Book review: Geomagnetism of baked clays and recent sediments Book review: Geomagnetism of baked clays and recent sediments

This book is an outgrowth of the symposium entitled “Time Scales of Geomagnetic Secular Variations,” which was held at the 4th Assembly of the International Association of Geomagnetism and Aeronomy (Edinburgh, U.K., August 1981). The volume includes many of the papers presented, which described paleomagnetic results from both archeologic materials and Holocene geologic deposits, as well...

Transitional paleointensities from Kauai, Hawaii, and geomagnetic reversal models Transitional paleointensities from Kauai, Hawaii, and geomagnetic reversal models

Previously presented paleointensity results from an R-N transition zone in Kauai, Hawaii, show that field intensity dropped from 0. 431 Oe to 0. 101 Oe while the field remained within 30 degree of the reversed axial dipole direction. A recovery in intensity and the main directional change followed this presumably short period of low field strength. As the reversal neared completion, the...

Geomagnetic paleointensities from excursion sequences in lavas on Oahu, Hawaii Geomagnetic paleointensities from excursion sequences in lavas on Oahu, Hawaii

Paleomagnetic data demonstrating three late Tertiary excursions in the direction of the geomagnetic field recorded in sequences of basaltic lavas on the island of Oahu, Hawaii were published by R. R. Doell and G. B. Dalrymple in 1973. We have determined geomagnetic paleointensities by the Thelliers' method for 14 lavas from the three sites. During these experiments, considerable...

Slope-stability analysis and creep susceptibility of Quaternary sediments on the northeastern United States continental slope Slope-stability analysis and creep susceptibility of Quaternary sediments on the northeastern United States continental slope

The continental slope off the northeastern United States is a relatively steep, morphologically complex surface which shows abundant evidence of submarine slides and related processes. Because this area may be developed by the petroleum industry, questions arise concerning the potential for further slope failures or unacceptable deformations and the conditions necessary to cause such...

Alternative diagenetic models for cretaceous talus deposits, Deep Sea Drilling Project Site 536, Gulf of Mexico Alternative diagenetic models for cretaceous talus deposits, Deep Sea Drilling Project Site 536, Gulf of Mexico

Talus deposits recovered from Site 536 show evidence of aragonite dissolution, secondary porosity development, and calcite cementation. Although freshwater diagenesis could account for the petrographic features of the altered talus deposits, it does not uniquely account for isotopic or trace-element characteristics. Also, the hydrologic setting required for freshwater alteration is not...
