87Sr is stable. It does not change back int 87Rb or or into any other isotope of Sr.

85Sr is not used in Rb-Sr isochron dating.

Here is an abstract on cosmogenic 40k but its split between two pages

Irrelevant. Not terrestrial.

You said the following was an excellent table http://en.wikipedia.org/wiki.......rontium

Well look at the daughter isotopes of 87Sr

There are no daughter isotopes of Sr-87 which comes from Rb-87 because that Sr-87 is stable. Jebus you're stupid. Sr m means metastable, but is not formed from Rb-87, so the fact that it decays has no measurable effect on Rb-Sr isochron dating.

I notice that you avoided Jon's so called excellent link, which provides two daughter isotopes
