Raw Carbonaceous Shale Sedimentary Rock Specimen - Approx. 1" CARBONACEOUS SHALE | Shale is formed from the cementation and lithification of very small grains of rock, commonly mud or clay. The black color of the rock indicates an organic-rich composition GREAT FOR GEOLOGY CLASSROOMS | Black shale can contain trace amounts of oil, and is studied heavily for this reason. Shale is useful in sedimentary rock identification exercises due to its recognizable fissile habit GEOLOGIST SELECTED | Each specimen is selected and hand processed by an actual geologist, ensuring each sample exhibits defining features LOCALLY PROCESSED | Our rock and mineral samples are sourced from a variety of locations around the world and are processed in Victor, NY INDIVIDUALLY PACKAGED & LABELED | Each specimen sample is packaged in a transparent bag, and is labeled & barcoded for easy identification

CHALCOPYRITE | From the same family as fool's gold, Chalcopyrite is a yellow crystalline mineral consisting of a sulfide of copper and iron. It is the principal ore of copper formed in hydrothermal veins GREAT FOR GEOLOGY CLASSROOMS | Chalcopyrite's formation exhibits fracture and has a brassy luster which make it an excellent tool for studying economic geology, and is great for us in comparative identification exercises GEOLOGIST SELECTED | Each specimen is selected and hand processed by an actual geologist, ensuring each sample exhibits defining features LOCALLY PROCESSED | Our rock and mineral samples are sourced from a variety of locations around the world and are processed in Victor, NY INDIVIDUALLY PACKAGED & LABELED | Each specimen sample is packaged in a transparent bag, and is labeled & barcoded for easy identification

Raw Chlorite Metamorphic Mineral Specimen - Approx. 1" CHLORITE | Chlorite is a metamorphic mineral that has undergone light alteration. During metasomatism, phyllosilicate minerals may become hydrated and form chlorite. The greener color and near-soapy feel of chlorite distinguishes it from other phyllosilicates at a glance, and the presence of water distinguishes it chemically GREAT FOR GEOLOGY CLASSROOMS | This sample is ideal for lessons on metamorphism, mineral alteration, as well as general identification and classification exercises GEOLOGIST SELECTED | Each specimen is selected and hand processed by an actual geologist, ensuring each sample exhibits defining features LOCALLY PROCESSED | Our rock and mineral samples are sourced from a variety of locations around the world and are processed in Victor, NY INDIVIDUALLY PACKAGED & LABELED | Each specimen sample is packaged in a transparent bag, and is labeled & barcoded for easy identification

CONGLOMERATE | The large clasts in conglomerate indicate that the pieces of rock underwent a large amount of rolling, bouncing, and other weathering to become round. This implies deposition in a river far from the source of the clasts GREAT FOR GEOLOGY CLASSROOMS | Ideal for teaching students about rounding and sorting, as well as for identification & classification exercises GEOLOGIST SELECTED | Each specimen is selected and hand processed by an actual geologist, ensuring each sample exhibits defining features LOCALLY PROCESSED | Our rock and mineral samples are sourced from a variety of locations around the world and are processed in Victor, NY INDIVIDUALLY PACKAGED & LABELED | Each specimen sample is packaged in a transparent bag, and is labeled & barcoded for easy identification

Raw Diorite Igneous Rock Specimen - Approx. 1" DIORITE | The minerals within diorite can be readily identified due to their large size, and by comparing the relative abundance of each mineral, a rough chemical makeup can be obtained GREAT FOR GEOLOGY CLASSROOMS | Ideal for identification & classification exercises. Diorite straddles the line between mafic and felsic rock chemistry, making it ideal for lessons in bulk chemistry GEOLOGIST SELECTED | Each specimen is selected and hand processed by an actual geologist, ensuring each sample exhibits defining features LOCALLY PROCESSED | Our rock and mineral samples are sourced from a variety of locations around the world and are processed in Victor, NY INDIVIDUALLY PACKAGED & LABELED | Each specimen sample is packaged in a transparent bag, and is labeled & barcoded for easy identification

DOLOMITE | Though similar to calcite, the inclusion of magnesium in the chemistry of Dolomite makes it a more robust & stable mineral GREAT FOR GEOLOGY CLASSROOMS | Ideal for learning about physical and chemical properties. Great for having students compare with calcite - a challenging but beneficial exercise GEOLOGIST SELECTED | Each specimen is selected and hand processed by an actual geologist, ensuring each sample exhibits defining features LOCALLY PROCESSED | Our rock and mineral samples are sourced from a variety of locations around the world and are processed in Victor, NY INDIVIDUALLY PACKAGED & LABELED | Each specimen sample is packaged in a transparent bag, and is labeled & barcoded for easy identification

Raw Fluorite Mineral Specimen - Hand Sample - Approx. 3" FLUORITE | Fluorite can be transparent or come in a variety of colors, such as purple, green & blue. Fluorite is a common mineral in both carbonate and hydrothermal rocks GREAT FOR GEOLOGY CLASSROOMS | Fluorite is perfect for hands on lessons in hardness, as well as the fickle method of identifying minerals by color. An excellent example for lessons in cleavage, as it is one of the few minerals that has four perfect planes of cleavage GEOLOGIST SELECTED | Each specimen is selected and hand processed by an actual geologist, ensuring each sample exhibits defining features LOCALLY PROCESSED | Our rock and mineral samples are sourced from a variety of locations around the world and are processed in Victor, NY INDIVIDUALLY PACKAGED & LABELED | Each specimen sample is packaged in a transparent bag, and is labeled & barcoded for easy identification

FOSSILIFEROUS LIMESTONE | This rock formed at the bottom of a marine environment through the compaction of deceased organic matter in a clay or silt cement GREAT FOR GEOLOGY CLASSROOMS | Ideal for identification & classification exercises, for studying fossils within whole rocks and sedimentary rocks GEOLOGIST SELECTED | Each specimen is selected and hand processed by an actual geologist, ensuring each sample exhibits defining features LOCALLY PROCESSED | Our rock and mineral samples are sourced from a variety of locations around the world and are processed in Victor, NY INDIVIDUALLY PACKAGED & LABELED | Each specimen sample is packaged in a transparent bag, and is labeled & barcoded for easy identification
