Footnotes

A – denotes accessory minerals. Colours under the microscope should be noted both under PPL and XPL.

Extinction angle and Interference Colours (Birofingence) is always observed under XPL. Some minerals such as dolomite verses calcite are difficult to identify without a hand sample. These images are NOT a replacement for hands on lab experience. If you find any errors, please contact me.

Colour balance issues; since it was extremely hard to calibrate the digital camera to reflect the true colours and due to various other factors, the colours in these images may not be perfectly accurate. For example, the Calcite in PPL suppose to look clear.
