Page 37 - ... which is probably scolecite were observed in association with natrolite. The chemical relationship between natrolite and scolecite is somewhat similar to that between chabazite and gmelinite, but the group appears to present an example of a different type of solid solutions, namely, that in which the two components do not form a continuous series of mixed crystals, mutual solubility being limited and the end members being of distinct crystallographic forms.28 Most of the specimens are plainly...
