Spontaneous formation of nonspherical water ice grains in a plasma environment
So 'ice' need not be hidden under the rock/dust layer!
Shall we head down that rabbit hole?

Thermal modelling of water activity on comet doi:10.1093/mnras/stx1607 67P/Churyumov-Gerasimenko with global dust mantle and plural dust-to-ice ratio
Or indeed the 'dust' can be lifted by sublimating gas?
Is near-surface ice the driver of dust activity on 67P/Churyumov-Gerasimenko
