The reason there are no shale plays indicated SE of the Appalachian front in SE US is that that terrane is actually a left-behind piece of the African shelf ...

My sister was born in the SE US. I tell her that because that part of the US came from Africa, that she was therefore African-American. In a sense we all are, given the evidence that mankind can trace its ancestry to Africa through DNA analysis.

You wouldn't want to see Gondwanaland amalgamated without a defensive alignment of Laurentia and Laurasia, would you? ;)

Long live Laurentia, death to Gondwanaland!
