SELENOLOGY Water on the Moon? For a decade, McDonnell Douglas Geologist Jack Green has stoutly argued that there is water on the moon. Not free-flowing, gurgling water, to be sure, but water that is chemically locked within rock. Now, with the aid of a half-century-old observation, he reported to an American Institute of Aeronautics and Astronautics meeting in Los Angeles last week, he has found additional evidence of lunar water...
Repeating Wood's experiment with a filtered, 8-in. telescope, Green produced lunar pictures with black spots near the crater Aristarchus, from which astronomers have reported seeing a red glow-a possible sign of volcanic activity. To Geologist Green, it all makes sense. Sulphur is the most abundant of volcanic materials, he says, and wherever volcanic sulphur is found on earth, it is surrounded by hydrous rock...
...destined to change. Nestled next to Communist-ruled Tibet, Bhutan has become a last frontier between China and India-and one of the most strategic chunks of geography on earth. To dispel some of the question marks, its progressive king, Jigme Dorji Wangchuk, 39, recently invited three Swiss scholars, Geologist Augusto Gansser, his photographer daughter and Vienna-born Tibetologist Blanche-Christine Olschak, to observe and record the whole spectrum of Bhutan's culture. They have emerged with a fascinating photographic record including temples and monastic art treasures seen hitherto only by privileged lamas (see color opposite...
...this fascinated U. S. Marine Geologist James W. Mavor Jr. of the Woods Hole Oceanographic Institution, who sailed to Thera last year in the institute's research vessel, Chain. When his seismic profiles of the island showed geophysical conformations that seemed to match Plato's description of Atlantis, Mavor organized a full-fledged expedition headed by Greek Archaeologist Spyridon Marinates and including Professor Emily Vermeule, research fellow at Boston's Museum of Fine Arts. Shortly after the diggers arrived, they detected artifacts buried in a 2,500-ft. swath across the island. Digging nine trenches, the group...
...distribution and radioactive dating of these tek- tites, scientists had long assumed that the meteorite weighed a few thousand tons and struck about 700,000 years ago. While he was examining sediment cores taken from more widely separated locations on the floors of the Indian and Pacific oceans, Geologist Glass discovered tiny tektites, apparently from the same meteorite. To have littered so large an area, Glass and Heezen calculated, the meteorite could have weighed a billion tons and might have been as large as a mile in diameter. Even more intriguing, further examination of the sediment cores indicated that...
