Radioactive dating of rock samples is a method of legal dating age in nebraska
Here is one example of an isochron, based on measurements of basaltic meteorites (in this case the resulting date is 4.4 billion years) [Basaltic1981, pg. Skeptics of old-earth geology make great hay of these examples.For example, creationist writer Henry Morris [Morris2000, pg.
Chronological sequence is all that is really required.The woody internal structure was clearly evident, thus the samples were not the remains of roots that had grown into this weathered rock from trees on the present land surface.When sampled, the fossil wood readily splintered, diagnostic of it still being ‘woody’ in spite of its impregnation with iron minerals during fossilisation.Figure 3(b) Closer view of the quarry face of the south wall showing the oxidized limestone of the top of the Marlstone Rock Bed which is quarried as ‘Hornton Brown’ building stone. During two visits to the Hornton Quarries, it was established that fossil wood occurs alongside ammonite and belemnite index fossils (see aside below) in the ‘Hornton Stone’, the oxidized silty top of the Marlstone Rock Bed.
The ammonite recovered in the quarries is Many such belemnite fossils had been found during quarrying operations (Figure 6).
The slope of the line determines the date, and the closeness of fit is a measure of the statistical reliability of the resulting date.
