Scientific controversy concerning radioisotopic dating
However, the data presented were taken in conditions of laboratory vacuum and actual diffusion rates in field conditions are known to be considerably lower, by as much as a factor of one thousand or more.
The RATE researchers claim to have meticulously accounted for all crystallographic features.
Isochron Discordances In the chapter on isochron discordances, the authors present a large amount of data that date rocks in the range of hundreds of millions of years.
The isochron method relies on selecting minerals from different regions of a particular rock formation.
Funding was provided by the ICR (0,000) and by more than one million dollars of donations.
This chapter also provides guidance for carrying out creation science research.
However, the diffusion rate of noble gases in minerals is so complex both theoretically and experimentally that helium concentrations are not considered by geochronologists to be reliable for any dating implications.
143-146) is part of a scientific examination of RATE and Radiometric Dating that includes a response from RATE and more. Chaffin, ed., (Waco, TX: Institute for Creation Research, 2005). A nontechnical version of this book, authored by Donald De Young, and a video documentary have also been prepared. in solid-state physics at the University of Illinois at Urbana-Champaign.The first chapter is an introduction and provides an overview of the RATE program.An entire chapter is devoted to presenting the technical data in each of these four topics.Helium Diffusion in Zircons The authors argue that by extrapolating data on the rate of helium diffusion in minerals, the high concentration of helium in zircons can only be explained by a young earth.
