Augite is a common rock-forming pyroxene mineral that forms as magma is cooling. It is an imperative sample for lessons on Bowen's reaction series Augite's perpendicular planes of cleavages make it an excellent tool for studying 2-plane, 90° cleavage Each specimen is selected and hand…
-
Formed from limestone, this high pressure, low heat alteration leads to a large crystalline rock. Heavily mined for architecture, marble is also used for buildings and furniture While denser than limestone, marble is still effervesce in acid, making this metamorphic rock useful in identification…
-
Pack of 12 Pegmatite samples approximately 1" (3cm) in size Igneous rock containing a large variety of crystal sizes Perfect size for use in classroom identification labs and exercises, correlates well to Next Generation Science Standards Evidence Statements Pegmatite indicates two different…
-
Gabbro is formed within magma chambers, deep within the earth. The chambers hold iron-rich rock melt, too heavy to reach the surface. As the melt cools, olivine and plagioclase feldspar forms A great example of phaneritic mafic rock. Useful for exercises in identification and classification of…
-
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. Useful in the classroom for lessons on metamorphic…
-
Pumice is formed from the frothy lava that a volcanic explosion creates. As the frothy lava cools, it hardens as a light weight rock that is filled with small gas bubbles. Because this rock is so porous and light, it can actually float on water Perfect for demonstrating the effect of vesicles on…
-
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. While this characteristic is normally reserved for igneous rocks, travertine is unique in that it forms as a result of rapidly…
-
Coal is formed within anoxic environments from compressed organic matter, and a worldwide source of fuel. Its vitreous sheen makes Bituminous Coal easy to distinguish from other coals and sedimentary rocks Allows students to get a close up look at a material that powers the world. Excellent for…
-
Magnetite forms as an accessory mineral from an igneous melt. As it cools, the iron in its atomic structure becomes magnetized Magnetite's attraction to magnets and distinctive black streak make it an excellent tool for identification exercises. This set of twelve samples is excellent for group…
-
Apatite is one of the few common phosphate minerals. While often found as an accessory mineral in igneous rock, it is also found as concretions or detrital clasts in sedimentary rocks With a standard Mohs hardness of 5, and it's relatively uncommon crystal habit, Apatite is excellent for…
-
Pack of 12 Augen gneiss samples approximately 1" (3cm) in size Ideal for students learning about differential stresses and foliation in metamorphic rocks Perfect size for use in classroom identification labs and exercises, correlates well to Next Generation Science Standards Evidence Statements …
-
Through the process of metasomatism, hot fluid infiltrates the atomic structure of other silicate minerals, altering them to form talc. Talc is at the bottom of the Mohs scale of hardness, and has a distinct soapy feel Ideal for identification & classification exercises. A great example for…
-
Pack of 12 Oligoclase samples approximately 1" (3cm) in size Standard hardness of 6, exhibits two planes of cleavage Perfect size for use in classroom identification labs and exercises, correlates well to Next Generation Science Standards Evidence Statements Feldspar with high levels of sodium …
-
Slate is the result of the compression of shale, but is denser and retains the fissile properties, making for an interesting exercise when distinguishing between the two rocks Ideal for exercises in metamorphic rock identification due to its recognizable platy foliation. This set of twelve samples…
-
Pack of 12 Albite samples approximately 1" (3cm) in size Used as a hardness standard of 6, and exhibits two planes of cleavage Perfect size for use in classroom identification labs and exercises, correlates well to Next Generation Science Standards Evidence Statements Great samples for use in…
-
A fun introduction to the world of geology through sedimentary rocks! Sedimentary rocks are formed by the deposition and compression of particles of other rocks and minerals. Each Tech Cut specimen is selected and hand processed, ensuring each sample exhibits defining features. Set includes…
-
A fun introduction to the world of geology through rocks and minerals. Set includes twelve different rocks and minerals - Crystal Quartz, Basalt, Breccia, Biotite Gneiss, Fluorite, Granite, Conglomerate, Marble, Apatite, Scoria, Sandstone, and Slate. While each specimen will vary in shape and…
-

-
Obsidian, also known as volcanic glass, forms from lava that cools almost immediately upon eruption, usually into water Obsidian shares many physical properties with its major chemical component, quartz, despite looking dissimilar - great for classification exercises. This set of twelve samples is…
-
Though similar to calcite, the inclusion of magnesium in the chemistry of Dolomite makes it a more robust & stable mineral Ideal for learning about physical and chemical properties. Great for having students compare with calcite - a challenging but beneficial exercise. This set of twelve samples…

-
The large clasts in conglomerate indicate that the pieces of rock underwent a large amount of rolling, bouncing, and other weathering to become round. This implies deposition in a river far from the source of the clasts Ideal for teaching students about rounding and sorting, as well as for…
