Alternating layers of quartzite and shale in the Witwatersrand Ridge in Roodepoort, Gauteng, South Africa
Summary
[edit]
| Description |
Afrikaans: Geologiese lae van die Witwatersrand, Suid-Afrika, sowat 100 meter van die Witpoortjiewaterval en aan die noordelike rand van die Witwatersbekken. Die liggrys lae is kwartsiet wat gevorm is deur sand wat sowat 2 700 miljoen jaar gelede in 'n vlak see afgeset is, en die bruin lae is skalie wat gevorm is deur modder wat in dieper waters van die antieke see neergesak het. Hierdie deel van die 56 km lange rif is binne die Walter Sisulu Nasionale Botaniese Tuin geleë, in Roodepoort, Gauteng.
English: Geological layers of the Witwatersrand Ridge (South Africa) about 100 metres from the Witpoortjie Falls. This site forms part of the northern limit of the Witwatersrand Basin. The light grey layers are quartzite which was formed by sand being deposited in a shallow sea about 2,700 million years ago and the brown layers are shale which was formed by mud that settled in deeper waters of the ancient seas. The part of the 56-kilometre-long (35 mi) ridge is within the Walter Sisulu National Botanical Garden in Roodepoort, Gauteng. |
