MORDENITE FROM GLEN BRITTLE, ISLE OF SKYE

摘要

The occurrence of the comparatively uncommon zeolite mordenite is described from vesicles in a basaltic lava within the Skye Lava Group at Glen Brittle, Isle of Skye. The form of the mineral here differs from that at its sole previously recorded location on the island at Sgurr nam Boc. At Glen Brittle mordenite is locally intergrown with quartz. Laumontite, prehnite, chabazite, calcite and saponite are also present in very small amounts.
