Mobile MT – Providing Visibility in the Third Dimension
Aurania’s MobileMT surveys in Ecuador aim to detect rocks that conduct electricity due to their high sulphide content as this could show where a mineral deposit is located. Conversely, rocks that are poor conductors, possibly due to silica flooding, are commonly associated with epithermal deposits.
MobileMT relies on the fact that lightning creates electromagnetic energy fields that propagate around the world as plane waves, bouncing between the ground and Earth’s ionosphere.
The energy fields induce electrical currents into the rocks below surface, and the extent to which this current is conducted can be measured by sensitive copper coils flown above the forest canopy.
After processing the data, our technical teams are able to build a very detailed three dimensional conductivity map of the earth down to a depth of approximately 1 to 2 kilometers below surface, depending on the given objective in a particular area.
The MobileMT system measures not only electrical data, but also magnetic data.
