Sample of teschenite from Poland
Teschenite is a type of igneous rock . Its name is derived from the town of Český Těšín , where it was discovered. The term crinanite has previously been used as a synonym for teschenite,[1] however there have been attempts to standardize and stop its use.[2] [3] Rocks related to teschenite are referred to as rocks of the teschenite association .[4]
Geological composition
[ edit ]
Teschenite is a mixture of several minerals including titan -augite , analcime , various hornblendes , labradorite and in lesser quantities olivine .[5] [6] Teschenite also has subtypes such as lugarite .[7]
History
[ edit ]
Teschenite was first described and given a name by Ludwig Hohenegger [cs ] in 1861.[8]
In 1866 teschenite occurrences with higher concentrations of magnesium were defined as picrite by Erich von Tschermak .[5]
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 ] [9]
In 1918 the same name was declared official by František Slavík .[10] [11] [12]
Location of occurrence
[ edit ]
Teschenite has been found in Scotland , Portugal , the Caucasus Mountains , Siberia , Kenya , Myanmar , Taiwan , Australia and New Zealand .[6] [13]
In the Czech Republic , teschenite is primarily found in the volcanic region of the Beskids which stretch from the borders of Moravia to regions east of Český Těšín .[10] Specific documented deposits are in Tichá , in the basin of the Ostravice river, in the Řepiště municipality and in a quarry near Žermanice Reservoir .[10] [6] [14] [15] [16] Historically, olivine-rich teschenite has also been mined in an old quarry in Straník .[17]
