yeah it was never explained. And I guess never even thought to use it againt naruto's sage mode. though it's interesting to know that there is a jutsu to counter sage mode. and the only person alive who knows about it is sasuke. and the only people who can do sage mode is narutu and kabuto. Maybe it could have been a jutsu that overloads or ruins the control of Nature energy in the person and thus turn the person himself into stone? well it seems to be well one hit move since hashirama thought it would be enough for sasuke to stop him.
