 We introduce analytical quantum gravity modifications of the production cross
section for terascale black holes by employing an effective ultraviolet cut off
$l$. We find the new cross sections approach the usual "black disk" form at
high energy, while they differ significantly near the fundamental scale from
the standard increase with respect to $s$. We show here that the 
discontinuous step function used to represent the cross section threshold can
realistically be modeled by two functions representing the incoming and final
parton states in a high energy collision. The growth of the cross section with
collision energy is thus a unique signature of $l$ and number of spatial
dimensions $d$. If these predictions prove to be model-independent, they
suggest black hole formation might be virtually impossible for collision
energies less than 100 TeV. While no such signals would be observed at the LHC,
attention should be focused on ultra-high energy cosmic ray events.
