What is the oldest mountain range in the world? by Meghan

           The oldest mountain range in the world is the Barberton Greenstone Belt.  The Barberton Greenstone Belt is located in South Africa.  It is also in a part of Swaziland witch is next to South Africa.  Only a small part of the Barberton Greenstone Belt is in Swaziland because most of it is in South Africa.  The Barberton Greenstone Belt is over 3.5billion years old.  Lots of fossils have been found on the mountain that date back to very, very, very, very long ago.  Once a man found gold on one of the mountains and that led to a gold rush.  Of course the gold rush eventually ended.  The mountain is called a greenstone belt because of the green like coloring of some of the minerals in the mountains.  There are more then just the Barberton Greenstone Belt that are greenstone belts.  The Barberton Greenstone Belt is not very big because it has been weathered down but that doesn't stop it from being the oldest mountain range on planet earth.
