Beschreibung

Nobody can escape the fascination of the mineral world, because each mineral is a unique specimen and evokes admiration due to its form, colour, shape and distinct features. Worldwide, more than 4600 different minerals were identified. Since 2008, the most beautiful of them have found their permanent home in TERRA MINERALIA in the university town of Freiberg. In 90 selected steps this e-book leads the mineralogical journey that began in Europe to Asia and Australia.

Preface

Five centuries ago the great scholar of mining and metallurgy Georgius Agricola said: "The soul's most pleasing food is observing nature". Particularly with regard to the unique treasures the fascinating realm of minerals has to offer, this is true even today. So far, more than 4,250 different kinds of minerals have been found, most of them unsurpassable in their crystalline shape, unusual colours and aesthetic perfection. Collecting and preserving these precious objects of "frozen earth history" is not only fascinating but immensely useful if, as in the present case, these arduously acquired minerals are made available to the public and therefore to general education.

For the Swiss scholar Dr. Erika Pohl-Ströher it was a matter of course to donate her unique collection of minerals collected with great enthusiasm from all parts of the world to the oldest mining academy of the world, the TU Bergakademie Freiberg, as a foundation in 2004. With this, Freiberg's geosciences have now an excellent scientific base.

This collection called "terra mineralia" is located and presented in Freudenstein Castle, the history of which dates back to the 12th century. The castle has a place in history particularly as the birthplace of Moritz, Duke of Saxony, and as the residence of Henry the Pious. First, however, extensive restauration works were necessary, the results of which can be seen in courageous architectural solutions. Today, Freudenstein Castle offers a fitting home to both the Freiberg mining archives and the collection of minerals.

"Terra mineralia" is "a mineralogical journey round the world" and bound to the credo of dealing with the wonders of nature and exploring the overwhelming beauty of the European, Asian, Australian, African and American continents. This credo is not only the leitmotiv for the collection but also for the four parts of this photoalbum which presents selected stages of the "Pohl-Ströher Minerals Foundation". It starts with Europe and embarks on a mineral journey from Germany through many European countries up to the Ukraine and Russia. For this journey we offer a heartfelt "Good Luck".

Spodumene (Kunzite) on Quartz

This magnificent, crystal clear kunzite crystal, which grew on a fine-crystal quartz, is fascinating. Such beautiful, perfectly developed samples occur rather rarely. Considering the colour, people are spontaneously reminded of fresh lavender. In 1879, the American gemstone expert George F. Kunz discovered this mineral in Connecticut/USA and the specimen was called after him. Chemically, this mineral, which belongs to the group of spodumene, is a lithium alumosilicate and the yellow-green variety – hiddenite – as well.

Tourmaline

Tourmaline is the most colourful gemstone at all. Therefore, there are many varieties: achroite is colourless, the brown dravite, the blue indigolite, rubellite is pink or red, schorl is black, siberite is lilac – red or violet – blue and verdelite is green. In addition, the canary tourmaline is yellow. The Singhalese ‘tura mali
