[Aqualist] seeking carbonate

[Anthony Dosseto]

Hi,

Does anyone have a small quantity of carbonate (chunk or powder) they would be willing to share? Ideally it would need to be 50-100 ka old and with a homogenous composition.
I need a carbonate standard for U-Th by laser ablation and don't know of anything commercially available (that's old so 230Th>0). So I'm trying to setup my own.
Any help would be welcome... I'll pay you back in free U-Th ages!!
Thanks,

Tony
