Pink Meteorite reveals rare unstable element

Close-up of a meteorite sample, showing a ceramic-like refractory inclusion (in pink). Refractory inclusions are the oldest-known rocks in the solar system (4.5 billion years old). An analysis of uranium isotope ratios showed that a long-lived curium isotope was present early in the solar system when this inclusion was formed. Look below to see the entire meteorite. Image via Origins Lab, University of Chicago. A pink meteorite inclusion nicknamed Curious Marie shows that a highly unstable element, curium, was present in the early solar system. Researchers have found evidence that curium – a rare unstable heavy element – was present during the early formation of our solar system. Even though curium has long-since decayed into a form of uranium, signs of its presence remain in a pinkish ceramic inclusion nicknamed Curious Marie, a tribute to Marie Curie for whom the element curium was named. This discovery will help scientists refine their models of how elements are forged ...

Diamonds pinpoint start of colliding continents

Jewelers abhor diamond impurities, but they are a bonanza for scientists. Safely encased in the super-hard diamond, impurities are unaltered, ancient minerals that can tell the story of Earth's distant past. Researchers analyzed data from the literature of over 4,000 of these mineral inclusions to find that continents started the cycle of breaking apart, drifting, and colliding about 3 billion years ago. Lead author Steven Shirey at the Carnegie Institution's Department of Terrestrial Magnetism explained: "The Wilson cycle is responsible for the growth of the Earth's continental crust, the continental structures we see today, the opening and closing of ocean basins through time, mountain building, and the distribution of ores and other materials in the crust. But when it all began has remained elusive until now. We used the impurities, or inclusions, contained in diamonds, because they are perfect time capsules from great depth benea...
