The abundance and wide horizontal distribution of the glendonites on certain horizons of the Upper Marine Series of the Permo-Carboniferous system of New South Wales, points to the probability that the original mineral was formed of some commonly occurring elements.

The term "glendonite" does not refer to a mineral, but to a class of pseudomorphs.
