Scientists have discovered that a large chunk of the Earth's crust, missing from the geological record and known as "The Great Unconformity," was likely eroded by glaciers during the "Snowball Earth" period. This severe glacial erosion stripped away 3-5 kilometers of rock, which was then washed out to sea, explaining the sharp age changes in rocks observed globally.

Scientists have discovered the location of a large chunk of the Earth's crust that has been missing from the geological record for over a century. The missing rocks were eroded during a period known as "Snowball Earth" when the planet was covered in ice. The erosion resulted in a gap in the sedimentary record, known as "The Great Unconformity." Researchers estimate that 3-5 kilometers of rock were stripped away globally, leaving one billion cubic kilometers of material missing. The missing rocks were likely washed out to sea by glaciers that eroded them.
The Great Unconformity is a geological mystery where up to a billion years of rock and history are missing from the Earth's record. While some theories suggest it was caused by "snowball Earth", a recent study suggests that it was likely caused by the breakup of the supercontinent Rodinia 700-800 million years ago. However, the unconformities seen around the world were not made by a common cause, forming at different times in different locations and for different reasons.
