M05. Forsterite Marble
 >View Microscope
Fact sheet
Description: 

This forsterite marble comes from the Glenelg region, Inverness-shire, Scotland. Minerals present are calcite, dolomite, olivine (forsterite) and minor clinopyroxene (diopside), mica (phlogopite) and chlorite, with secondary serpentine in bands crossing and surrounding olivine. The lower part of the section has been stained with alizarin dye, making calcite pink but not affecting dolomite. The huge olivine grain here has a calcite inclusion which itself has  inclusions of dolomite. This dolomite was probably exsolved from the calcite during cooling
