Description

Details

Mica schist thin section microscope slide exhibiting an alignment of platy minerals within this popular metamorphic rock. The alignment of platy minerals, in this case biotite and muscovite mica produces a texture known as foliation. Foliation occurs as a result of directed pressure which can either rotate platy minerals or recrystallise minerals in the direction of preferred orientation, or both. These rock specimens are from the Dalradian series, a complicated group of various metamorphic rocks which are dated to the Pre-Cambrian period and is present in both Scotland and Ireland. Each section is made to 30 microns thickness and the glass is 46 x 27 mm in size with a cover slip. Supplied in a protective card sleeve with a label, ideal for microscopy and educational purposes.
