Rock and Mineral Specimens and Collections
Eisco™ Pumice Specimen
Pumice is formed quickly during volcanic eruptions around pockets of air within lava.
Eisco™ Greywacke Sedimentary Rock Specimen
Graywacke is a sedimentary rock composed of large, angular clasts within a fine-grained clay matrix. Formed during underwater avalanches, these rocks are often found on distal ocean shelves.
Eisco™ Rhyolite Specimen
Rhyolite Specimen is aphanitic felsic rock, formed during eruptions of thick, viscous magma.
Eisco™ Raw Fossiliferous Limestone, Sedimentary Rock Specimen - Approx. 3 Inch
Fossiliferous Limestone Specimen for sedimentary rock identification and studying fossils within whole rocks.
Eisco™ Raw Andesite, Igneous Rock Specimen - Approx. 3 Inch
Andesite Specimen for introduction to igneous rock classification and identifying minerals within igneous rocks.
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™ Mohs Hardness Kit
This Tech Cut Mohs Hardness Kit includes 8 specimens with streak plates.
Eisco™ Lodestone Mineral Specimen
A naturally magnetized mineral that creates its own magnetic field and can pick up small metal objects.
Eisco™ Milky Quartz Mineral Specimen
Milky Quartz Mineral Specimen has a tightly packed framework and hardness of 7, complete lack of cleavage planes, and distinct euhedral crystal habit.
Eisco™ Syenite Igneous Rock Specimen
Syenite is a variety of felsic igneous rock heavily composed of feldspar. Though formed similarly to granite, the higher aluminum content of syenite indicates a more evolved magma.
Eisco™ Red Slate Metamorphic Rock Specimen
Red slate is a very lightly metamorphosed and well-foliated specimen. It can be distinguished from it's parent rock (Shale) by the difference in pitch when struck.
Eisco™ Green Slate Metamorphic Rock Specimen
Green slate is a very lightly metamorphosed and well-foliated specimen. It can be distinguished from it's parent rock (Shale) by the difference in pitch when struck.
Eisco™ Coquina Sedimentary Rock Specimen
Composed of bone and shell fragments, coquina is nearly 100% fossil matter. Held together by a carbonate cement, this skeletal mass forms in low-energy environments such as lagoons and reefs.
AquaPhoenix Scientific Biotite Mica
