Prof Marian Tredoux is a geochemist and lecturer in the Department of Geology at the University of the Free State (UFS). Her research interests are rocks, particularly the chemistry of rocks and the minerals they are composed of – chemicals similar to those found in laboratories, although they occur in nature.
Prof Tredoux started her research career at the University of the Witwatersrand (Wits), after which she spent a number of years at the University of Cape Town (UCT). For the past 11 years, she has been at the UFS, which has brought her in close proximity of her primary field-research area in Barberton. This fascinating part of the country has been the focus of her research for 30 years. She has always been intrigued by the earth's crust in this area, which she describes as "very old, very strange, and very interesting".
Prof Tredoux has been collaborating with colleagues and peers overseas in an attempt to unravel the intricacies of this unusual geological area. Some of these colleagues recently discovered a new mineral in one of the rock formations of the Barberton mountain range. They decided to name the mineral after Prof Tredoux, dubbing it tredouxite. "I am very honoured by this, and very grateful that all these years of collaboration are being acknowledged," Prof Tredoux said.

The interior perforated aluminium planetarium dome has been installed by an American expert from Astro-Tec, the American company that customised the dome for the planetarium on Naval Hill. The planetarium, the first digital planetarium in sub-Saharan Africa, is scheduled to open in November 2013. The UFS manages the project.
The dome arrived in parts by ship from the USA in June 2013. These parts consisted of a number of long curved ‘ribs’ and numerous perforated panels. The panels were attached in sections to the ribs to form a smooth concave shell, creating the surface for the projection system.
The next step will be the installation of the projection system itself.
The 86-year old Lamont-Hussey Observatory on Naval Hill, also known as the Sterrewag Theatre, is home to the planetarium. The planetarium is the first component of a proposed Centre for Earth and Space. This will be a multi-purpose facility to promote science communication and preservation, and the arts.
This project is a long-term partnership between three main organisations, each bringing essential components to the project: the Mangaung Metro Municipality (MMM) as the land-owner, the Free State Department of Economic Development, Tourism and Environmental Affairs (DETEA) and the UFS, which developed the concept for the planetarium project and will be responsible for its operation and further fundraising endeavours.
The National Department of Science and Technology also joined this venture subsequent to providing substantial funding to the UFS in order to purchase the projection system for the planetarium.
