They are volcanic in nature and then eroded to form the very fertile plains.
Also called an Inselberg which is a new word for me tho the meaning is obvious.An inselberg or monadnock (/məˈnædnɒk/) is an isolated rock hill, knob, ridge, or small mountain that rises abruptly from a gently sloping or virtually level surrounding plain. In southern and south-central Africa, a similar formation of granite is known as a koppie, an Afrikaans word ("little head") from the Dutch word kopje.[1] If the inselberg is dome-shaped and formed from granite or gneiss, it can also be called a bornhardt, though not all bornhardts are inselbergs.

Pretty sure the geology is fairly complex but fun to chase down.
Very complex. Lucky some of us engage constructively. Thanks.
My location is a koppie. Very rocky with trees suited to the rocks such as kiepersol or mountain cabbage and resident dashes, or hyrax. Dessie's are my pet hates. They munch my plants and breed like rabbits. Their call is very eerie. Sounds like Chuckie and Freddy on a date.
