Dear Huiming,

I have loaded samples of microspherule beds from the Barite Syncline  
for triple oxygen analysis. Maybe you already did this? I dont  
expect  to find a meteorite signature but who knows?

I had to shift the 253 over to O2 analysis because of problems with  
the 252 so I'm temporarily out of the S-isotope business. The  
meteorite game for oxygen analysis is very active: 4 abstracts  
submitted on Tuesday to the LPSC.

Very Best,

Doug
