Three vertically insolated samples with different organic-to-ice-to-dust mass ratios at an insolation rate of 1.9 solar constants. The image series show the alterations of the sample surfaces as a function of increasing dust content (online movies). The decreasing sample volume and formation of fractures (some marked with arrows) is most evident at a component mass ratio of 5:100:300 and reduces significantly with increasing dust content. The surface-altering activity of the first sample comes to an end after 12 h. The following series show the dust-dependent reduction of the surface alterations and the timescales on which they occur. At a maximum relative dust amount of 5:100:700 per mass, the duration of visible sample alteration is reduced to 8 h.
