Minute balls of clinichlore / chlorite included in some quartz

Minute balls of olive-green clinochlore / chlorite included in some of the quartz crystals we find in the Western Cape, South Africa. This photograph was taken with a microscope camera and the mineral identified by Dr. Cesar Menor-Salván, a scientist and acquaintance of ours, who lives in Spain.

Frequently one finds that there are minute, rusty-coloured indentations on the surface of these crystals. These were probably caused by clinochlore balls that were once on the surface, but have since eroded away, and the dents stained by (?)goethite / iron oxide.
