Metamorphic infrastructure in the northern Ruby Mountains, Nevada Metamorphic infrastructure in the northern Ruby Mountains, Nevada
The metamorphic complex of the northern Ruby Mountains in northeastern Nevada exposes Paleozoic strata that are metamorphosed to sillimanite grade, migmatized, and recumbently folded. Nappes are variously overturned to the east, north, south, and west. The deeper part of this metamorphic infrastructure is a migmatitic zone pervaded by pegmatitic two-mica granite. A structurally higher...

Revised geomagnetic polarity time scale for the interval 0–5 m.y. B.P. Revised geomagnetic polarity time scale for the interval 0–5 m.y. B.P.
A change in the constants used in K‐Ar dating and a significant increase in new data have made a recompilation and recomputation of data used to define the Late Cenozoic K‐Ar polarity time scale highly desirable at this time. All available data in the range 0–5 m.y. have been recalculated using the refined constants, with 354 data points in this time interval now meeting the minimum...

Geomagnetic paleointensities by the Thelliers' method from submarine pillow basalts: Effects of seafloor weathering Geomagnetic paleointensities by the Thelliers' method from submarine pillow basalts: Effects of seafloor weathering
Measurements of geomagnetic paleointensity using the Thelliers' double‐heating method in vacuum have been made on 10 specimens of submarine pillow basalt obtained from 7 fragments dredged from localities 700,000 years old or younger. In the magnetic minerals, the titanium/iron ratio parameter x and the cation deficiency (oxidation) parameter x were determined by X‐ray diffraction and...

Assessing Metallic Resources in Alaska Assessing Metallic Resources in Alaska
In the last two decades federal and state governments have become in creasingly preoccupied with classi fying public lands according to the uses that may be made of them. One outcome of the classifying can be a change in the land's legal status from one in which any use is tolerated to one in which only selected activities are allowed. Since such a change af fects the economic and...
