Aerial view of a section of the Northern Cape, South Africa, with Biega se Berg, at the center of the picture. The latter is a mountain at the center of a prominently oval-shaped dolerite saucer.
Summary
[edit]
| Description |
Afrikaans: Uitsig noordwaarts oor die Bo-Karoo, Noord-Kaap, Suid-Afrika, tydens 'n vlug tussen Dubai en Kaapstad. In die middel, direk links van die Ongers-Brak-samevloeiing, is 'n dolerietpiering met Biega se Berg (1 102 m) in die midde daarvan. Moontlik was die intrusiegang meer aaneenlopend en effens gevou, sodat areas wat in hoër areas gevou was, later geërodeer is om slegs die trog-doleriet met gevolglike ovaal vorm agter te laat.
Die Ongersrivier (van onder) vloei met die Brakrivier (van regs) naby hierdie berg saam, en die Brak- het 'n samevloeiing met die Oranjerivier op die agtergrond. Die beddings van die Ongers- en Brakriviere is dig met akasiabome begroei wat uit ongereelde vloede en ondergrondse beddingwater voordeel trek, om 'n illusie van staande water te gee. English: Looking north over the Karoo, Northern Cape, South Africa, during a flight between Dubai and Cape Town. At centre, to the immediate left of the Ongers-Brak confluence, is a dolerite saucer, with Biega se Berg (1,102 m) situated at it centre. It is possible that the sill was more continuous and gently folded, so that areas folded into higher areas have been eroded, leaving only the dolerite in the trough behind, with the resultant oval shape. The Ongers River (from below) joins the Brak River (from the right) near this mountain, and the Brak has a confluence with the Orange River in the background of the picture. The river beds of the Ongers and Brak rivers are densely vegetated with Acacia trees which benefit from occasional floods and subterranean water, giving the illusion of standing water. |
