  We examine the properties of TeV-scale extra dimensional black holes (BH) in
Randall-Sundrum-like models with Gauss-Bonnet higher-curvature terms present in
the action. These theories naturally lead to a mass threshold for BH production
in TeV particle collisions which could be observable at LHC/ILC. The lifetimes
of such BH are examined and, in particular, we focus on the predicted lifetime
differences between the canonical and microcanonical thermodynamical
descriptions of BH decaying to Standard Model brane fields and the possibility
of long-lived relics. The sensitivity of these results to the particular mix of
fermions and bosons present in the Standard Model spectrum is also briefly
examined.
