Its a question that occupies lots of ongoing research even today. To start, Id see whether you could get an easyshare copy of Rodgers and Santosh' book Continents and Supercontinents
, its one of the bset books on thi very subject. Remember before a specific time it would be virtually impossible to determine the answer to your question because the earth was moltedn. We use certain minerals and patterns on such things as Shield Rocks to "Speculate" about their position above a sea level datum (if indeed, such a datum even existed at the time we measured the zircon ages).
We mostly use the existence of free quartz, clastics, and metamorphosed sandstones to determine the existence of an emergent craton or cratonic shelf.
