SRM-755 Superconducting Rock Magnetometer

Magnetómetro

The SRM-755 Superconducting Rock Magnetometer is equipment that allows the determination of the natural remanent magnetization of sediment and rock soundings, as well as discrete samples automatically, in terms of intensity and direction (magnetic moment, magnetization) and direction (spatial location vector through declination and inclination values).

Magnetómetro
Instrumental Facilities

Magnetómetro criogénico superconductor SRM-755 (2G Enterprises)

Applications
  • Determination of natural remanent magnetization (NRM)
  • Determination of antihysteretic remanent magnetization (ARM)
  • Determination of isothermal remanent magnetization (IRM)

Very useful in the analysis of sediments and rocks in studies of palaeomagnetism and environmental magnetism, archaeomagnetism, pollen, climate change, geochronology, stratigraphy, tectonics..

Sample requirements
  • U-channels are up to 1.50 m long.
  • Discrete samples (≈10 cc)
  • One request will be made for each survey.
  • Samples will be delivered to the Core Scanning Laboratory (Floor -2, CACTI Tower Annex). Please check with the Service to confirm sample reception hours.
  • Sample collection period after analysis: 1 month
