Teschenite
Type of igneous rock / From Wikipedia, the free encyclopedia
Teschenite is a type of igneous rock, which was first described and named by Ludwig Hohenegger [cs] in 1861.[1] Its name is derived from the town of Český Těšín, where it was discovered. Until 1892 the name in use for the rock was tchesenit, which is derived from the German name for Český Těšín. The name teschenite (těšínit in Czech) was first used by mineralogist Josef Klvaňa [cs], and in 1918 the same name was declared official by František Slavík.[2][3][4][5]
The name crinanite has previously been used as a synonym for teschenite,[6] however there have been attempts to standardize and stop its use.[7][8]
