We employed multispectral imaging in the visble and near-IR at four wavelengths (0.73, 0.96, 1.45, and 1.99 &mgr;m) of Copernicus crater in order to map the distribution of olivine-rich, pyroxene-poor material known previously to occur in the central peak complex. We identified three additional portions of the crater to exhibit spectral characteristics similar to those of the central peaks strongly suggesting the presence of material similar to that exposed in the central peaks. These areas are a scarp forming a portion of the northern rim of Copernicus, and two slump blocks in the north wall which may have been derived from the same portion of the ejecta now exposed in the rim scarp. These occurrences decrease the minimum allowable depth for this unusual material in the Copernicus target site though still represent some of the deepest material exposed by Copernicus. ¿American Geophysical Union 1991
