We are constructing a physics-based kinetic model of preferential acceleration and heating of coronal hole heavy ions through their resonant interaction with parallel-propagating ion cyclotron waves. Here, we report on the first steps in this effort. We calculate the resonant heating of O{sup}(+5) ions in a spatially homogeneous system. We find that continual heating is possible, in contrast to the interaction with protons. Large anisotropies are initially produced. This work will form the foundation of our model, which will ultimately include the kinetic response to global forces in a realistic expanding coronal hole.
