Rock and Mineral Specimens and Collections
Eisco™ Dolomite Mineral Specimen
Dolomite is similar to calcite but includes magnesium in its chemistry, which makes it a more robust and stable mineral.
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.
Eisco™ White Quartzite, Metamorphic Rock Specimen - Approx. 1 Inch - 10 Pack
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™ Coarse White Marble, Metamorphic Rock Specimen - Approx. 3 Inch
For use in classroom activities to ascertain differences between metamorphic rocks and their provenance. EISCO Coarse White Marble Specimen (Metamorphic Rock) is formed from limestone. High-pressure, low-heat alteration leads to massive crystalline rock.
Eisco™ Raw Fluorite, Mineral Specimen - Hand Sample - Approx. 3 Inch
Fluorite Mineral Specimen is used in classroom identification lab exercises and for study of uncommon 4-plane cleavage pattern.
Eisco™ Metamorphic Rocks Kit
For study of foliation and alteration of these metamorphic rocks to understand the immense heat and pressure needed to form them. The Metamorphic Rocks Kit contains 12 specimens measuring approx. 3 cm (1 in.) and specimen key.
Eisco™ Scoria Specimen
Scoria forms when spatter from bubbly mafic lava cools quickly.
Eisco™ Sulfur Mineral Specimen
Sulfur Mineral Specimen ideal for mineral identification exercises, due to its instantly recognizable physical properties.
Eisco™ Phyllite Specimen
Phyllite Specimen for demonstrations of metamorphic properties, such as glossy sheen and dense, foliated minerals.
Eisco™ Serpentinite Metamorphic Rock Specimen
When clay- and aluminum-rich rock is altered by water from geothermal systems, serpentinite is liable to form. Serpentinite is often found in low-grade metamorphic areas and is formed when clay and aluminum rich rock is altered by water from geothermal systems.
Eisco™ Andesite Specimen
Andesite Specimen for introduction to igneous rock classification and identifying minerals within igneous rocks.
Eisco™ Labradorite Mineral Specimen
Labradorite is a variety of plagioclase feldspar, an intermediate between anorthite and albite.
Eisco™ Limestone Specimen
Limestone Specimen is made up of mostly calcium carbonate and organic material.
Eisco™ Halite Mineral Specimen
Halite Mineral Specimen ideal for teaching students about cleavage planes and how evaporate deposits form.
Eisco™ Carbonaceous Shale Specimen
Carbonaceous Shale Specimen is formed from cementation and lithification of very small grains of rock, commonly mud or clay.
