Croizat made novel predictions about the existence of tectonic structures
in the present that had not already been 'observed' so he was not making
predictions of what might be experienced in the future unless one could say
that he was predicting a future empirical discovery also.

Agreed. However it shows that testing of itself is problematic as a
demarkation criterion between 'science' and 'non-science'.
