Abstract

Summary

Australian geoscientists have made a significant breakthrough in mining exploration by establishing that anomalies of high electrical conductivity in the lower part of the Earth’s crust and upper mantle are commonly observed in the regions with large polymetalic and gold deposits. From these deep zones conductive pathways (fingers) rich with thermal fluids extend all the way to the Earth’s surface (ore deposits). To further develop this idea, Australia is currently conducting broadband MT surveys on a regional scale (1: 5 000 000) of its entire continent (AusLamp project) with the objective to discover new mining provinces. The analysis of MT and MVP data obtained in the territory of other countries which have been actively conducting deep investigations fully support findings of Australian geoscientists. Based on the above, as well as accumulated extensive MT/AMT and MVP surveys experience, it will be expedient to further subdivide exploration in wide depth intervals for new large mineral deposits into 4 stages.
