12 Pack - Raw Andesite Igneous Rock Specimens - Approx. 1"ANDESITE | Andesite features abundant phenocrysts in a fine grained matrix, and offers a great demonstration of igneous porphyry GREAT FOR GEOLOGY CLASSROOMS | Ideal for identification & classification exercises. Andesite is an excellent example of porphyry in igneous rocks. The fine-grained felsic matrix contains larger, identifiable hornblende crystals, indicating two different rates of cooling. This set of six samples is excellent for group study and examination 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

12 Pack - Raw Anthracite Coal Metamorphic Rock Specimens - Approx. 1"ANTHRACITE COAL | Anthracite coal is bright and reflective, indicative of the intense heat and pressure required to form it. Anthracite coal often has a favorable purity ratio, containing mostly organic material and relatively few impurities GREAT FOR GEOLOGY CLASSROOMS | Ideal for identification & classification exercises. Allows students can get a close look at a material that powers the world. This set of six samples is excellent for group study and examination 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

12 Pack - Raw Carbonaceous Shale Sedimentary Rock Specimens - 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. This set of six samples is excellent for group study and examination 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 LABELED PACKAGING | Set is packaged in a transparent bag, and is labeled & barcoded for easy identification

12 Pack - Raw Chlorite Metamorphic Mineral Specimens - 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. This set of six samples is excellent for group study and examination 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 LABELED PACKAGING | Set is packaged in a transparent bag, and is labeled & barcoded for easy identification

12 Pack - Raw Dolostone Sedimentary Rocks - Approx. 1"DOLOSTONE | Composed primarily of carbonate material, dolostone is a more stalwart rock than its chemical cousin, limestone. It is often mined for construction and infrastructure purposes, being used heavily in industry as concrete or in the home as countertops GREAT FOR GEOLOGY CLASSROOMS | Ideal for identification & classification exercises. Can be used to teach students about sedimentary petrology, chemical sedimentary rocks, and industrial geology. This set of six samples is excellent for group study and examination 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 LABELED PACKAGING | Set is packaged in a transparent bag, and is labeled & barcoded for easy identification

12 Pack - Raw Garnet Schist Metamorphic Rock Specimens - Approx. 1"GARNET SCHIST | A metamorphic rock that has undergone moderate levels of alteration, schist is good for demonstrating the effect of metamorphism on various minerals GREAT FOR GEOLOGY CLASSROOMS | Ideal for identification & classification exercises. Schist is also a great rock for demonstrating foliation, making it useful for lessons on metamorphic rock properties. This set of six samples is excellent for group study and examination 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 Rochester, NY INDIVIDUALLY PACKAGED & LABELED | Each specimen sample is packaged in a transparent bag, and is labeled & barcoded for easy identification

12 Pack - Raw Gypsum Mineral Specimens - Approx. 1"GYPSUM | A sulfate mineral that often forms from evaporating lakes in what is known as an evaporite deposit. Crystals grow into soft, wide sheets, but gypsum is also commonly found filling veins and fractures in other rocks GREAT FOR GEOLOGY CLASSROOMS | Gypsum is one of the standards on the Mohs hardness scale, and its similar appearance to other minerals makes it useful in identification exercises. This set of six samples is excellent for group study and examination 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 LABELED PACKAGING | Set is packaged in a transparent bag, and is labeled & barcoded for easy identification

12 Pack - Raw Hornblende Amphibole Mineral Specimens - Approx. 1"HORNBLENDE | Hornblende is part of a group of minerals known as amphiboles. These minerals are chemically and structurally similar to pyroxenes, but include water in their atomic structure GREAT FOR GEOLOGY CLASSROOMS | Ideal for identification & classification exercises. Useful when studying both igneous and metamorphic rocks, as well as when learning the process behind mineral identification.
