Rapid Variation of the Geomagnetic Field in Reversal: Evidence from the Sheep Creek Range, North-Central Nevada
(2004-01-01)A paleomagnetic study of middle-Miocene basalts from the Sheep Creek Range of north-central Nevada was conducted to investigate prior evidence of extremely rapid change in geomagnetic field direction during a polarity ... -
Complex magnetization of a 15.6 my old transitionally-magnetized lava flow: geomagnetic field change during cooling or lightning-induced remagnetization?
(2008-01-01)A paleomagnetic and rock magnetic study of a lava flow (VC 9 in the Sheep Creek range of North Central Nevada) suspected of recording extremely rapid field change demonstrates that its inhomogeneous remanence is more likely ... -
Lateral Variation in Rock Magnetic Properties and Natural Remanence in a 15 my old Lava Flow, Sheep Creek Range, North Central Nevada
(2006-01-01)A paleomagnetic and rock magnetic survey of two vertical profiles through a basaltic lava flow in the Sheep Creek Range of Northern Nevada showed that magnetic properties of the lava vary laterally. Previous studies of ... -
Improved Simulation of Lava Flow Cooling Supports Hypothesis of Rapid Transitional Geomagnetic Field Change
(2011-01-01)Results from an improved one-dimensional conductive cooling model confirm the findings of Bogue and Glen (2010) that a partially thermally remagnetized lava flow in the Sheep Creek Transition Zone records a rapid transitional ... -
Miocene Basalts from Joshua Tree Show Fault Block Rotation
(2010-01-01)Paleomagnetic study of Miocene basalts collected from a locality 7km north of Desert Center, CA (33.7N, 244.6E) shows that rocks are rotated 46.6? in a clockwise direction, results inconsistent with previous kinematic ... -
Rapid Field Change in a Single Lava Flow
(2005-01-01)A paleomagnetic survey conducted on a basaltic lava flow in the Sheep Creek Range of Northern Nevada revealed what appears to be a 50? change in the direction of the magnetic field that occurred during the cooling of the ... -
Rapid Variation of Field Strength during a Geomagnetic Polarity Reversal
(2003-01-01)New paleomagnetic results show that the ancient magnetic field intensity changed from 4.5 to 8 uT during the cooling of a 5 meter thick lava flow erupted during a geomagnetic reversal 16.2 million years ago. The lava flow ... -
Magnetic Stratigraphy and Tectonic Rotation of the Lower Miocene Rincon Shale (Saucesian Foraminiferal Stage), Santa Barbara County, California
(1999-01-01)The foraminifera from the Rincon Shale in Ventura and Santa Barbara counties, California, were the original basis for the Saucesian Stage of Kleinpell (1938). The Saucesian was originally correlated with the early Miocene, ... -
Magnetic Stratigraphy of the Upper Miocene Montesano Formation, Olympic Peninsula of Washington: Implications for Miocene Molluscan Biostratigraphy
(1999-01-01)The Montesano Formation in the Wishkah River near Aberdeen, WA, was the original basis for the late Miocene "Wishkahan" and "Graysian" molluscan stages of Addicott (1976). Yet the precise age of these formations has long ... -
Paleomagnetism Tectonic Rotation of the MIOCENE OBISPO Formation, Western Santa Barbara County, CA.
(2004-01-01)This is a paleomagnetic study on the Obispo Formation in the coastal region between Santa Barbara and San Luis Obispo. In this area lies the Santa Maria basin, which contains many faults, including the Santa Ynez fault, ... -
Magnetic Stratigraphy of the Eocene-Oligocene Transition in Northwestern Oregon
(1998-01-01)The Keasey Formation in Northwestern Oregon contains one of the most complete geologic records of the Eocene-Oligocene transition in the Pacific Northwest. Samples from this sequence of sedimentary rocks were collected in ... -
Paleocene Silverado Formation, Orange County, California
(1999-01-01)The late Paleocene Silverado Formation of the Santa Ana Mountains in Southern California is one of the few Paleocene sedimentary units in the West Coast. Up to 1700 feet thick, it records a marine transgression from ... -
Magnetic Stratigraphy of The Madre de Dios Formation (Miocene-Pliocene) in the Peruvian Amazon Basin
(2008-01-01)Deposits from the banks of rivers in the Peruvian Amazon basin have already produced a gomphothere mastodont below an Ar/Ar date of 9.01 Ma, making it significantly older than the closing of the Panamanian land bridge at ... -
Magnetic Stratigraphy of the Miocene Round Mountain Silt and Olcese Sand, Bakersfield, California
(2003-01-01)The Round Mountain Silt and the underlying Olcese Sand, northeast of Bakersfield, California, are famous for their large collection of marine vertebrates from the Sharktooth Hill Bonebed and fossil mollusks from both units. ... -
The Special Relationship: U.S./U.K. Relations since 1900
(2007-01-01)The ?special relationship? between the United States and the United Kingdom is arguably the most powerful cultural, political, and military union of any two countries in history. It has, however, been a long road to ... -
Magnetostratigraphy of the Lower Miocene Sespe-Vaqueros Formations, Santa Ana Mountains, Orange County, California L.L. Donohoo
(1998-01-01)The nonmarine redbeds of the Sespe Formation and the overlying gray marine sandstones of the Vaqueros Formation are widespread in southern California, and in most places yield Eocene and Oligocene mammals and molluscs. ... -
Effects of Pollution Hotspots, Education and Income on Birthweight in California
(2005-01-01)New Geographic Information Systems (GIS) analysis reveals a correlation between pollution hotspots in California and zones of high percentage of low-birthweight babies. The data reveals that both data sets are spatially ... -
Magneto Stratigraphy of the Coaledo Formation, Coos Bay, Oregon.
(1999-01-01)The Coaledo Formation, exposed in Coos Bay on the southern coast of Oregon, consists of 6000 feet of deltaic sediments, which filled the forearc basin in the Oregon Coast Ranges. This unit has yielded middle Eocene molluscs ... -
Paleomagnetism of the Miocene Tung Gur Formation, Mongolia, with a review of the Extinct Mustelid Sthenictis
(2003-01-01)I plan to reorganize the extinct genus of Sthenictis , re-evaluating as many known specimens are possible in order to rectify any problems within the genus. In addition I will describe a new species of Sthenictis from ... -
Geothermal Research in Iceland: Implications and Applications to the United States
(2003-01-01)I will be traveling to Reykjavik, Iceland for 5 weeks to learn about their new geothermal technology so that I may apply it to the southwestern United States. I will spend two weeks with the United Nations Geothermal ...
