The Paleomagnetism and Rock Magnetism Laboratory includes:
A 2G-enterprises super conducting rock magnetometer. This instrument measures the bulk magnetism carried by natural samples, including samples collected during coring programs, material that dates to the Archean, and meteorites. The magnetisation of these rocks is typically measured as a function of temperature (using one of our paleomagnetic ovens) or alternating magnetic field (using our in-line degausser).
A quantum diamond microscope (QDM). This cutting-edge instrument is one of two geo-QDMs in Europe, and is capable of imaging the stray magnetic fields emanating from samples with micrometre-scale resolution. As such, this instrument opens a new length-scale of material to rock and paleomagnetic investigation. For instance, this instrument is capable of measuring the magnetic romances carried by the individual grains in sedimentary rocks, so unlocks a suite of new material to reliable paleomagnetic studies.
Paleomagnetic ovens. The lab currently houses two high-precision ovens that are capable of demagnetising and remagnetising samples to high precisions. The lab will soon be receiving a new, state-of-the-art oven that will include atmospheric control, allowing samples to be heated in environments that minimise their alteration so that their remanences can be unlocked reliably for the first time. The aim is to apply this technique to lunar rocks, meteorites, and samples from the early Earth.
A kappabridge. This instrument is capable of measuring magnetic susceptibility as a function of both low and high temperatures, as well as room temperature.
