Pilanesberg National Park
The Pilanesberg National Park is located north of Rustenburg in the North West Province of South Africa. The park borders on the Sun City entertainment complex. It is currently administered by the North West Parks and Tourism Board. The area lies in the root zone of an extinct volcano, and is defined by alternating ridges and valleys forming concentric rings, a geological formation that rises abruptly in the form of hills above the surrounding plains. The Pilanesberg is named for chief Pilane of the Kgafêla people, who ruled from Bogopane, Mmamodimokwana and eventually Mmasebudule during the 1800s. The 'Pilanesberg Alkaline Ring Complex' is the park's primary geological feature. This vast circular feature is geologically ancient, being the ring dikes that fed a completely eroded caldera created by volcanic eruptions some 1,200 million years ago. It is one of the largest volcanic complexes of its type in the world, the rare rock types and formations make it a unique geologica ...

Pilanesberg
The Pilanesberg (formerly Pilandsberg) is a mountain in the North West Province, South Africa. The mountain is an ancient volcanic structure, circular in shape, that rises from flat surrounding plains. It is formed by three concentric ridges or rings of hills, of which the outermost has a diameter of about 24 km. The Pilanesberg is located 100 km to the North-West of Pretoria and is for the greater part enclosed in a protected area known as Pilanesberg National Park. The Elands River flows South of the Pilanesberg in an Easterly direction. There are a number of platinum mines right at the perimeter of the crater formation. The name "Pilanes" comes from a historic Tswana chief named Pilane. Geology Although geographically located within the Witwatersrand range, the mountain is geologically part of a feature known as the ''Pilanesberg Alkaline Ring Complex''. It is a vast ring dike of a very ancient extinct volcano that last erupted some 1,200 million years ago. The Pi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Syenite
Syenite is a coarse-grained intrusive igneous rock with a general composition similar to that of granite, but deficient in quartz, which, if present at all, occurs in relatively small concentrations (< 5%). Some syenites contain larger proportions of components and smaller amounts of felsic material than most granites; those are classed as being of . The equivalent of syenite is |
Black Thorn
''Senegalia mellifera'' is a common thorn tree in Africa. The name ''mellifera'' refers to its sweet-smelling blossoms and honey. Its lumber turns pitch black when oiled. Common names of the tree include Blackthorn and Swarthaak (Afrikaans). It is listed as being not threatened. Distribution ''Senegalia mellifera'' is found in the dry areas of Africa and the Arabian Peninsula. Characteristics ''Senegalia mellifera'' can occur either as a multi-trunked bush up to seven metres high with more or less a funnel-shaped crown, or as a single-trunked tree that can reach a height of up to nine metres. It can form an impenetrable thickets. In some areas of Africa, it is considered an invasive species as it can expand into and cover large areas of farmland. Uses In Africa, ''Senegalia mellifera'' is used as fencing, livestock feed and building material for huts. It flowers are sources of nectar for honey-producing bees. The wood is prized also for fuel and making charcoal.Trees o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tamboti
''Spirostachys africana'' is a medium-sized (about tall) deciduous tree with a straight, clear trunk, occurring in the warmer parts of Southern Africa. Its wood is known as tamboti, tambotie, tambootie or tambuti. It prefers growing in single-species copses in deciduous woodland, often along watercourses or on brackish flats and sandy soils. Description The leaves are small, elliptic with crenate margins, and turn bright red in winter before dropping. The petiole has 2 small glands at the distal end. The grey-black rough bark is distinctively split into neat rectangles. The catkin-like flowers appear in early spring before the leaves. Male and female flowers are borne separately on the same tree (monoecious). The small 3-lobed capsules or schizocarps split into three equal indehiscent segments (mericarps or cocci) when ripe; on a warm day this splitting ( dehiscence) can sound like a distant fusillade of shots. The seeds are globose with a chartaceous testa. Wood and toxic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Combretum Imberbe
''Combretum imberbe'' (leadwood, af, hardekool, st, mohwelere-tšhipi, ts, motswiri/mondzo, zu, impondondlovu) is a characteristic and often impressive bushwillow species of the southern Afrotropics. The medium to large tree has a sparse, semi-deciduous canopy of grey-green leaves. The twigs and leaves are hairless as the name ''imberbe'' suggests. Its heartwood is dark brown, close-grained, and very hard and heavy, as suggested by its vernacular name. The durable heartwood is much sought after in the woodcarving industry. The Hereros and Ovambos of Namibia attach special cultural and religious significance to the tree, as to them it is the great ancestor of all animals and people, which must be passed with respect.

Ferricrete
Ferricrete is a hard, erosion-resistant layer of sedimentary rock, usually conglomerate or breccia, that has been cemented into a duricrust by iron oxides. The iron oxide cements are derived from the oxidation of percolating solutions of iron salts.Dictionary of Mining, Mineral, and Related Terms, 2nd Edition. American Geological Institute in cooperation with the Society for Mining, Metallurgy, and Exploration, Inc., 646 p., . Ferricretes form at or near the land surface and may contain non-local sediments that have been transported from outside the immediate area of the deposit. The name is a combination of ''ferruginous'' and ''concrete''. Synonyms include ferruginous duricrust, hardpan and ironpan. Ferricrete deposits along the Animas River watershed in Colorado have been classified as: * alluvial iron oxyhydroxide-cemented conglomerates along old stream channels; * colluvial iron oxyhydroxide-cemented, poorly sorted breccias with massive to minor layering subparallel to hi ...
