I see that Mike Fisher has added some material to his site to help date geochronology at http://www.newgeology.us/presentation30.html

I read most of it and it seems to have rather credible reasoning. So I'll see if I can gather most of the elements of his theory as well as those from Cardona's theory at http://www.thunderbolts.info/forum/phpBB3/viewtopic.php?f=10&t=3824 and parts of Walter Brown's theory, especially on mammoths, the Grand Canyon and radioactive decay at http://creationscience.com/onlinebook , and possibly some of Jno Cook's material at http://saturniancosmology.org .
