We show that stochastic acceleration of a Solar composition plasma in the accretion disk of a black hole can lead to enhancements of energetic C and O relative to H and He. The mechanism whereby this occurs is gyroresonance with cascading Alfven wave turbulence, which preferentially accelerates ions with a low charge to mass (Q/A) ratio. For reasonable conditions found near Solar mass black holes, this can produce enhanced energetic C and O abundances, in accordance with COMPTEL observations of nuclear deexcitation line signatures from the direction of the Orion complex. We predict time-variable line signatures due to variations in the accretion rate, along with a radiation pattern consistent with a point source.
