Rock and Mineral Specimens and Collections
Eisco™ Mica Schist Specimen
Mica Schist Specimen for use in lessons on metamorphic rock properties, classification, and identification.
Eisco™ Augite (Pyroxene Mineral) Specimen
Augite (Pyroxene Mineral) Specimen suitable for use in classroom identification lab exercises and for study on 2-plane, 90° cleavage.
Eisco™ Labradorite Sedimentary Rock Specimen
Labradorite is a variety of plagioclase feldspar, intermediate between anorthite and albite. Notable about this species of feldspar is its potential for iridescence.
Eisco™ Oligoclase Mineral Specimen
Oligoclase is a feldspar with high levels of sodium.
Eisco™ Loadstone Mineral Specimen
Loadstone is a naturally magnetized mineral that creates it's own magnetic field and can pick up small metal objects. Iron particles cover its surface.
Eisco™ Red Slate Metamorphic Rock Specimen
Red slate is a very lightly metamorphosed and well-foliated specimen. It can be distinguished from it's parent rock (Shale) by the difference in pitch when struck.
Eisco™ Garnet Mineral Specimen
Garnet forms under intense heat and pressure conditions, making it a common mineral in mountainous terranes.
Eisco™ Dolostone Sedimentary Rock Specimen
Dolostone is a lithified form of dolomite. 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.
Eisco™ Oolitic Limestone Sedimentary Rock Specimen
Oolitic limestone is a carbonate rock formed from the cementation of thousands of ooids, tiny nodules formed from the accumulation of carbonate material around a nucleus. Oolitic limestone forms in reef or lagoon environments.
Eisco™ Raw Phyllite, Metamorphic Rock Specimen - Approx. 3 Inch
Phyllite Specimen for demonstrations of metamorphic properties, such as glossy sheen and dense, foliated minerals.
Eisco™ White Quartzite, Metamorphic Rock Specimen - Hand Sample - Approx. 3 Inch
Quartzite is formed from sandstone that has been tightly compressed to the point where the clasts have recrystallized to form a new rock. This formation mechanism, coupled the inherent strength of quartz, makes quartzite a very durable rock.
Eisco™ Raw Fossiliferous Limestone, Sedimentary Rock Specimen - Approx. 3 Inch
Fossiliferous Limestone Specimen for sedimentary rock identification and studying fossils within whole rocks.
Eisco™ Streak Plates for Rocks and Specimens
The off-white unglazed porcelain of these streak plates show a mineral's color in powder form, or to identify the mineral content of a rock.
Eisco™ Sedimentary Rocks Kit
For use in identification of depositional history of sedimentary rocks based on their grain size and composition. The Sedimentary Rocks Kit contains 12 specimens and specimen key.
Eisco™ Sphalerite Mineral Specimen
Sphalerite is a sulfide often mined for its zinc content and is typically associated with other sulfide minerals such as pyrite and chalcopyrite.
