  In the framework of non-riemannian geometry, we derive exact static vacuum
solutions of the field equations obtained from the full equivalent version of
the Einstein-Hilbert action when torsion degrees of freedom are taken into
account. By imposing spherical symmetry and a suitable choice for the
contorsion degrees of freedom, the static geometry provides deviations on the
predictions of the observational tests predicted by General Relativity --
namely on the advance of planetary perihelia and the bending of light rays --
which we infer. The analytical extension is built in two particular domains of
the parameter space. In the first domain we obtain a solution exhibiting an
event horizon analogous to that of the Schwarzschild geometry. For the second
domain, we show that the metric furnishes an exterior event horizon, and two
interior horizons which enclose the singularity. For both branches we examine
the effects of torsion corrections on the Hawking radiation. In this scenario
the model extends Bekenstein's black hole geometrical thermodynamics, with an
extra work term connected to a torsion parameter.
