Abstract
The tetranatrolite-paranatrolite transformation has remained a key problem in understanding the paragenesis of zeolites in the natrolite family. It is accepted that when paranatrolite, approximate formula Na(16-x)Ca(x)Al(16+x)Si(24-x)O(80)(.)24H(2)O, is removed from an aqueous environment and exposed to the atmosphere, it loses water and transforms to tetranatrolite, Na(16-x)Ca(x)Al(16+x)Si(24-x)O(80)(.)nH(2)O (n
