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).
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.
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.
When miners were sinking a ventilation shaft for the new Crinum Coal Mine in Central Queensland in 1993 (see map below) they unearthed a rare find.
