Fluid and deformation induced partial melting and melt escape in low-temperature granulite-facies metasediments, Damara Belt, Namibia.

Ward, Robert Alexander (Stellenbosch : University of Stellenbosch, 2009-03)

Fluid-present partial melting has generally been regarded a poor candidate for effecting crustal differentiation. In this study I report on anatectic metasediments from the Pan-African Damara Belt in Namibia that have ...

Tectonostratigraphic evolution of the Swartland region and aspects of orogenic lode-gold mineralisation in the Pan-African Saldania Belt, Western Cape, South Africa

Belcher, Richard William (Stellenbosch : Stellenbosch University, 2003-12)

ENGLISH ABSTRACT: The Swartland region in the western Cape, South Africa, covers approximately 5000 km2 and forms part of the Pan-African Saldania Belt that represents the southernmost extremity of the Pan-African ...

Chemostratigraphic trends and provenance of the Permian Tanqua and Laingsburg depocentres, southwestern Karoo Basin, South Africa

Van Lente, Belinda (Stellenbosch : University of Stellenbosch, 2004-12)

ENGLISH ABSTRACT: Foreland basins commonly fill with sediment derived from the adjacent fold/thrust belt, providing a relatively simple source-to-basin configuration. However, that is not true for the early southwestern ...

The geology and petrology of the Merelani tanzanite deposit, NE Tanzania

Olivier, Bernard (Stellenbosch : University of Stellenbosch, 2006-12)

Tanzanite, a blue/violet gemstone variety of zoisite (Ca2Al2O.AlOH[Si2O7][SiO4]) is only produced in NE Tanzania. The only known locality is an approximately 7km2 deposit in the Merelani area. It is one of the most sought ...

Petrology and mineral chemistry of sulphide ores and associated metalliferous rocks of the Gamsberg Zn-Pb deposit, South Africa : implications for ore genesis and mineral exploration

Stalder, Marcel (Stellenbosch : University of Stellenbosch, 2004-12)

ENGLISH ABSTRACT: The Gamsberg Zn-Pb deposit is a metamorphosed and multiply deformed sediment-hosted base metal deposit in the central Namaqua Province of South Africa. The deposit is hosted by the Bushmanland Group, a ...
