100 rocksarranged stratigraphicallyhandpiece: 90x120 mmin collectors' boxeswooden case includedCharacteristic rocks from all types of geological formations reveal the evolutionary history of our planet. They document periods of increased volcanic or tectonic activity, extensive ocean areas or large land masses, climatic changes and how life evolved on earth.The hand specimens are labeled with the exact name, age and locality. A film is placed over each label to prevent scratching. A numbering system allows easy identification of the rocks if they are misplaced. The rocks in this collection are supplied in system-bloc collection boxes, which are arranged in a wooden case. A detailed list of contents is included with each collection.The photo serves as an example illustration, you will receive a collection of equivalent quality.

100 thin sectionsaccompanying the collections of 100 stones P16 (small stones)  / P17 (bigger stones)in wooden caseSize: 28 x 48 mm. The slides are 28 x 48 mm in size and fitted with cover glasses. They are numbered and provided with adhesive labels, which give the exact description as well as the age and the place of discovery. They are delivered in a grooved thin-section case. A detailed list of contents is enclosed with every collection.A detailed contents list with locality and exact name is included with each collection, there are thin sections of stones included, like:stones and thin sections from Igneous Rocks, such as plutonic rocks (f.e. Pegmatite, Biotite Granite, Muscovite Granite, Rapakiwi Granit, Luxullianite, Granodioriote, Diorites, Syenites, Monzonites, Plagioclase Rocks, like Gabbro, Foid Rocks, Ultramafic rocks) and of course Volcanic Rocks (f.e. Rhyolites, like Obsidian, Dacites, Trachytes, Latites, Basaltes, Phonolotes, Selbergites, Tephrites, Basanites, Foides and Pyroclatites)Also you’ll find Sedimentary Rock thin sections from Clastic Rocks (f.e. Psephites, Psammites, Pelites), Chemical Sedimentary Rocks (Precipitate Rocks, like Travertine & Dolomite and Saline Deposits, like Anhydrite) and Organic Deposits (f.e. Limestones, Siliceous Rocks, Phosphates and Coals)And also there are metamorphic rock thin sections: Thermal Metamorphism (f.e. Burnt clay, Chiastolite schist), Regional Metamorphism (f.e. Gneisses, Granulites, Micaschists, Phyllites)Suitable thin sections are available for almost all geological collections.

100 rocks.handpieces: 60 x 90 mmin collection boxeswithout wooden caseParticularly high-contrast rocks from worldwide localities were selected, which impressively demonstrate the diversity of formation in the metamorphic, sedimentary and magmatic areas: 46 igneous, 34 sedimentary and 20 metamorphic rocks. (Minor changes are possible!)Our range of systematic rock collections offers everything from small to large teaching collections to provide a basis for both beginner and advanced petrographic courses. The samples are divided into igneous, sedimentary and metamorphic rocks and within these groups are arranged according to modern systematics. The specimens are labeled with the exact name, age and locality. A film is placed over each label to prevent scratching. The stones are numbered so that they can be easily reassigned if one is misplaced.The rocks of this collection are supplied in system-bloc collection boxes, a detailed list of contents is included with each collection.The photo serves as an example illustration, you will receive a collection of equivalent quality.
