Do you have an idea of how much of an effect the CRE exposure might have on Pd-Ag or Hf-W ages based on the magnitude of your Pt CRE offsets?
For the most exposed sample measured here, we could expect resolvable differences to nucleosynthetic signatures in the Pd and Ru systems. For Hf-W isochrons, GCR would most likely lead to increased scatter of the data depending on the Ta/W ratios, etc, of the different fractions.

Hi Alison, which ordinary chondrite shows the relatively large GCR effect? How well do these data correlate with exposure ages?
The ordinary chondrite with the largest effect is a H5 chondrite, with an average exposure age for H5s. The data correlate well with exposure age, given that the size of the meteoroid and shielding depth are also important.
