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™ 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™ 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™ 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™ 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™ Carbonaceous Shale Specimen
Carbonaceous Shale Specimen is formed from cementation and lithification of very small grains of rock, commonly mud or clay.
Eisco™ Black Hematite Mineral Specimen
Hematite specimen that is ideal for demonstrations in mineral physical properties.
Eisco™ Hematite Mineral Specimen
This specular variety of hematite takes the form of tiny, sparkling iron oxide crystals.
Eisco™ Chlorite Mineral Specimen
Chlorite is a metamorphic mineral that has undergone light alteration.
Eisco™ Fluorite Mineral Specimen
Fluorite Mineral Specimen is used in classroom identification lab exercises and for study of uncommon 4-plane cleavage pattern.
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™ Oligoclase Mineral Specimen
Oligoclase is a feldspar with high levels of sodium.
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™ Limestone Specimen
Limestone Specimen is made up of mostly calcium carbonate and organic material.
