  4. Whydoes SA have so many different types of minerals in abundance? • ScientiststhinkthattheLate Bombardmenttookplaceabout3 900 millions of yearsago. Manyhugebodies (meteorites etc.) hittheearth. • Meteoritescontainmetalssuch as gold and platinum, and thereforeincreasedtheamounts of thesemetalsonearth. • Diamondswereformedundergreatpressureduringtheformation of thecontinents.
