Investigation of a marine magnetic polarity reversal boundary in cross section at the northern boundary of the Kane Megamullion, Mid‐Atlantic Ridge, 23°40′N

Near‐bottom magnetic field measurements made by the submersible Nautile during the 1992 Kanaut Expedition define the cross‐sectional geometry of magnetic polarity reversal boundaries and the vertical

Plate Reconstruction: Mathematical-Physical Framework and Selected Case Studies

Engen, O., 2000, Plate reconstruction; mathematical-physical framework and selected case studies [term paper]: Oslo, University of Oslo, 25 p. Literature treating plate reconstructions has been

Identification of marine magnetic anomalies based on the sliding window curve similarity method

Abstract Marine magnetic anomalies play an essential role in plate tectonics and geodynamics. The conventional method to identify marine magnetic anomalies is to visually compare synthetic and

Nature of the Cuvier Abyssal Plain crust, offshore NW Australia

Magnetic stripes have long been assumed to be indicative of oceanic crust. However, continental crust heavily intruded by magma can also record magnetic stripes. We re-evaluate the nature of the

A new contribution to the geology of the Egyptian Red Sea shelf using geophysical data

The study examines the Egyptian Red Sea shelf and throws more light on the structural set‐up and tectonics controlling the general framework of the area and nature of the crust. Herein, an integrated

The Anna Karenina principle: A way of thinking about success in science

The Anna Karenina principle is introduced as a way of thinking about success in science in three central areas in (modern) science: (a) peer review of research grant proposals and manuscripts, (b) citation of publications, and (c) new scientific discoveries (recognition as a scarce resource).

Low-temperature alteration and magnetic changes of variably altered pillow basalts

SUMMARY Pillow basalt fragments from the East Pacific Rise, dredged during the Phoenix expedition, often show discoloured rims due to alteration. A suite of nine pillow basalts with such discoloured

Spatial Logic In Paleogeography and the Explanation Of Continental Drift

Abstract The scientific methods employed in paleogeography have followed two distinct logics. Spatial logic accepts morphology, spatial distribution, and spatial association as primary evidence of

Geochronological Applications Development of the Geomagnetic Polarity Time Scale

  • Geology
As discussed in Chapter 1, geomagnetic secular variation exhibits periodicities between 1 yr and 10 5 yr. We learn in this chapter that geomagnetic polarity intervals have a range of durations from



Magnetic Correlation in Volcanic Districts

Abstract Alternating zones of normal and reverse natural permanent magnetization, each comprising about twenty-five flows, have been found in the Tertiary and Quaternary plateau basalt series of

Total magnetic field surveys between New Zealand and the Ross Sea

During the summers of 1958–1959 and 1959–1960, total magnetic field surveys were made with ship-towed nuclear spin magnetometers between New Zealand and the Ross Sea. The total field contours are

Magnetic properties of the basalt in hole EM 7, Mohole project

The average direction of the remanent magnetization of the basalt layer at the bottom of hole EM 7 is inclined 36° above the horizontal, indicating that the layer is reversely magnetized. Detailed

Magnetic anomaly over Mohole drill hole EM7

Cox and Doell [1962] have found the basalt samples from hole EM7 of the experimental drilling phase of the Mohole project to be reversely magnetized with respect to the earth's magnetic field. This

Magnetic survey off the west coast of North America

A ship-towed magnetometer survey of an area 250–300 miles wide off the foot of the continental slope along the coast of California has revealed a narrow pattern of anomalies of about 400 gammas

Magnetic Anomalies over the Mid-Atlantic Ridge

THE intensity of the Earth's magnetic field over the Atlantic Ocean has been measured on a number of flights organized by the Department of Mines and Technical Surveys of Canada and also under
