This is the only part of the book I would question because Baumgardner believes the evidence for these events in the past is overwhelming.
There are probably myriads of evolutionary/uniformitarian assumptions that have gone into these Earth model deductions.
Towards the end of his article, he describes the very interesting correlation between high heat flow at the Earth’s surface and the measured radioactivity—on an outcrop by outcrop level!
Steve Austin describes the three methods of radioactive dating: 1) the model age, 2) the whole rock isochron, and 3) the mineral isochron.
He breaks new ground by categorizing four types of radioactive discordance.
This book is the group’s first major report of its research and findings. It will be difficult reading for laymen and most scientists not versed in the methods of radioactive dating.
Chaffin ICR, El Cajon, CA & CRS, St Joseph, MI, 2000 by Michael Oard A group of young-Earth researchers called RATE (Radioisotopes and the Age of The Earth) are investigating radioactive dating methods and developing alternative young-Earth explanations.
