  We analyze environmental correlations using mark clustering statistics with
the mock galaxy catalogue constructed by Muldrew et al. (Paper I). We find that
mark correlation functions are able to detect even a small dependence of galaxy
properties on the environment, quantified by the overdensity $1+\delta$, while
such a small dependence would be difficult to detect by traditional methods. We
then show that rank ordering the marks and using the rank as a weight is a
simple way of comparing the correlation signals for different marks. With this
we quantify to what extent fixed-aperture overdensities are sensitive to
large-scale halo environments, nearest-neighbor overdensities are sensitive to
small-scale environments within haloes, and colour is a better tracer of
overdensity than is luminosity.
