At least twenty geophysical and geological techniques have potential application in orbital and surface exploration programs for locating and evaluating possible waterbearing deposits on the moon. Evaluation of technique applicability requires the formulation of models of the lunar subsurface and specification of lunar rock types and their possible mineralogic, chemical and physical properties. Eight subsurface models and nine rock types are postulated. Lunar rock properties are estimated by evaluation of terrestrial rock measurements and possible modifications produced by lunar genesis and environment. Optimum combinations of surface and orbital methods are selected by comparing calculated or estimated survey responses across the models. Practical difficulties such as weight, power and volume restructions, implanting of electrodes, and drilling are also considered. In practice, data obtained by combinations of methods should be interpreted simultaneously to assure definition of a geologic or structural explanation applicable to all data. The methods recommended for orbital reconnaisance and surveying are photo-television, infrared, radar altimetry and magnetic. Those recommended for surface exploration are gamma ray, television, infrared, gravity, magnetic and electromagnetic. Comprehensive data concerning all equipment types considered are presented.
