The strange race to track down a missing billion years
Zaria Gorvett, BBC News, September 1, 2021

 

A billion years have vanished from the geological record –
and over 152 years after this was first discovered,
scientists can't agree on why.

 

Some papers:


Peters, S.E. and Gaines, R.R., 2012. Formation of the ‘Great

Unconformity’as a trigger for the Cambrian explosion. Nature, 

484(7394), pp.363-366.

S.E., 2019. Neoproterozoic glacial origin of the Great Unconformity.

Proceedings of the National Academy of Sciences, 116(4),

pp.1136-1145. Open access
