"In a paper published online Monday in Nature Geoscience, an international research team reports that it has found evidence of a lost
"microcontinent" in the Indian Ocean, northeast of Madagascar. The scientists analyzed sands they found on the beaches of the island nation of
Mauritius and found traces of an ancient mineral called zircon. That's noteworthy because Mauritius is a relatively young, volcanic island, while
zircon is typically found in much older, continental crust."
