Electron and ion dynamics are investigated through particle simulation of a supercritical oblique collisionless shock. As theta deviates from 90/sup 0/, ions are accelerated and trapped in the electrostatic wells and later become detrapped; this results in strong ion heating perpendicular to B/sub 0/. Below a critical angle theta/sub t//sub e/ electrons are strongly energized along B/sub 0/, and heated. A large parallel electron current builds up and induces new transverse electromagnetic components in the ramp of the shock. For weaker angles, ion heating vanishes below a second critical angle theta/sub t//sub i/.
