Capsule Geology

The Zymoetz River Zeolite occurence comprises the zeolitized portion of the upper member of the Telkwa Formation (Upper Triassic to Middle Jurassic Hazelton Group).

The upper member contains 190 metres of red zeolitized lithic lapilli and vitric ash tuffs and 115 metres of zeolitized quartz and feldspar-rich (15 and 50 per cent respectively) crystal ash tuff. In some of the layers, laumontite is the main component.
