![]() Most commonly formed as a devitrification product of silicic volcanic glass from tuffs. Also occurs in cavities in rhyolites, andesites, and basalts. |
![]() Valid Species (Pre-IMA) 1923 |
![]() Decomposed basalt at a high point on ridge running east from Hoodoo Mountain, Wyoming, USA. From an off-shore borehole, Japan (Ogihara and Iijima, 1990). Link to MinDat.org Location Data. |
![]() The name reflects its inclined extinction and supposed similarity in composition to "ptilolite" (mordenite). K modifier added by zeolite nomenclatrue committee. |
