Chemical composition of ferrierite

Abstract Ferrierite specimens from localities at Altoona, Washington; Silver Mountain, Alpine County, California; and Pinaus Lake, Monte Lake, and Francois Lake, British Columbia, have been analyzed by microprobe methods. These new analyses are combined with available data to delineate the compositional range for this zeolite. The broad compositional range of ferrierite indicates that it can crystallize from solutions with a wide variety of alkali and alkaline earth cations, none of which are essential to the zeolite. If present, Mg ions are fractionated into the zeolite. Ferrierite crystallizes in response to high silica activities. However, to account for the range in silica contents, the a810, must be coupled with other variables, such as temperature or aH,o, in order to prevent crystallization of other high silica zeolites
