Collection: 20 sedimentary rocks (90x120 mm)

20 thin sectionsaccompanying the collections of sedimentary stones P51 (small stones)  / P54 (bigger stones)in wooden caseThe slides are 28 x 48 mm and have cover slips. They are numbered and have adhesive labels indicating the exact name as well as the age and locality of discovery. They are supplied in a slotted thin section case. A detailed contents list with locality and exact name is included with each collection, there are thin sections of stones included, like:Conglomerates and breccias – Psephites (f.e. Quartz conglomerate, Breccia), Sandstones – Psammites (f.e. Sea sand, Sandstone, Quartzite), Silt & Clay Rocks – Pelites (f.e. Clay, Oil Slate, Loess), Carbonate Rocks (f.e. limestones, Chalk), Sedimentary Rocks of special depositional environments (f.e. Salt Rocks, like Anhydrite, Siliceous Rocks, like Flint, Sedimentary Phosphate Rocks, like Phosphorite, Residual Rocks, like Bauxite and Coal)

20 igneous rocksSpecimens: 60x90 mmsorted in System-bloc collection boxes, including a wooden caseOur range of systematic rock collections provides the foundation for both introductory and advanced petrography courses.This collection includes:magmatic rocks (e.g., pegmatite, granite, granodiorite, syenite, plagioclasites,foid rocks, mafic rocks) andvolcanic rocks (e.g., rhyolite, trachyte, latite,basalts, porphyrites, selbergite, nephelinite, and pyroclastic rocks)The specimens are labeled with tags providing precise identification, age, and locality. A System-bloc protective film covers each label to prevent scratching and stains.The rocks are numbered so that they can be easily re-identified if a specimen is removed.This collection is delivered in System-bloc collection boxes, which are arranged inside a wooden case. A detailed list of contents is included with each collection.Our collections are handcrafted in-house.Please note that rocks are natural products and no two pieces ever look exactly alike.Due to technical limitations, colors in product photos may vary slightly from those of the original piece.Our images serve as a reference; when you purchase a collection, you will receive one of equivalent quality.
