Klerksdorp Sphere

Ottosdal, South Africa

Background

Ottosdal is a small town in South Africa, that is the home of the Klerksdorp Sphere. Ottosdal is a farming community engaged in the growing of grains such as maize, sunflower, and peanuts. In addition, local farmers raise cattle, sheep, pigs, dairy cows and chicken. A major pyrophyllite mine lies near it on the farm Gestoptefontein.

Climate

Ottosdal has a relatively hot and dry climate. Summers are very hot and the very short winter is characterized by cold nights and mild to warm days. The average yearly rainfall is 21.6 inches, and occurs between October and April in the form of heavy thunderstorms. It only snows once a decade at most.

Pyrophyllite Mines

A major industry of the Ottosdal area is the pyrophyllite mines located on the farm Gestoptefontein. These mines produce a very high quality pyrophyllite, which is a phyllosilicate mineral composed of aluminium silicate hydroxide. The pyrophyllite is a metamorphosed clay. The clay was formed by the alteration of volcanic ash, which apparently accumulated at the bottom of a quiet body of water. It forms a dense, but soft light grey, or darker, fine-grained stone, which splits into well-defined slabs. Originally, pyrophyllite was quarried and locally used for tombstones and building stone and to carve ornaments and utensils such as pots, dishes and cases. Currently, it is milled and processed near where it is mined to produce material used for the production of a wide variety of products. They include acid-resistant lab ceramics, refractory bricks and linings, filler in paint, electrical insulation, boilermaker's chalk, chromic-acid purification pots, and crucibles used in the manufacture polycrystalline-diamonds.

The Klerksdorp Sphere

The Klerksdorp Sphere gets its name from a neighboring city museum, called the Klerksdorp Museum.

Shape

The objects can come in many different shapes, but they take on a general round shape. Some vague lines, or grooves, may be seen on the outer surface. These have not been machined by aliens but they display imprints of the fine layering present in the host rock in which they grew.
