The silica/alumina-based surface coatings of rocks from the Ka'u Desert and Mauna Kea regions of Hawaii are characterized using electron-microprobe analysis and microscopy, and the mechanisms of their deposition are investigated in laboratory simulations. The results are presented in tables and graphs, and it is found that the coatings are derived from local exogeneous materials. The coating process involves wind deposition of fine-grained clastic material, nonviolent wetting by fog or dew leading to partial solution of the clastic deposits, evaporation and precipitation of ordered mineral phases with incorporation of some clastic particles, and removal of some late-stage precipitates by rainfall. The importance of these coatings for the interpretation of remote-sensing data such as Landsat or 8-14-micron thermal-IR images is indicated.
