Abstract

Naturally disaggregated specularite-bearing sandstone from the Triassic Moenkopi Formation, artificially deposited in controlled magnetic fields of ???5 ?? 10-2 mT, acquires a stable remanent magnetization that has systematic errors in inclination and declination. Inclinations about 12?? shallower than the applied fields are produced by deposition on a horizontal surface in still water. Deposition from flowing water on a surface inclined 6-10?? results in inclination errors of as much as 20??. Water flowing obliquely to the applied field results in declination errors of about 10??, with declinations systematically rotated toward the upstream direction of current flow. These experimental results indicate that specularite-bearing sediment responds to the earth's field in a manner similar to magnetite-bearing sediment, and support observational evidence for a primary magnetization of depositional origin in specularite in red beds of the Moenkopi Formation. ?? 1980.
