SUMMARY

Selection of combinations of reasonable geophysical methods for determining the primary ore body of some kinds of minerals with endogenous and metamorphic origins in mineral survey at 1:50.000 scale

Phùng Thế Lễ

The use of a combination of geophysical methods to search and identify primary ore bodies in geological mapping and mineral survey at 1:50.000 scale has been carried out mainly in the areas of detailed investigation of minerals. In these areas, geological data show mineral prospect and initially identified the characteristics of ores and surrounding rocks; so there is a basis for choosing the optimal combination of geophysical methods for effective prospection of ore bodies.

From the results of synthetic processing of geophysical and geological materials from all projects of geological mapping and mineral survey at 1:50.000 scale realized from 2000 to present, combined with results of study on the application of modern geophysical methods, this article presents some combinations of geophysical methods used for reasonably identifying primary ore bodies of endogenous origin and origins related to magma and metamorphism in geological mapping and mineral survey at 1:50.000 scale.
