Analyzing Ancient Sediments at Warp Speed
Like a toy out of a science fiction story, the X-ray fluorescence core scanner reveals intimate details of the composition of ancient mud and sediment–which can contain a variety of clues about past climate and environmental conditions on Earth–without breaking the surface. In a matter of hours, the XRF simultaneously captures digital photographs and X-ray images of every millimeter of a core sample, while detecting the presence of any of 80 chemical elements.
