Laboratory for Paleomagnetism and Environmental Studies

Laboratory for Paleomagnetism and Environmental Studies (IG PAS, Warsaw, Poland) hosts a set of the complementary equipment for palaeomagnetic and rock magnetic studies, that was gradually set up in years 1990-2018. The new set of equipment was added in 2018 for measurements of magnetic properties and laboratory experiments. The additional units for sampling and analysing of magnetic properties of environmental pollution (dust samplers) and portable magnetic susceptibility meters were also acquired. The whole lab extension was financed from undergoing EPOS-PL project and some additional lab preparation was also finished thanks to other Polish projects. At this moment our lab is the best equipped laboratory in Poland as the main Polish paleomagnetic facility. The lab is extensively used by two research groups within the department of magnetism – paleomagnetic team and environmental magnetism team. In last years we have given laboratory support to 6 PhD students as well to a few MSc student from collaborating universities. We also serve with analyses to other Polish and European research centres. Several projects were dealing with environmental and paleomagnetic studies at Spitsbergen. Paleomagnetic infrastructure is housed in two low magnetic field cages:

• one with 755–1.65 2G Enterprises cryogenic magnetometer DC SQUID with AF degausser, a new MMTDSC furnace and MMTD1 furnace with controlled atmosphere option available and pTRM available) and a new MMPM10 pulse magnetizer;
• the other with a new JR6 spinner magnetometer, LDA3a/AMU1a and a new LDA5/PAM1 Alternating Field Demagnetizer/ Anhysteretic and Pulse Magnetizers and MMTD-80 furnace for thermal demagnetization.
• separate spaces outside low -field cages are provided for a new KLY-5A/CS-4/CS-L, susceptibility bridge, MFK1-FA - susceptibility bridge, KLY-3/CS-3/CS-L Susceptibility bridge and KLY2 Susceptibility bridge;
• lab rooms for hysteresis properties are equipped with Micromag AGFM 2900-02, AVFTB Balance , Molspin VSM Nuvo
• additional stands are equipped with STEPS III apparatus for measurements of isothermal remanence (TUS, Poland) and Bartington susceptibility meters (MS2 and MS3).
• the lab area is also supported by the drilling/cutting room, samples preparation area, weight balances, binocular microscope.
• The set of 6 dust samplers for PM10, PM2.5, PM1 and TPM is used to collect the filters for magnetic properties of collected dusts in several locations. In the lab we can conduct a wide range of experiments – step wise AF and thermal demagnetisation of palaeomagnetic samples, magnetic anisotropy studies (AMS, AARM, AIRM) for tectonic and paleomagnetic studies, monitoring of magnetic susceptibility and its frqency dependence for environmental projects (MFK-1). It is supported by the rock-magnetic experiments:
• hysteresis properties measurements and FORC at room temperature for very small samples – with AGM 2900, at a wide range of temperatures (up to 800°C) – with AVFTB and larger heterogeneous samples (VSM Nuvo);
• magnetic susceptibility vs temperature studies (KLY3S, KLY5) and magnetization vs temperature (AVFTB) as well as isothermal remanence vs temperature (STEPS3). Our laboratory can be a good place to perform a wide range of the experiments in one place, where it is easy to find a time slot for measurements, especially for early career scientists. It is planned to build here a foundation to integrate other Polish laboratory groups (in case of paleomagnetic and environmental magnetism groups - Warsaw, Lublin, Zabrze).
