Incremental laser space weathering of Allende reveals non-lunar like space weathering effects

•Spectra of weathered Allende have both a lunar and non-lunar space weathering component.•Spectra of Allende became increasingly bluer in the 450–550nm region with laser irradiation.•Characterizing the 450–550 region is important because it is used for spectral classification of asteroids.•Comminution of sulfide phases may be non-lunar phase influencing the UV-VIS continuum.•Spectra of laser weathered Allende are a reasonable match to K- and T-type asteroids.
