In addition to a bias in favour of thicker layers, the history of large impacts on Earth provided by spherule layers is probably incomplete, given that only two regions have been systematically ...

These Archean spherule layers are markers of ancient collisions. “In recent years, a number of new spherule layers have been identified in drill cores and outcrops, increasing the total number ...

"Spherule layers, if preserved in the geologic record, provide information about an impact even when the source crater cannot be found," said study lead author Brandon Johnson at Purdue University.

In 2014, while doing fieldwork on Colombia’s Gorgonilla Island, Bermúdez found spherule deposits—layers of sediment filled with small glass beads (as large as 1.1 mm) and shards known as ...
