- The stone-carved Zimbabwe Bird is the national emblem of Zimbabwe, appearing on the national flags and coats of arms of both Zimbabwe and former Rhodesia, as well as on banknotes and coins (first on the Rhodesian pound and then on the Rhodesian dollar). It probably represents the bateleur eagle (Terathopius ecaudatus) or the African fish eagle (Haliaeetus vocifer). The bird’s design is derived from a number of soapstone sculptures found in the ruins of the medieval city of Great Zimbabwe.
- Basalt (Wikipedia)
Basalt (UK: /ˈbæsɔːlt, -əlt/; US: /bəˈsɔːlt, ˈbeɪsɔːlt/) is an aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the surface of a rocky planet or moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of Venus, which cover ~80% of the surface, are basaltic; the lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars.
