"Uranium-thorium-lead dating is not subject to some of these problem."
I think you will find that Uranium salts are surprisingly soluble - and if you have ever seen people whose drinking water is delivered by lead piping in soft water regions, then you will know that lead and its salts are also very soluble.
"In a vacuum each method has problems, thats why we have refereed journals."
Refereed journals are only as good as the basic dogmas which authors and referees all hold in common. Every so often a widely held scientific dogma is trashed and everything is up for grabs again - such is the nature of science when minds are not closed too tightly.
While the system of peer review is probably the only workable one, it does have in-built bias toward self-selection, and marginalisation of those whose work challenges any prevailing "orthodoxy".
At the moment geology is still trapped in a XVIIth century time warp when Alexander Stenon formulated his theories of sedimentology. These are now being blown apart, and a similar shift will soon occur in this discipline just as Einstein moved the world on from Newtonian mechanics and Quantum theory moved the world on from relativity.
All current geological dating methods will be thrown into serious doubt. Have you come across Guy Berthault's (University of Denver, Colorado) research yet?
