short exploration of the landscape of the Barberton mountains of South Africa - this area holds some of the oldest rocks on earth.
Heart Eyes from a Meteorite The image below is an impact spherule, seen through a microscope in crossed polarized light. An impact spherule forms when a meteorite hits the Earth; on impact, some of the rock on the ground is vaporized, and this vapor expands into a plume of rock particles which cool and condense into molten droplets called spherules. Spherules preserved in the rock layer can offer new information about a meteor impact, even if the crater from the impact has disappeared due to erosion. This particularly happy looking spherule is found in rock from the Barberton Greenstone Belt, one of the oldest and best-preserved examples of Archean continental crust; the spherule records a part of Earth's meteorite impact history as far back as 3.2-3.5 billion years ago. -CEL Sources: http://bit.ly/2ulrrZ4 http://go.nature.com/2foSBvs http://bit.ly/2vBcq9p Image: Seda Özdemir (distributed via imaggeo.egu.eu) http://bit.ly/2ulrrZ4
