In 2001–2002, a scientific borehole was drilled near the Haciende Yaxcopoil, known as Yaxopoil-1 (or more commonly Yax-1), to a depth of 1,511 meters (4,957 ft) below the surface, as part of the International Continental Scientific Drilling Program. The borehole was cored continuously, passing through 100 meters (330 ft) of impactites.
The impact has been dated to 2,229 ± 5 million years ago, making it the world's oldest confirmed impact structure. [1] This date places the impact in the early Rhyacian, around the end of the Huronian glaciation. The age finding was based on analysis of ancient crystals of the minerals zircon and monazite found in the crater.
