{"Image DocumentName": "Terrestrial Xenology", "Image ImageDescription": "It is hard to tell how much of the fissiogenic Xe in the MORB data comes from early 244Pu decay and how much from continuing 238U decay over the whole age of the Earth. However, very high precision data in 1998 showed that ~30% of the fissiogenic Xe in MORB is from 244Pu decay based on slightly different production ratios of 131Xe, 132Xe, 134Xe, and 136Xe. Note air has only 244Pu-generated fission Xe.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
