link.springer.com/article/10.1007/BF01160288Strontian-loparite is recognized at Sarambi and Chiriguelo, Paraguay and at Salitre I, Brazil as an accessory mineral in rheomorphic sanidine-aegirine-nepheline dikes associated with carbonatite plugs. Strontio-chevkinite is recognized only at Sarambi in the same rheomorphic fenites hosting Strontian-loparite, with lamprophyllite as an additional strontium-bearing mineral.

Structurally similar to hezuolinite; however, the O(1), O(2) and O(3) sites typical for hezuolinite are split into six sites in rengeite; also the Si(1)-O(7)-Si(2) angle is more bent in rengeite.
