This recent MeFi post links to an intriguing article. In it is described a geological surveying technique. What fantastic technique is this? How does it work?
Armed with the old Russian charts, the United States Geological Survey began a series of aerial surveys of Afghanistan’s mineral resources in 2006, using advanced gravity and magnetic measuring equipment attached to an old Navy Orion P-3 aircraft that flew over about 70 percent of the country. The data from those flights was so promising that in 2007, the geologists returned for an even more sophisticated study, using an old British bomber equipped with instruments that offered a three-dimensional profile of mineral deposits below the earth’s surface. It was the most comprehensive geologic survey of Afghanistan ever conducted.
