Rock and Mineral Specimens and Collections
Eisco™ Fossiliferous Limestone Specimen
Fossiliferous Limestone Specimen for sedimentary rock identification and studying fossils within whole rocks.
Eisco™ Anthracite Coal Specimen
Anthracite Coal is formed in anoxic environments from compressed organic matter, and is used worldwide as fuel source.
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™ Hematite Mineral Specimen
This specular variety of hematite takes the form of tiny, sparkling iron oxide crystals.
Eisco™ Chert Mineral Specimen
Sometimes referred to as flint, Chert is a sedimentary rock rich in silica.
Eisco™ Igneous Rocks Kit with Storage Box and ID Card
A fun introduction to the world of geology through a 12-piece rock kit. Each Tech Cut specimen is selected and hand processed by an actual geologist, ensuring each sample exhibits defining features.
Eisco™ Conglomerate Specimen
Conglomerate Specimen has large clasts that indicate that pieces of rock underwent large amount of rolling, bouncing, and other weathering to become round.
Eisco™ Apatite Specimen
Apatite is a common phosphate mineral often found as an accessory mineral in igneous rocks or as concretions or detrital clasts in sedimentary rocks. A standard Mohs hardness of 5 and a relatively uncommon crystal habit.
Eisco™ Pyrite Mineral Specimen
Pyrite Mineral Specimen has a shiny metallic luster and bright brassy color, making it an ideal addition to mineral collections or classroom exercises.
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 Quartz, Mineral Specimen - Approx. 3 Inch
Quartz mineral specimen for use in classroom identification labs and exercises.
Eisco™ Hornfels Specimen
Hornfels forms in narrow band between an igneous intrusion and surrounding rock.
Eisco™ Gabbro Specimen
Gabbro forms when iron-rich magma too heavy to reach surface cools slowly over time.
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™ Oligoclase Mineral Specimen
Oligoclase is a feldspar with high levels of sodium.
