Stilbite and Associated Minerals from the Butha-Buthe District, Lesotho, Southern Africa

All specimens featured here were collected by Herman du Plessis

The mountain kingdom of Lesotho is located in southern Africa, landlocked and surrounded on all sides by the Republic of South Africa. The entire country lies at an altitude of at least 1,000 meters above sea level, and most of the terrain is above 1,800 meters. The highest peak is Thabana Ntlenyana, which rises 3,482 meters above sea level. Because of its mountainous setting, snow falls during the winter months, and the average annual temperature can vary from 30°C (86°F) in the summer to –18°C (0°F) in the winter.

 

Dr. Bruce Cairncross, a consulting editor of Rocks & Minerals, is a professor of geology at the University of Johannesburg.

Herman du Plessis is an avid field collector. Most of his mineral specimens have been personally collected in regions such as Namibia, South Africa, and Lesotho.
