Zeolite minerals from intermediate volcanic rocks of Tokaj Mts., NE-Hungary

In recent years zeolite minerals have been found in large number in the Tokaj Mts. The examinations show that the parageneses in the intermediate rocks differ from those known in the acid rocks or pyroclastites of the area. The dominating minerals are mordenite, heulandite and stellerite. As a rarit...

Description
Summary:In recent years zeolite minerals have been found in large number in the Tokaj Mts. The examinations show that the parageneses in the intermediate rocks differ from those known in the acid rocks or pyroclastites of the area. The dominating minerals are mordenite, heulandite and stellerite. As a rarity two species the hungarian occurence of which was unknown up to now were found in an outcrop near Regec. In this paper the author gives the description of the parageneses, the species identified, discusses the formation of the assemblages and crystal morphology referring to instrumental examinations.
