The imaging technique known as x-ray microtomography allows geologists and meteorite researchers to probe the internal structure of solid materials in three dimensions at extremely detailed resolution, up to 1 micron (1/1000th of a millimeter) per voxel (cubic pixel). Dr. Friedrich will discuss how this technique works and how it is used to investigate physical structure of meteorites and to reconstruct their impact history. This can provide information on the meteorite’s parent body. In the case of ordinary chondrites, these parent bodies are the earliest relics of the newly formed solar system.
Jon Friedrich is a Professor of Chemistry at Fordham University. He studies the chemical and physical processes shaping the early solar system. He earned a Ph.D. from Purdue University and is a Research Associate of the American Museum of Natural History.
Pre-lecture socializing with fellow WAA members and guests begins at 7:00 pm!
