quartz under the microscope in thin section

#MineralMonday playing chess with quartz!

This is my favorite quartz microstructure. It is called 'reticular grains', quartz deformed at high temperature with a tendency of grain boundaries to encounter at 90° angles #hotstuff

Microphoto of an anthophyllite amphibole grain (yellow), stretched and partly replaced by antigorite.

A stretched amphibole grain (grunerite - yellow). The voids are filled by fibers of serpentine, most likely antigorite.

A tourmaline crystal oddly resembling a rocket because of the 'flames' of muscovite coming off it

If you are a geologist, this is a tourmaline crystal in a metagranite.

If you are a normal person, this is a rocket flying through space 😂

Travelling with samples always stresses me the heck out. Taking some thin sections abroad for a workshop, has anyone ever had a problem with taking them in carry on? Irrationally afraid security will question the glass.
