Applications geophysics to determine the ore body in the work of
investigation of mineral at 1:50,000 mainly in the regions of detailed
investigation of minerals. In this regions, the characteristics of ores and
surrounding rocks was initially determined, therefore, have the facility to
choosing a combinations of methods geophysical optimization search the ore
body. The geophysical methods in each combinations is selected on the basis of
analyzing the origin, characteristics, ore body shape and composition of ore
and elements associated, rocks surrounding to determine the geophysical
anomalies dominant characteristic of the ore body can be observed on the
ground; combined with the results of handling, synthesis geophysical documents
in the schemes geological mapping and mineral survey at 1:50,000 in the country
and study the application of new and modem geophysical methods. This article
introduces selection results the combinatorial of reasonable geophysical
methods to determine the ore body of some metallic minerals originated from
sediments and weathered, non-metallic minerals, radioactive and rare earth in
mineral surveys at 1:50.000, appropriate conditions of geological production
currently in our country
