Comet impact glass! 28,500,000 years old! Above: Front of the Specimen Card. In the southeastern spur of North Africa’s Great Sand Sea, there are several fields of luminous, yellow -green glass known as Libyan Desert Glass (LDG). Due to the lack of any visible impact crater, the most likely source is a low-density asteroid or comet airburst explosion leading to the fusion of silica-rich sands roughly 28,500,000 years ago.
