摘要:

About 20% of the United States, including the regions of the Great Lakes and the Great Salt Lake, has entered a fourth year of record and near‐record streamflow and lake levels, according to the U.S. Geological Survey (USGS). From June 3 until June 8, 1986, the Great Salt Lake stood at 1283.77 m above sea level, 0.076 m above the previous record, which was set in 1873. (Records have been kept for the lake since 1847.) On June 8, a dike south of the lake gave way during a windstorm, causing flooding of evaporation ponds used for mineral recovery.As a result of the breach, the lake's level dropped to 1283.65 m above sea level by June 10 but rose to 1283.68 m by June 20. The latest official reading, made on June 30, showed that the lake's level had dropped to 1283.63 m above sea level. According to Tom Ross, chief of the Current Water Conditions Group at the USGS National Center in Reston, Va., this drop represents “a normal seasonal decline brought on by evaporati

摘要:

Metamorphic Reactions: Kinetics, Textures, and Deformationis the fourth in a series of books published under the series titleAdvances in Physical Geochemistry. The book is divided into three parts. The first contains five papers dealing with reaction kinetics and their effects on metamorphic assemblages. The opening paper, by M.A. Carpenter and A.P. Putnis, discusses the effects that cation order/disorder and metastable crystallization might have on the interpretation of mineral assemblages. This is followed by a discussion of the kinetics of metamorphic reactions (D.C. Rubie and A.B. Thompson) that summarizes a wide range of experimental and theoretical studies on mineral nucleation and growth rates.

摘要:

Abel Wolman was born in Baltimore in 1892. He attended public schools and entered the Johns Hopkins University. A premed major, he graduated in 1913. As one of his brothers was already a doctor, the family decided that the opening of a new engineering school at Johns Hopkins provided a new opportunity.

摘要:

The editors of Geophysical Research Letters (GRL) invite the submission of manuscripts for a special issue on the geophysics of the core and the core‐mantle boundary in commemoration of the 50‐year anniversary of the discovery of the inner core by Inge Lehmann. Manuscripts should be submitted to GRL coeditor Rob Van der Voo (Department of Geological Sciences, University of Michigan, Ann Arbor, MI 48109) before August 30, 1986, in accordance with the usual rules for manuscript submission. Submissions will undergo the usual rapid GRL review procedure. Camera‐ready copy will be due by November 3, 1986; the special issue will be published in December
