  Abstract:  Type localities in geology include those geographic locations where the origin and provenance of key geologic terms (such as mineral and rock names, fossil taxon names, formation names, stratotypes etc.) and their material counterparts were identified and described for the first time. They are parts of the classical geological literature, hence of the universal and national geological cultural heritage. Type localities are abundant in the Carpathian-Pannonian Region and particularly in Romania (Papp, 2002; Anonymus, 2009). This presentation focuses on rock and mineral type localities in Romania. Rock names originating from Romanian type localities include “dacite”, “banatite” and “ditroite”, of which only dacite is universally validated and widely used by geologists, many of whom might not be aware of its origin. Unlike other magmatic rock names, “dacite” has a very accurately identifiable locality where it was first described, so that the history of the term can be precisely tracked back to its origin. “Dacite”, coined by Guido Stache (in Hauer and Stache, 1863) from the name of the Roman province Dacia (today part of Romania), was given to felsic volcanic rocks containing plagioclase phenocrysts, to be distinguished from trachyte with K-feldspar phenocrysts. The type locality of “dacite” is the Gizella quarry near Poieni (Kissebes in Hungarian) where the rock crops out and was identified and originally described.

Key words: type locality, rock, mineral, geosite, cultural heritage
