A pineapple from French Polynesia
This very distinctive zeolite facies combines thick thomsonite lamellae with very fine needles of the same species. The whole is deposited on a bed of very fine, completely transparent analcime crystals revealing the greenish colour of the basaltic lava matrix.
It was found in 2018 in Tahiti, inside a vacuolar basalt boulder carried by the Papenoo River.
