Beautiful minerals of the GDR The Ministry of Posts and Telecommunications of the GDR publishes a series with six multicolored special postage stamps on which beautiful minerals from the German Democratic Republic are depicted. Minerals of the GDR Many types and varieties of minerals have been described in the scientific literature for the first time in the Ore Mountains, the Thuringian Forest and the Harz. A large number of minerals occur in the territory of the German Democratic Republic in excellent quality and special beauty. For these reasons, minerals of our homeland can be found in all the major collections in the world. As in recent years again and again interesting findings of minerals were discovered in the GDR, the issue of a stamp series with mineral motifs is of particular relevance. The minerals displayed on the stamps were all found on the territory of the GDR today. The steps are stored in the mineralogical collection of the Geosciences section of the Bergakademie Freiberg. 15 Pfennig value: Galena (galena) PbS from Neudorf near Harzgerode, Harz (No. 4016) Galena is by far the most common and important lead ore. His color is lead gray. Galenite has a strong metallic shine, especially on fresh fracture surfaces, which always show a right-angled splitability. The crystals of galena prefer dicey forms. For the brand image was a level of about 120 x 80 mm as a template. The crystals are up to 50 mm in size and are combinations of shapes of cube and octahedron. In addition to the gray galena, there are smaller crystals of siderite FeCO3. The illustrated minerals give a little insight into the richness and beauty of the mineral deposits of the GDR. The exhibitions of the mineralogical collections at the Bergakademie in Freiberg (Saxony) and the Humboldt University in Berlin provide a much broader overview of this area of nature.
