From National Geographic News:
India’s Vindhyan Basins have hidden their age well-by as much as 500 million years, according to controversial new research.
The basins, which stretch across a 39,000-square-mile (100,000-square-kilometer) swath of central India, were initially believed to have formed about 500 to 700 million years ago after Earth’s crust stretched, thinned, and then faulted.
Six of the basins studied, however, show evidence that they were created a billion years ago, said study lead author Joseph Meert, a geology professor at the University of Florida.
