GSO Paleomagnetics Laboratory


GSO Paleomagnetics Laboratory The Paleomagnetics Laboratory specializes in paleoenvironmental and paleoclimatic studies of sediments, as well as trace metal geochemistry of lacustrine, estuarine and marine environments. For paleoenvironmental and paleoclimatic studies, the lab is equipped with containing a complete suite of paleomagnetic and rock-magnetic equipment.		Analyses of: Magnetic properties of sediments; Trace metals; Grain size; Acid Volitile Sulfide;
Instrumentation includes: the largest magnetically shielded room in the world; two 2-G Enterprises cryogenic magnetometers, one for analyzing whole cores, and another for analyzing U-channel samples; a gradient force magnetometer, Bartington susceptibility meter and loop sensors in a variety of sizes, alternating field and thermal demagnetizers, and both a split- and whole-core Geotek Multisensor Core Logger.

Laboratory instrumentation for trace metal and grain size analyses of sediments includes: a Perkin-Elmer 4100ZL Graphite Furnace Atomic Absorption spectrometer, Elzone particle size analyzer, microwave and sonication sediment digestion systems, Simultaneously-Extracted Metals/Acid Volatile Sulfide (SEM/AVS) apparatus, and various small supporting equipment such as muffle furnaces, centrifuges, and balances. The lab is also equipped with an extensive selection of equipment for field collection of sediment grab and core samples from marine and lacustrine environments.
