Paleomagnetism and Rock Magnetism Laboratory

The newly completed Paleomagnetism and Rock Magnetism laboratory, including a low magnetic field induction space designed and constructed by Dr. Gary Scott of Lodestar Magnetics, is about 2,600 sq. feet in footprint, and includes an attached sample preparation/wet chemistry laboratory, equipped with a fume hood, and an attached meeting/office space area for graduate and undergraduate students. The laboratory includes all non-magnetic furniture and cabinetry installed by Dr. Gary Scott and colleagues in the low magnetic field space. The workhorse instrument for all remanence measurements is a 2G Enterprises Model 760R horizontal access, three measurement axis (DC SQUID) superconducting rock magnetometer, equipped with DC SQUIDS and superinsulation. A fully automated specimen handling system is interfaced with an online alternating field (AF) demagnetizer capable of reaching peak inductions of 160 mT, allowing for automated demagnetization of specimens. We have initiated the purchase of a new, pulse-cooled magnetometer from 2G Enterprises, with anticipated delivery in early 2013. AGICO JR-5 and AGICO JR-6 spinner magnetometers allow for the remanence measurements in both automated and static mode. Thermal demagnetization is conducted using Shaw (MMTD), and three ASC (TD48) furnaces, a Schonstedt (TSD-1), as well as a home built large-volume, three heating zone furnace capable of heating/cooling in an inert atmosphere. A large-volume furnace is capable of conducting long-term, elevated temperature magnetic viscosity experiments in a controlled atmosphere. The laboratory includes two ASC impulse magnetizers, with the full range of coil sizes. Two home built impulse magnetizers capable of peak DC induction of 1.3 T and 3.4 T and a horizontal Curie balance for measuring saturation magnetization as a function of temperature in an inert atmosphere. An additional, home built impulse magnetizer, capable of reaching about 9 T, is currently being tested. Two ASC D-2000 AF demagnetizers provide peak field values of 200 mT and are capable of imparting anhysteretic remanent magnetization (ARM) and partial ARM with DC fields up to 1.0 mT. A D-Tech coil interfaced with an externally tuned Schonstedt GSD 1 AF demagnetizer also allows for AF demagnetization and ARM acquisition. Chemical demagnetizations are carried out in a fume hood environment in the laboratory. The leaching and drying of specimens is carried out in a field-reduced environment (less than 300 mT) in the fume hood. Kappabridge KLY-3S, KLY-4S, and MFK1-FA automated susceptibility systems allow bulk and anisotropy of magnetic susceptibility measurements to be made in both static and automated modes. The KLY-3S and MFK1-FA susceptibility units are interfaced with a CS-4 furnace assembly for measuring susceptibility as a function of temperature in an inert atmosphere. The laboratory also has over ten sets of mu-metal shields of different volumes and geometries, to provide very low magnetic field environments for different purposes. We are equipped for all aspects of field sampling and specimen preparation, including four complete sets of drilling equipment and three dual bladed trim saws. An Olympus BX51TRF-5 transmitted light/reflected light microscope, equipped with a dedicated DP72, 12.8 mp digital camera. A Princeton Instruments AGM/VSM, equipped with a high temperature furnace assembly, acquired by the Physics Department in 2010, has been transferred to the Geosciences Department, and a space remote from the Paleomagnetism Laboratory houses the magnetometer and internal water chiller system. The Physics Department at UT Dallas maintains a Quantum Designs Magnetic Property Measurement System and this is available for use by the PI and students. The UT Dallas Paleomagnetism Laboratory has dedicated field vehicle.
