  Transport in collisionless plasmas is usually called anomalous, being due to
the interaction between the particles and the self-generated turbulence by
their collective interactions. Because of its relevance for astrophysical and
space plasmas, we explore the excitation of turbulence in current sheets prone
to component- or guide-field reconnection, a process not well understood, yet.
We analyze the anomalous transport properties by using 2.5D Particle-in-Cell
(PiC) code simulations. We split off the mean, slow variation (in contrast to
the fast turbulent fluctuations) of the macroscopic observables and determine
the main transport terms of the generalized Ohm's law. We verify our findings
by comparing with the independently determined slowing-down rate of the
macroscopic currents and with the transport terms obtained by the first order
correlations of the turbulent fluctuations. We find that the turbulence is most
intense in the "low density" separatrix region of guide-field reconnection. It
is excited by streaming instabilities, it is mainly electrostatic, "patchy" in
space and so is the associated quasi-periodic anomalous transport. The
remaining irreversible anomalous resistivity can be parametrized by an
effective collision frequency ranging from the local ion-cyclotron to the
lower-hybrid frequency. The contributions to the parallel and the perpendicular
(to the magnetic field) components of the slowly varying, DC-electric fields,
balanced by the turbulence, are similar. This anomalous electric field is,
however, smaller than the contributions of the off-diagonal pressure and
electron inertia terms of the Ohm's law. This result can now be verified by
in-situ measurements of the turbulence, in and around the magnetic reconnection
regions of the Earth's magnetosphere by the multi-spacecraft mission MMS and in
laboratory experiments like MRX and VINETA-II.
