K/T tektite page

The bubble in the middle of the tektite. It did not know where to go, so it stayed in the middle. That's typical behaviour for a bubble in zero gravity! Those bubbles are inherited through various stages of diagenetic alteration of these spherules around the Gulf of Mexico

broken spherule with internal bubbles. The brown material is goyazite SrAl3(PO4)2(OH)5·(H2O)

Enlargement, showing the shiny(=very smooth) interior of the cavities. The white material is anhydrite
