Determining the position and thickness of the oil-water transition zone (OWTZ) in hydrocarbon reservoirs is important to reserve estimation and production planning. This paper describes a magnetic method of identifying this zone. High temperature sus

First-order reversal curve (FORC) diagrams are used increasingly in geophysics for magnetic domain state identification. The domain state of a magnetic particle is highly sensitive to particle size, about which FORC diagrams provide valuable informat

Complex magnetic domain structures and the energy barriers between them are responsible for pseudo‐single domain phenomena in rock magnetism, and contribute significantly to the magnetic remanence of paleomagnetic samples. This article introduces M

Long-lived magnetism in chondrite parent bodies

Autor: Shah, J, Bates, H, Muxworthy, AR, Hezel, DC, Russell, SS, Genge, MJ

We present evidence for both early- and late-stage magnetic activity on the CV and L/LL parent bodies respectively from chondrules in Vigarano and Bjurböle. Using micro-CT scans to re-orientate chondrules to their in-situ positions, we present a new

Direct visualization of the thermomagnetic behaviour of pseudo-single-domain magnetite particles

Autor: Almeida, T, Muxworthy, AR, Kovacs, A, Williams, W, Brown, PD, Dunin-Borkowski, RE

The study of the palaeomagnetic signal recorded by rocks allows scientists to understand the Earth’s past magnetic field and the formation of the geodynamo. The magnetic recording fidelity of this signal is dependent on the magnetic domain state it
