The colour patterns observed on Io indicate extensive surface flows of quenched molten sulphur 
Volcanic resurfacing rates and implications for volatiles on Io
Resurfacing rates and surface ages on Io are estimated, together with the material ejection and deposition rates of the active volcanic plumes.
The role of SO2 in volcanism on Io
Io and Earth are the only planetary bodies known to be volcanically active; the energetics of the eruptive plumes on Io have important structural implications and are closely linked with the presence
Erosional scarps on Io
Irregular or fretted scarps on Io are similar to those found on Earth and Mars. A sapping mechanism involving liquid SO2 is proposed to explain these complexly eroded terrains on Io.
Volcanic features of Io
Volcanic activity is apparently higher on Io than on any other body in the Solar System. Its volcanic landforms can be compared with features on Earth to indicate the type of volcanism present on Io.
Colored lava flows on the earth : A warning to Io volcanologists
Pale coatings of amorphous silica, sulfur, and sulfur-bearing compounds can form on terrestrial basalt flows while they are still active and subsequently on timescales ranging from days to years
Preliminary geological mapping of Io
Terrain units and their global distribution on Io are summarised. A map of the complex region of Io is also presented.
Pyroclastic sulphur eruption at Poás volcano, Costa Rica
The recent Voyager missions to Jupiter have highlighted the role of sulphur in volcanic processes on Io1–7. Although fumarolic sulphur and SO2 gas are almost universal in terrestrial active

Spectral evidence for sublimates and adsorbates on Io
The reflectance spectrum of Io can be explained by a surface layer consisting of fine-grained particles of sublimated alkali sulphides and sulphur on which H2S and SO2 are adsorbed.

Volcanic eruption plumes on Io
An umbrella-shaped plume detected above Io confirms that Io is volcanically active. Preliminary analyses of eight such eruptive plumes are presented.

Melting of Io by Tidal Dissipation
The dissipation of tidal energy in Jupiter's satellite Io is likely to have melted a major fraction of the mass. Consequences of a largely molten interior may be evident in pictures of Io's surface
Identification of gaseous SO2 and new upper limits for other gases on Io
Gaseous SO2 has been identified on Io. The estimated abundance of 0.2 cm atm is consistent with an atmosphere in equilibrium with solid SO2 at the local surface equilibrium temperature. Preliminary
Anomalous light scattering in liquid sulfur at the polymerization transition.
TLDR
It is shown how the anomalous light scattering can apparently increase the measured value of the absorption coefficient of the liquid and how it can be used to measure the polymerization temperature of liquid sulfur or similar systems.
