Rock and Mineral Specimens and Collections
Eisco™ Raw Andesite, Igneous Rock Specimen - Approx. 3 Inch
Andesite Specimen for introduction to igneous rock classification and identifying minerals within igneous rocks.
Eisco™ Green Slate Metamorphic Rock Specimen
Green 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™ Albite Specimen
Albite is a variety of plagioclase feldspar that is rich in sodium. With a glossy sheen, 2 planes of cleavage, and a standard hardness of 6, this mineral is a classic specimen for lessons in mineralogy and petrology. Useful when trying to distinguish from other feldspars.
Eisco™ Pumice Specimen
Pumice is formed quickly during volcanic eruptions around pockets of air within lava.
Eisco™ Mica Schist Specimen
Mica Schist Specimen for use in lessons on metamorphic rock properties, classification, and identification.
Eisco™ Chalcopyrite Mineral Specimen
From the same family as fool's gold, Chalcopyrite is a yellow crystalline mineral consisting of a sulfide of copper and iron. It's the principal ore of copper formed in hydrothermal veins.
Eisco™ Argillaceous Shale Specimen
Argillaceous Shale Specimen is formed from cementation and lithification of very small grains of rock, commonly mud or clay.
Eisco™ Siltstone Specimen
Siltstone Specimen is a clastic rock made up of small, nearly microscopic grains of silt.
Eisco™ Syenite Igneous Rock Specimen
Syenite is a variety of felsic igneous rock heavily composed of feldspar. Though formed similarly to granite, the higher aluminum content of syenite indicates a more evolved magma.
Eisco™ Milky Quartz Mineral Specimen
Milky Quartz Mineral Specimen has a tightly packed framework and hardness of 7, complete lack of cleavage planes, and distinct euhedral crystal habit.
Eisco™ Porphyritic Granite Specimen
Porphyritic Granite Specimen is a must-have sample when discussing rock types, rock cycle, formation, classification, and identification of igneous rocks.
Eisco™ Mohs Hardness Kit
This Tech Cut Mohs Hardness Kit includes 8 specimens with streak plates.
Eisco™ Andesite Specimen
Andesite Specimen for introduction to igneous rock classification and identifying minerals within igneous rocks.
Eisco™ Phyllite Specimen
Phyllite Specimen for demonstrations of metamorphic properties, such as glossy sheen and dense, foliated minerals.
Eisco™ Arkose Sandstone Specimen (Sedimentary Rock)
Arkose Sandstone is clastic sedimentary rock made up of angular, poorly-sorted sand-size grains.
