"It is a mineral of secondary origin, and occurs with other zeolites in the amygdaloidal cavities of weathered mafic volcanic rocks. Associated minerals include quartz, apophyllite, babingtonite, heulandite, stilbite and other zeolites. It was first described from Kaiserstuhl in Baden in 1813. Fine divergent groups of prismatic crystals are found in the basalt of Berufjord near Djupivogr in Iceland and in the Deccan Traps near Pune in India; hence the synonym poonahlite for this species. Other occurrences include Riverside County, California; Skye, Scotland and Santa Catarina, Brazil."@es . "Scolecite"@es . .
