Summary:

Throughout the world, many palagonites have formed under different weathering conditions out of which only some are known to exhibit Mars-like spectral properties. However, in Hawaii certain palagonites are considered to be among the best analogs for Martian fines, based upon similar spectral properties. Even though the identification of minerals in palagonitic materials is important for the interpretation of the genetic processes, and work has been done on the mineralogy of palagonites, detailed mineralogical information for Martian spectral analog palagonites is rather scarce. As a result, the objective of this study is to characterize the mineralogy and spectral properties of three slightly palagonitized basaltic tephra samples. These samples were collected near the summit of Mauna Kea, on the island of Hawaii, in an effort to contribute to the basis for inferring mineralogy and processes for Martian surface materials.
