Abstract

Abstract

Mineral resources quantitative assessment involves processes of constructing models of various types from conceptual model, logical model, and mathematical model to GIS model etc.. Large project like the national project for mineral resource potential assessment currently under operation by the Chinese Ministry of Land and Resources also involves interdisciplinary research teams specialized in geology, mineral deposits, mathematical model and GIS operation etc..It is essential to provide a common platform for these people to exchange ideas and make collective decisions on constructing geological concept models and quantitative models and on GIS procedures for model implementation with actual data input and output. This paper proposes a model builder technology to serve the above purpose. Sophisticated functions such as model iteration and user-machine interaction are developed and implemented in GeoDAS GIS. Case studies of information extraction, spatial analysis, prediction unit delineation and posterior probability mapping involved in gold mineral deposit prediction in Nova Scotia, Canada are covered to illustrate how model builder technology can be used in the whole processes of mineral resource assessment.
