6. Chapter 3: Geotourism potential of southern Africa.

Author

Reimold, Wolf Uwe, Whitfield, Gavin, and Wallmach, Thomas

Abstract

Chapter 3 of the book "Geotourism" is presented. It highlights the geological and paleontological progress in South Africa considered as a possible source for the reduction of poverty in its rural region. The United Nations Educational, Scientific and Cultural Organization (UNESCO) has declared the Greater St. Lucia Wetland Park, the Cederberg Wilderness Area and the Cradle of Humankind as World Heritage sites. It also explains the function of the government in nature conservation through the National Heritage Resources Act of 1999.

Abstract

The rare calc-silicate minerals cuspidine, foshagite and hillebrandite occur as late phases in calcsilicate xenoliths from the Rustenburg Layered Suite of the Bushveld Complex. These minerals occur in narrow veins or as replacements, particularly after melilite (cuspidine and hillebrandite) or vesuvianite (foshagite). Cuspidine formed early during cooling, possibly under low-XH[sub 2]O conditions. In contrast, foshagite and hillebrandite formed late in the cooling history, after the infiltration of H[sub 2]O-rich fluids that led to the development of locally pervasive vesuvianite.
