RHYOLITE | Rhyolite is an aphanitic felsic rock which forms during eruptions of thick, viscous magma. Often containing phenocrysts of felsic minerals with only slightly higher crystallization temperatures than the feldspar and quartz that forms rhyolite GREAT FOR GEOLOGY CLASSROOMS | Ideal for identification & classification exercises. The evolved chemistry of the rock makes it lightweight relative to other igneous rocks- a good identifier for classification 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 Rhyolite SpecimenSingle Sample, 1"Rhyolite is an aphanitic felsic rock which forms during eruptions of thick, viscous magma. Often containing phenocrysts of felsic minerals with only slightly higher crystallization temperatures than the feldspar and quartz that forms rhyolite. Ideal for teaching students about rounding and sorting, as well as for identification & classification exercises. The evolved chemistry of the rock makes it lightweight relative to other igneous rocks- a good identifier for classification.While each specimen will vary slightly in shape, size and color, it will measure approximately 1" in length. Each is individually packaged, labeled & barcoded for easy identification and storage.Selected & Processed by a Geologist.Each and every specimen is selected and hand processed by an actual geologist, ensuring that each sample exhibits defining features. Rocks and minerals are sourced from a variety of locations around the world and are processed by hand in Victor, NY.Technical SupportAlways feel free to reach out to our team of scientists and geologists for additional information, or to assist you with any questions regarding our rock and mineral samples.
