Description of the Sedimentary Paleomagnetism Laboratory
The research performed in the Sedimentary Paleomagnetism Laboratory of ISMER (Rimouski) uses the various magnetic properties of sedimentary sequences to reconstruct variations in Earth’s magnetic field, establish high resolution chronostratigraphy, and develop natural hazards and paleoclimatic proxies for the Quaternary. The laboratory is equipped with a 2G-Enterprises u-channel cryogenic magnetometer, allowing the continuous and high resolution measurement of the NRM (Natural Remanent Magnetization), ARM (Anhysteretic Remanent Magnetization), IRM (Isothermal Remanent Magnetization), and SIRM (Saturated Isothermal Remanent Magnetization) and magnetic susceptibility. The laboratory is also equipped with an alternating force gradient magnetometer to determine the magnetic mineralogy and granulometry, as well as a GEOTEK MultiSensor Core Logger to determine the physical properties of sediment cores, a spectrophotometer for quantifying the sediment color and a SmartCIS core scanner for continuous digital photography of core sections. The laboratory is also equipped to perform geophysical surveys and diverse core sampling in marine and lacustrine environments. Finally, grain size analysis can also be performed in the particle analysis laboratory.
