Name(s) in local language(s):
Pirešiški masiv, Pirešica, Slovenija
The Pirešica massif was formed by underwater eruptions in Triassic era - starting in Illyric substage of upper Anisium and continuing throughout Ladinium stage; it is surrounded by younger Tertiary sediments on the north, north-east and eastern side, which are dated from Oligocene to Miocene. The western, south-western and southern contact is with Triassic dolomites, there is a quarry of building stone and gravel.
Volcanic rocks are mostly granitoid-like in composition - ranging from quartz keratophyr to quartz porphyry. Petrologically interesting is the Pirešica dacite, which is carrying analcime (due to laumontite-analcime pseudomorphosis; confirmed using X-ray powder diffraction).
