The dome is a vast basin formed when a meteorite hit the earth some two billion years ago. |
Vredefort Dome, approximately 120km south west of Johannesburg, is a representative part of a larger meteorite impact structure, or astrobleme. |
A well-known older astrobleme situated in the margin of the Mesoprotozoic Superior craton provides a good example of meteorite fall. |
Discovered at Reckling Peak, Antarctica, this type of meteorite is known as an achondrite. |
Sornette's discussion of the science of earthquakes, volcanic eruptions, hurricanes, tornadoes and meteorite impacts is riveting. |
Nearby is a unique 60-cm-high Boguslavka iron meteorite, which is the fragment of a single, giant monocrystal of kamacite. |
