Peridotite Slide

Stunning peridotite thin section exhibiting the bright and beautiful colours of olivine and pyroxene punctuated by relatively abundant plagioclase. Peridotite is a dense, coarse grained, ultramafic igneous rock consisting largely of olivine and pyroxene. These slides supplement the hand specimens nicely and are useful for interpreting the crystallisation history of the rock. Peridotite is derived from the Earth's mantle either as blocks & fragments or from crystallisation from magma generated in the mantle. We collected this material from Finland and each section is made to 30 microns thickness. The glass is 46 x 27 mm in size, supplied in a protective card sleeve with a label, ideal for microscopy.
