...second largest city, where today supermarkets and the luxurious Hotel Leopold II rise from the cool, 5,000-ft.-high plateau. Nor to them does any "outsider" have any right to share in the revenues of the rich mines and plants that produce and process the copper, tin, uranium, and cobalt (60% of free world output) developed by Belgium's fat Union Minière du Haut-Katanga...
...into a sequence of periods: Permian, Jurassic, etc. But seldom do they agree on the age of each period, and a particularly annoying question mark is the Pleistocene, an epoch of intermittent ice ages during which man became true man. The geological dating system that uses the decay of uranium and other radioactive elements to tell the age of very ancient rocks is much too vague for the comparatively short Pleistocene. Dating by carbon 14, which is fine for recent times, reaches back only 60,000 years-not nearly enough...
...system promises to pinpoint the Pleistocene. Developed at the University of Miami by Dr. John Rosholt of the U.S. Geological Survey and Italian-born Dr. Cesare Emiliani, it depends on the fact that a tiny amount of uranium is dissolved in all sea water. When it slowly decays radioactively, it yields protoactinium 231 and thorium 230, both of which attach themselves to sediment particles and sink slowly to the bottom. There they in turn decay, but protoactinium 231 decays faster than thorium 230. The age of sediment on the ocean floor can therefore be determined by measuring the relative abundance...
Gratitude. Born in Brooklyn, Addison was a fast-talking operator and fight promoter before he discovered uranium. Amassing leases that, by his word, cover 300,000 acres in Western states, he began borrowing money from friends in 1956. When he hooked onto the Benson Upgrader, he borrowed some more. His battle cry was: "We just need another $30,000 to get this thing off the ground...
...interest to some of his investors, has even fully paid off a few nervous investors who demanded their money back. But most of the money was devoted to the business-including two executive airplanes and a big house near Denver. So far, the mines have turned out $283.93 in uranium...
