Granite forms slowly in shallow or evolved magma chambers, and is also commonly found as magmatic intrusions in the crust. The large crystals are indicative of a slow cooling rate, and make mineral identification simple A must-have sample when discussing rock types, the rock cycle, and the...

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 lessons...

Pack of 12 Diorite samples approximately 1" (3cm) in size Presence of both mafic and felsic minerals make diorite a perfect example of intermediate igneous chemistry Perfect size for use in classroom identification labs and exercises, correlates well to Next Generation Science Standards Evidence...

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...

A metamorphic rock that has undergone moderate levels of alteration, schist is good for demonstrating the effect of metamorphism on various minerals Ideal for identification & classification exercises. Schist is great rock for demonstrating foliation & metamorphic rock properties. This set of six...

The Mohs hardness test is a simple and useful way to identify minerals and assess their relative hardness. This kit includes everything you need to explore using Mohs hardness test to identify minerals The kit includes 1" pieces of nine different minerals, including Talc, Gypsum, Calcite, Fluorite,...

Pack of 12 Argillaceous shale samples approximately 1" (3cm) in size Small clast size indicates deposition in a low-energy environment such as a shallow lake or slow-moving river Perfect size for use in classroom identification labs and exercises, correlates well to Next Generation Science Standards...

Calcite is made up of calcium carbonate. It can grow into rocks, animal shells, chalk, & translucent, rhombic minerals Being one of just a few minerals that is effervesce in acid, Calcite is great for demonstrating chemical reactions. This universally useful mineral can also be used to demonstrate...

Sandstone is made up of well-sorted and well-rounded grains of quartz. This indicates that the clasts in the rocks have traveled a long distance from their source and were heavily eroded along the way. This sample is red due to the inclusion of iron in the chemical structure of the rock. This sample...

One of the most abundant minerals on Earth. The tightly packed framework of silica tetrahedral that makes up this mineral gives it a high hardness of 7, a lack of cleavage planes, and a distinct euhedral crystal habit A must-have mineral for any specimen collection. Milky Quartz is useful during...

Pack of 12 Arkose samples approximately 1" (3cm) in size Small, angular grains indicate deposition in an ephemeral river system near to the clast source Perfect size for use in classroom identification labs and exercises, correlates well to Next Generation Science Standards Evidence Statements Great...

From the same family as fool's gold, Chalcopyrite is a yellow crystalline mineral consisting of a sulfide of copper and iron. It is the principal ore of copper formed in hydrothermal veins Chalcopyrite's formation exhibits fracture and has a brassy luster which make it an excellent tool for studying...

Pack of 12 Limonite samples approximately 1" (3cm) in size Rusty color indicative of ongoing oxidation Perfect size for use in classroom identification labs and exercises, correlates well to Next Generation Science Standards Evidence Statements Also known as goethite Specimens come in clear, labeled...

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...

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 periods...

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...

One of the most abundant minerals on Earth. The tightly packed framework of silica tetrahedral that makes up this mineral gives it a high hardness of 7, a lack of cleavage planes, and a distinct euhedral crystal habit A must-have mineral for any specimen collection. Quartz is useful during lessons...

Set of 6 3-D manipulatives for demonstrating normal faulting, reverse (thrust) faulting and horizontal faulting. Set is provided with an access code to download interactive Teacher and Student Guides, videos, geoinformation data sets, and other resource information.

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...

Pack of 12 Dolostone samples approximately 1" (3cm) in size Raw carbonate rock deposited and lithified out of solution Perfect size for use in classroom identification labs and exercises, correlates well to Next Generation Science Standards Evidence Statements Often used as an ingredient in cement...

Andesite features abundant phenocrysts in a fine grained matrix, and offers a great demonstration of igneous porphyry Ideal for identification & classification exercises. Andesite is an excellent example of porphyry in igneous rocks. The fine-grained felsic matrix contains larger, identifiable...

The massive, gray variety of limestone is often found deposited in marine environments. It is made up of organic material, primarily calcium carbonate Excellent for demonstrating the tendency of calcium carbonate to effervesce in acid, and is perfect for identification and classification exercises....

Oolitic limestone is a carbonate rock formed from the cementation of thousands of ooids. Ooids are tiny nodules formed from the accumulation of carbonate material around a nucleus. When cemented together and lithified, these ooids can form rock. Oolitic limestone forms in reef or lagoon...

A fun way to explore the variety of techniques that geologists use to identify rocks and minerals Test mineral hardness, streak color, magnetic properties, appearance, and effervescence to identify different minerals and mineral content within rock specimens Includes seven essential tools - reusable...
