|The Zillertal is very well known for its Szepter- and Window-Amthyst and its Hematit-roses (Eisenrosen), which can be found in the Mörchnerkaar and the Saurüssel. The Amthyst quite frequently do not have the most intense violett colors, but they impress more by their shape. Here we show a Sezepter of about 5 cm hight. In fact, it appears that there was first a nomal Quarz, which was then overgrown by a doubly terminated pale Amethyst. What makes this specimen special are the fine hairs of Rutil and two blades of Brookite, which can be seen in the upper part of the crystal.|
Zillertal in Tyrol (Austria) is famous for its Almandine
garnets, which have long been mined both as cutting rough as well as
The crystals usually do not grow to the size of those found in the Ötztal, but can reach several centimeters. The one on the left is a typical example from the Hornkees. I have been collecting there myself and believe me: the real challenge is to clean the specimen up and remove the schist around the garnets. Crystals are up to ~ 2 cm here. The right one was found also in the Zillertal, on the Berliner Spitze. It ahs a particularly shiny red and is 35 mm in diameter
| Iron-rose (Eisenrose,
Hematit, ~1.5 cm) grown on a crystal of Adularia (~4 cm). |
Self collected at the Mörchner-Kar in Zillertal, Tyrol in the mid 1990ies.
Epidote from the Knappenwand in Salzburg, which is certainly one of the most important sites for this mineral (crystal is ~4 cm high).
Obtained from www.irocks.com, (from the former Wein Collection).
The Knappenwand was discovered in 1865 as a major source of Epidote. For a long time it has been mined by the Natural History Museum of Vienna for scientific purposes. Recently, the old mine has been re-activated and restored as a show mine, which can be visted during the summer month. More information here.
with elongated Almandine Crystals |
from the Zillertal, Tyrol, Austria.
Almandines in the Zillertal formed as a metamorphic mineral: when the host rock was pulled down into the earth it heated up and was put under pressure. The rock did not melt, but some of its constituents became instable and set free certain chemical elementd. These diffused through the solid rock and formed the Almandine garnets. Because it is known the Almandine requires a certain temperature for its growth it can be used as kind of a geo-thermometer. The Zillertal is very famous for its garnets: they have been mined here for several hunderet years, in part for jewellery and in part as grinding materaial, due its hardness.
