This is a collection of videos and gifs of thin section slides made by Geosec over the last 10 years or so. There is no order or theme, produced as and when I had time, and something interesting presented itself. These have been made as a test of what could be done, mainly for my own amusement, but I hope you will fine them interesting.

This is a clip of an Olivine Norite, a type of gabbro with orthopyroxene instead of the usual clinopyroxene, collected from neat Huntly in Aberdeenshire.
The view is of most of the slide, about 3cm x 2cm. The whole width of the slide is one pyroxene crystal (orange) with inclusions of plagioclase and olivine. The latter shows edge alteration to serpentine minerals.
