I've always found ancient continents and super-continents fascinating. Now scientists have found evidence of a now lost micro-continent called Mauritia which existed between 2000 and 86 million years ago. Mauritia was located between India and Madagascar but fragmented when India broke away and headed up towards its eventual collision with Asia.
Grains of sand off beaches in Mauritius were analysed (nice place to do some research) which were found to contain ancient minerals. Zirconium, a mineral commonly found in continental crust, were found in the sand and have been dated between 1,970 to 600 million years old.
