Greetings in the Lord's name!
Thanks for your kind words regarding the helium in zircon diffusion experiments. We are grateful to the Lord for the way He has led and guided that project, and indeed all of the RATE research. Of course, we appreciate very much your pioneering work on the helium in zircons, and the radiohalos, which we have acknowledged and have merely built upon.
Please understand at the outset that we do not desire to generate controversy or ill-will toward you with respect to our different views on the origin and formation of granites, and the Po radiohalos in them. We cannot but go where we strongly believe the evidence, both field and laboratory, points, but always in dependence on wisdom and guidance from the Lord through His Word and by prayer.
Bob, you know as well as we do that granites do not contain fossils. Indeed, we would not expect them to contain fossils, because, as granites are igneous rocks, any organic material in the source rocks that melted would have been incinerated. Furthermore, you have carefully read the November Acts and Facts and Impact #353, so you know that I did not claim or write there that we had found and sampled granites containing fossils. Therefore, why do you insist that we provide you with the location details for "fossiliferous granites"? That's not "borrowing the language of Impact #353," but imputing to us something we did not write or claim.
Of course, we can provide you with the precise location details (even GPS coordinates in most instances) of every granite sample we have collected, and you are more than welcome to those details. However, that is not the real issue, is it? You don't agree with our claim that many granites were produced during the Flood by the melting of Flood-deposited, fossiliferous sediments to form molten magmas that then intruded into, and thus cooled surrounded by, other Flood-deposited sediments. According to your model for granite formation, and ours, we should not expect to find fossils in granites, but a real issue here is whether there are fossils in the rocks hosting granites.
There is not the space here for a long technical discussion of all the detailed evidences. Nor does it seem appropriate, given that you must surely be already aware of all the many evidences as presented in the voluminous literature on the subject of granites. However, it would seem you have rejected those impeccable evidences because they have been compiled and presented, in the main, by uniformitarian geologists, and because they conflict with your views based on the Po radiohalos. Nevertheless, you state in your letter that you are seeking to follow the truth, and that you are still learning. Bob, as your friends and your Christian brothers, we have to say, unfortunately very bluntly, that it is wrong for you to go on denying and rejecting the many impeccable observational evidences, that are not tainted with uniformitarianism, but which unequivocally show that many granites were formed from magmas derived by the melting of sediments at temperatures and pressures that destroyed contained fossils. So that you know we are genuine and not generating some smokescreen, let us summarize (all too briefly) the main lines of evidences that convince us (and most other creationist geologists):
Bob, when we found Po radiohalos alongside U radiohalos in the same biotite flakes in the Cooma Granodiorite we had to rethink what the radiohalos are telling us. We fully agree with you that the Po radiohalos formed exceedingly rapidly, so this granodiorite must have formed rapidly during the Flood. This is exciting evidence that granites intrude and cool rapidly (within days). It is also thus evidence that the U radiohalos formed rapidly, so U decay had to have been accelerated during the Flood year. Your ground-breaking work on Po radiohalos is not being "trashed," but lifted to an exciting new level that still demolishes the uniformitarian timescale. We would also point out that your responses have not been brushed aside and ignored, for they were cited in the comprehensive discussions of radiohalos in chapter 8 of our book, Radioisotopes and the Age of the Earth, published in 2000.
As your friend, Bob, please, you must rethink your position carefully before the Lord. It's time to stop willfully ignoring the evidences for the magmatic origin of granites and the implications. You are wrong to expect us, or anyone else, to show you "fossil-bearing granites." That's nonsense, and you know it! We would welcome you joining us in showing compromising Christians and unbelievers alike that these evidences in God's world powerfully support what God's Word has always plainly taught.
Regards and best wishes,
Yours sincerely in Christ,
