Paralammerite was approved in 2009 and to date (March 2025) has been reported only from the type locality.

Localities

At the type locality, the Tolbachik Volcanic field, Milkovsky District, Kamchatka Krai, Russia, paralammerite has been found as rare small splinter-shaped grains less than 0.15 mm in size formed by post-eruption fumarolic reactions at 400 to 650°C in the active volcano. Associated minerals include alarsite, euchlorine, lammerite and piypite (Mindat).
