摘要:
In 1857, Adold Erik Nordenskiöld (1832–1901), a Finnish geographer and mineralogist, was forced to withdraw from his position at the University of Helsinki because of a conflict with the czarist officials in Finland. He then moved to Sweden, where he became one of the most celebrated explorers of his time. Most famous of his polar expeditions was the discovery of the Northeast Passage. Nordenskiöld made his voyage in the wooden steamship Vega in 1878–79.Vega started its voyage on June 22, 1878, and was directed in a course around Scandinavia and along the Siberian coast toward Bering Strait. Nordenskiöld's plan was to reach the Pacific Ocean during the summer months, but this was hindered by unfavorable ice conditions. At the end of September the sea was blocked by ice fields, and the Vega had to pass the winter on the northern coast of the Chukchi Peninsula (67°4′49″N, 173°23′2″W)—exasperatingly close to the open waters of Bering Strait. The ship could not set sail any sooner than the following July when the sea was free again. After visiting Japan, China, and Ceylon, theVegapassed through the Suez Canal and finally, on April 24, 1880, ar

摘要:
Because geology professors cannot bring ore deposits from around the globe into their classrooms, the next best thing is to take their students to the deposits, according to David Norman, an associate professor of geochemistry at New Mexico Tech and Angus Moore of the Royal School of Mines. They organized a new exchange program between the New Mexico Institute of Mining and Technology in Socorro, N.M., and the Royal School of Mines in London, England. In May, 14 students from England toured deposits in New Mexico, Arizona, Utah, and Colorado; in the photograph, Norman (on the right) describes a rock from a New Mexico ore deposit to some of the visitors from England. In early June a contingency from New Mexico Tech began studying deposits in England, Spain, and Portugal. Norman and Moore say that the exchange program may be expanded next year.

摘要:
The VGP award was established to honor individuals who in the past 5 years have made a significant contribution to the fields of volcanology, petrology, or geochemistry. The first person chosen to receive this award is Richard A. Yund of Brown University, for his pioneering work on the kinetics of solid state processes in minerals.Dick began his career as a pre‐ then post‐doctoral fellow at the Geophysical Lab, and later at Brown University, where he concentrated on sulfides. After solving some difficult problems of phase relations in sulfide systems and becoming interested in the kinetics and mechanisms of exsolution, he abandoned sulfides and turned his attention to feldsp
