MAGNETITE | Magnetite forms as an accessory mineral from an igneous melt. As it cools, the iron in its atomic structure becomes magnetized GREAT F...

MICROCLINE | One of the most common minerals in the earth's crust, feldspar has a variety of physical properties that make it a quintessential min...

MILKY QUARTZ | One of the most abundant minerals on Earth. The tightly packed framework of silica tetrahedral that makes up this mineral gives it ...

MUSCOVITE MICA | Muscovite mica is a mineral that forms from cooling magma. It forms in thin sheets that are individually weak, but comprehensivel...

Raw Obsidian SpecimenSingle Sample, 1" OBSIDIAN | Obsidian, also known as volcanic glass, forms from lava that cools almost immediately upon eru...

OLIVINE | Much of the earth's surface is covered in oceanic crust, of which olivine is a major component. With the highest crystallization tempera...

PORPHYRITIC GRANITE | Granite forms slowly in shallow or evolved magma chambers, and is also commonly found as magmatic intrusions in the crust. T...

PYRITE | Pyrite forms as hot water flows through fractures in subsurface rock. This deposition method allows pyrite to replace other minerals or f...

QUARTZ | One of the most abundant minerals on Earth. The tightly packed framework of silica tetrahedral that makes up this mineral gives it a high...

RED SANDSTONE | Sandstone is made up of well-sorted and well-rounded grains of quartz. This indicates that the clasts in the rocks have traveled a...

SCORIA | Scoria forms as spatter from bubbly, mafic lava is thrown into the air and cooled quickly. The crystallization happens so quickly that la...

SOAPSTONE | Through the process of metasomatism, hot fluid infiltrates the atomic structure of other silicate minerals, altering them to form soap...
