Manfile: the University of Manitoba computer-based file of worlds nonferrous metallic deposits
Peter Laznicka · 1975
The need for a systematic compilation of data to support metallogenic research on a worldwide scale was met with development of a computer-based mineral deposit file called MANIFILE (University of MANltoba FILE of world's nonferrous metallic deposits). Data for the file were compiled mainly from published reports scattered through the international, multilingual literature of geoscience. Most data were edited, recalculated or reinterpreted, in order to achieve compatibility. Using the SAFRAS data management system, two sub-files comprising data on about 4 800 deposits, districts and metalliferrous areas of the world were built, which are estimated to account collectively for at least 85 per cent of the world's production and reserves of nonferrous metals. MANIFILE has provided effective support for research at the University of Manitoba in various ways. including the production of selective retrievals, graphic and map plots, and calculations required for analysis of the data.
