Dirty bot chats that are good - Contamination dating radiocarbon
The complex was formed by explosive volcanism from multiple coalescing eruptive centers, episodic intrusion of alkaline igneous rocks (ranging from phonolite to lamprophyre), development of funnel-shaped breccia pipes, and repeated eruption and subsidence cycles.A two-phased mineralizing event closely followed emplacement of the volcanic complex.
Furthermore, a cored exploration hole drilled in 2003 intersected a small piece of carbonized fossil wood in tuff and rock fragments of the Cripple Creek Breccia at a vertical depth of 3,079 feet beneath the surface under the mine.
The postulated mechanism responsible for burying this fossil wood so deeply within this volcanic complex is the subsidence that followed many violent volcanic eruptions.
However, such is the rapid decay of radiocarbon (C), with a half-life of 5,730 years, that even after only 250,000 years there should be no detectable radiocarbon left.
Thus, organic materials supposedly millions of years old should not contain any radiocarbon whatsoever.
The laboratory reported that the dried residue consisted of needles with a carbon content normal for organic material.
A very short chlorite bleach treatment then had to be used because the sample rapidly oxidized.
has similarly reported measurable radiocarbon in ancient organic materials, well above the threshold of the accelerator mass spectrometry (AMS) analytical technology used, including ten samples of US coals spanning 45-300 million years of the conventional timescale for the geologic record.
Meticulous laboratory procedures rule out the possibility that this measured radiocarbon is due to contamination, so it must instead be intrinsic to these ancient organic materials.
After being carefully packaged and labeled, this sample was submitted with the required documentation to Professor Roelf Beukens at the Iso Trace Radiocarbon Laboratory at the University of Toronto in Ontario, Canada.Tags: Adult Dating, affair dating, sex dating
