Over these past thirteen years, near-IR imaging data from the Visual and Infrared Mapping Spectrometer (VIMS) onboard Cassini gave significant hints on the spectroscopic and geological diversity of the terrains on Titan's surface. The composition of those terrains still remains unconfirmed yet. Nonetheless, by applying a newly updated radiative transfer model, we provide excellent constraints on the composition and structure for the main IR-units present in the equatorial belt (±40°N/S). Indeed, by combining this method of correction with a spectral mixing model for water ice and tholins, we determine the main chemical species present within IR-units and relate them to the observed geomorphology. We therefore propose a scenario that could lead to the current distribution of the IR-units.
