Prospector II

Prospector II has been designed as a frame-based expert system and the successor to PROSPECTOR to assist the geologist in performing regional mineral resource assessments. The changes that have occurred relate to the role of descriptive mineral deposit models in resource assessment and to the arrival of graphics-oriented workstations. These changes have brought about an expansion of the volunteer mode, the glossary of geological terms, and the explanation facilities in PROSPECTOR. The information volunteered by the geologist during a session with Prospector II is used to identify the deposit model that best fits the observations and to provide an explanation of what is explained or not explained by the model, and to indicate what is missing in the observations with respect to the model. The advice that is offered gives the geologist greater confidence in choosing a model and in deciding what additional data are needed to perform an assessment in an area
