) ‘dating’ was performed on the two outcrop samples by the AMDEL laboratory in Adelaide (Australia), while one of the two outcrop samples and two drill core samples, one being in contact with the fossil wood, were ‘dated’ by Geochron Laboratories. When subsequently questioned regarding the limits of the analytical method for the radiocarbon and any possibility of contamination, staff at both laboratories (Ph. scientists) were readily insistent that the results, with one exception, C results (last column in Table 1), consistent with the carbon being organic carbon from wood, and indicating no possibility of contamination.The K-A ages provide another strong correlation of the odd phenomenon observed by the RATE Project.That there was evidently a burst of much accelerated radioactive decay at some point in the past. G'day Andrew, Congratulations on a very interesting article.The local geological context makes the basalt flow approximately ‘30 million years old’, in keeping with other basalt flows in the region all regarded as of Tertiary age (in the conventional terminology).Since the tree trunks were entombed in the basalt lava, the wood is thus supposedly at least 30 million years old.Also, what looked like the tree roots were found in the siltstone below the basalt, suggesting the trees when alive were rooted into the siltstone and thus growing on a land surface that was then covered by basalt lava.Tags: Adult Dating, affair dating, sex dating
