I want to know the answer to the following question:
In what type of sea did typical Proterozoic geology come to be?
All the background I'm provided with is that "In contrast to the deep-water deposits of the Archean, the Proterozoic features many strata that were laid down in extensive shallow epicontinental seas; furthermore, many of these rocks are less metamorphosed than Archean-age ones, and plenty are unaltered.". Is that enough to answer the question?
