Eisco™ Oligoclase Mineral Specimen
Oligoclase is a feldspar with high levels of sodium.
Eisco™ Garnet Mineral Specimen
Garnet forms under intense heat and pressure conditions, making it a common mineral in mountainous terranes.
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™ 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™ 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™ Scoria Specimen
Scoria forms when spatter from bubbly mafic lava cools quickly.
Eisco™ Gypsum Rock Specimen, 3cm
Gypsum is a sulfate mineral formed as the byproduct of evaporating saltwater. When this mineral becomes lithified, it forms rock gypsum, a sedimentary rock. These 3cm samples are great for use as classroom specimens or as a part of a small rock collection.
Eisco™ Chorite Mineral Specimen
Chlorite is a metamorphic mineral that has undergone light alteration. During metasomatism, phyllosilicate minerals may become hydrated and form chlorite.
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™ Raw Chlorite, Metamorphic Mineral Specimen - Approx. 3 Inch
Chlorite is a metamorphic mineral that has undergone light alteration. During metasomatism, phyllosilicate minerals may become hydrated and form chlorite.
Eisco™ Biotite Gneiss Specimen
Biotite Gneiss is high-grade metamorphic rock formed from other rocks undergoing alteration from intense heat and pressure.
Eisco™ Mica Garnet Schist Specimen
Mica Garnet Schist Specimen for use in lessons on metamorphic rock properties, classification, and identification.
Eisco™ Labradorite Mineral Specimen
Labradorite is a variety of plagioclase feldspar, an intermediate between anorthite and albite.
