  We present an analysis of a highly asymmetric cluster merger from a Chandra
observation of Abell 85. The merger shows significant disruption of the less
massive subcluster from ram pressure effects. Nevertheless, a cold core,
coincident with the cD galaxy, is observed to persist in the subcluster. We
derive dynamical information from the motion of the cold core through the main
cluster's ICM. Multiple derivations of the velocity of the core suggest a Mach
number of M ~ 1.4 or v ~ 2150 km/s, though with substantial uncertainty. We
construct a consistent kinematic model for the merger based on this dynamical
analysis. As has been found for other such "cold fronts," conduction appears to
be suppressed across the front. Thermal conduction may be suppressed by a
magnetic field with a significant component perpendicular to the subcluster's
direction of motion. The effect of the merger interaction in creating and
shaping the observed radio sources is also discussed. It appears most likely
that the radio source is due to distorted and detached lobes from the
subcluster cD galaxy, rather than being a radio halo.
