Unusual meteorite found in Kansas

Scientists located a rare meteorite in a wheat field thanks to new ground penetrating radar technology that someday might be used on Mars. … experts at the site were able to debunk prevailing wisdom that the spectacular meteorite fall of Brenham, Kansas, occurred 20,000 years ago. Its location in the Pleistocene epoch soil layer puts that date closer to 10,000 years ago. … Fewer than 1 percent of the meteorites discovered on earth are pallasite meteorites, known for their crystals embedded in iron, Mani said.
The team still uncovered a sizeable pallasite buried four feet (1.2-meter) under the ground and located a quarter of a mile (0.4 kilometers) from where Arnold and Mani found the world’s largest pallasite meteorite a year ago.

The newest find weighs 154 pounds (70 kilograms).

The Brenham field was discovered in 1882. Scientists have since traced pieces of the shower as far away as Indian mounds in Ohio, indicating the meteorites were traded as pieces of jewelry and ceremonial artifacts. The site was largely forgotten in recent decades until Arnold and Mani leased eight square miles (20 square kilometers) of it and began looking deep below the surface. – cnn
