Abstract. Using time dependent MHD simulations, we study the nature of three-dimensional mag-
netic reconnection in thin quasi-separatrix layers (QSLs), in the absence of null points. This process is
believed to take place in the solar atmosphere, in many solar flares and possibly in coronal heating. We
consider magnetic field configurations which have previously been weakly stressed by asymmetric
line-tied twisting motions and whose potential fields already possessed thin QSLs. When the line-tied
driving is suppressed, magnetic reconnection is solely due to the self-pinching and dissipation of nar-
row current layers previously formed along the QSLs. A generic property of this reconnection process
is the continuous slippage of magnetic field lines along each other, while they pass through the current
