Abstract

Abstract

There are two types of assessment methods of area mineral resources: aggregated form assessment and disaggregated form assessment. In aggregated form assessment, it is easy to get assessment of total mineral resources quantity of an area without high level data, but it is void of the message of spatial location of mineral resources, which is necessary to some co-assessments of resources, economy, environment and society. In disaggregated form assessment, work area is firstly divided into same shape grid units and then the mineralization favorableness unit and the mineral resources of unknown units are predicted analogically with known ore bearing units data, but potential resources number of known ore bearing units can not be obtained. So the paper presents a new method assessment of area mineral resources potential combining grid-units-based aggregated form with disaggregated form, in which the disaggregated form assessment number is modified by the information of aggregated form assessment, and at same time the aggregated form assessment result resources are located with the information of disaggregated form assessment. In the paper the method is used to assess Pb-Zn mineral potential of Yunnan Province and gets satisfactary results. The new method is particularly useful to GIS-based co-assessment of resources, economy, environment and society.
