Low-flying airplane mapping mineral resources in US

US: US Geological Survey is gearing up to map buried geological features that provide clues into mineral resources in Essex and Clinton counties in New York. The surveys will measure subtle changes in Earth’s magnetic field that reflect different types of buried rock. They will also measure low, background levels of natural radioactivity that help with mapping different types of surface rocks. Together, these data will allow visualization of geological structures at and beneath the surface. The flights, which will take place at altitudes as low as 400 feet above ground level, are expected to take about seven days to complete but may be spread over a few weeks due to weather considerations. Should snow blanket the area and stay the flights may be postponed until spring, as snow on the ground affects how well the sensors work.
