Lake St. Gene shows microscopic evidence of impact event with bedrock prology

Lake St. Gene shows microscopic evidence of impact event with bedrock prology. Lake St. Gene basin suspected as impact site Catastrophic drainage occurred past Saguenay Microscopic evidence found in Pennsylvania and New Jersey

Researchers point to the Corossol structure in the Gulf of St. Lawrence as a potential impact site. Microscopic evidence found in Pennsylvania and New Jersey matches bedrock composition only from this Quebec region. Catastrophic drainage appears to have routed material southward through the Saguenay area. The provenance match is described as compelling evidence.

Key Facts

• Lake St. Gene basin suspected as impact site
