  • Interestingly, very well formed zeolites are sometimes found in very old Grenville openings that have been subjected to low temperature hydrothermal alteration. Here is a good example. The poor pyroxene crystals that form the matrix for very well formed stilbite and heulandite cryustals. The stilbite crystals are present as classic, divergent clusters with an orange-brown colouration. The heulandites are present as well formed crystals with pearly luster on the pinacoids so typical of heulandite. Very nice example!
