    Notes: Summary The Finnish Ore Data File has already provided valuable experience on building, maintaining, and using an extensive data file with a great diversity of data. The file attempts to accommodate all relevant data on ore deposits in metamorphosed and strongly deformed Precambrian terrain. Because the deposits dealt with are generally well-studied and documented, they provide a great deal of precise information on ore deposits. The question arises as to how the system could be used internationally, especially bearing in mind developing countries. The two problems which should be solved for this purpose are: first, the forms, codes, and programs should be translated from Finnish into English; second, the structure of the file should be simplified to meet the demands of less studied areas and deposits. However, both problems could be resolved relatively easily without changing the basic principles involved.

    Notes: Abstract Data from 34 Ni−Cu deposits of the 315c-striking, 420-km long, and 10–40-km wide Kotalahtinickel belt have been recorded in the previously described system of the Ore Data File of Finland. For comparison data from four Ni−Cu deposits outside the belt have been collected. The statistical treatment of the data begins with cluster analysis and four classes are distinguished on the basis of 303 data elements. These classes form eight groups within the linear belt. Two groups containing the largest deposits, Hitura and Kotalahti, are processed by characteristic analysis, and factor analysis is applied to test the interdependence of the characteristics.
