A lot going on with this specimen. Silver thin ilmenite plates formed first and were then coated with phillipsite-Na and chabazite-Na crystals. You can see the ilmenite where there are broken areas. Then later, a few thomsonite puffballs have formed. Ex Margaret Brown Collection. Width of view 6mm. Stack of 35 images.
