Abstract
Volcanic rocks occurring in Ladinian (?) marls, interstratified with limestone (Solčava beds), at Grohat Alpine Meadow and Lipni plaz, Mt. Raduha, are shallow intrusives bodies with porphyric structure, and basaltic andesitic, acid andesitic and dacitic composition. Abundance of major oxides and trace elements in the studied rocks is similar to those observed in the Tertiary Smrekovec volcanic rocks suggesting contemporaneous formation and close genetic relationship.

Summary
Marls with intercalations of thin limestone beds of Ladinian (?) age (Sol~ava beds) at Lipni plaz (fig. 1, loc. 1), Grohat Alpine Meadow (fig. 1, loc. 2) and Je‘ (fig. 1, loc. 3), north-western flanks of Mt. Stanko Buser (personal communication) believes the presented volcanics are Ladinian sills and dykes, similar to those found in the Jezersko area (Buser & Cajhen 1977) Another possibility is, that volcanic rocks are of Tertiary age and are genetically related to Smrekovec volcanic complex. The samples from Mt. Grohat and Lipni plaz are very similar according to petrological characteristics, and they closely resemble the Smrekovec coherent volcanic rocks ( Kralj , 1996). Grohat and Lipni plaz are very similar according to petrological characteristics, and they closely resemble the Smrekovec coherent volcanic rocks ( Kralj , 1996) They are plagioclase-magnetite vitrophyres which consists of glassy groundmass, phenocrysts, microphenocrysts and microlites (Plate 1 – Fig. 3, 4).
