Key Facts and Figures. The first diamond, the appropriately named Eureka, was discovered in South Africa near Hopetown in 1867 — it weighed 21.25 carats. The largest diamond discovered was the Cullinan found at the Premier Mine in 1905 — it weighted 3,106 carats uncut. At the start diamond discoveries were in alluvial deposits — in 1869 ...

Tsavo East National Park is the larger of the twin parks, covering 13,700km² (1,370,000 hectares), and is also the more arid of the two. Apart from some crags around Voi and gorges around the Galana River, Tsavo East consists mostly of plains of grassland and savanna that stretch as far as the eye can see. The park receives fewer visitors than ...

Just as the Turkwel River, the shallow alluvial aquifer (SAA) was dominated by Ca–HCO3 water type, while the TGSA was Na–Cl water type and became Na–HCO3 near the Holocene sediments.

Introduction. Kenya has a very wide range of soils resulted from the variation in geology (parent material), in relief and climate. Soil resources vary from sandy to clayey, shallow to very deep and low to high fertility. However, most of them have serious limitations such as salinity/ sodicity, acidity, fertility and drainage problems.
