Rock and Mineral Specimens and Collections
Eisco™ Metamorphic 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™ Basalt Specimen
Basalt is formed quickly from an iron-rich magma and exhibits a dark color and small crystal size.
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™ 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™ Fluorite Mineral Specimen
Fluorite Mineral Specimen is used in classroom identification lab exercises and for study of uncommon 4-plane cleavage pattern.
Eisco™ Garnet Mineral Specimen
Garnet forms under intense heat and pressure conditions, making it a common mineral in mountainous terranes.
Eisco™ Fine White Marble Specimen
Fine White Marble Specimen for use in classroom activities to ascertain differences between metamorphic rocks and their provenance.
Eisco™ Travertine Sedimentary Rock Specimen
Travertine is a carbonate rock formed from gushing hot springs. The airy, porous material indicates an abundance of air bubbles moving through the rock as it solidified. Travertine is unique in that it forms as a result of rapidly dropping pH levels.
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™ White Quartzite Metamorphic Rock Specimen
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™ Hematite Mineral Specimen
This specular variety of hematite takes the form of tiny, sparkling iron oxide crystals.
Eisco™ Oligoclase Mineral Specimen
Oligoclase is a feldspar with high levels of sodium.
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™ Gypsum Mineral Specimen
Gypsum Mineral Specimen ideal for use in study of cleavage and fracture as example of imperfect cleavage planes.
Eisco™ Biotite Gneiss Specimen
Biotite Gneiss is high-grade metamorphic rock formed from other rocks undergoing alteration from intense heat and pressure.
