Palaeomagnetic laboratory

CAGE


The Cage

The NGU CAGE is designed for palaeomagnetic research requiring that magnetic measurements and demagnetizations are performed in a low magnetic field environment. Provides a low field environment just like a mu-metal room, but allows the magnetic fields, due to the equipment, to escape and therefore does not enhance them. X-Y-Z field components are independently adjusted to permit moving magnetic anomalies without moving the equipment. The field in the cage is monitored with 3-axis magnetometer and automatically compensated.

JR-6A


The JR6A

The JR-6A Spinner Magnetometer is an advanced features instrument to measure remanent magnetization in rock specimens.

Automated thermal demagnetizer MM-TD-60


The TM60

Advanced features ensure precise temperature control and near zero magnetic field environment for high quality thermal demagnetization.

2-axes alternating field tumbler


The Tumbler

NGU alternating field demagnetizer. 2-axes tumbler - maximum field 100mT (constructed by T. Totland).

Curie balance


The Curie Balance

NGU Curie-balance (designed and constructed by O. Totland) used to identify magnetic minerals.

Impulse magnetizer


The IM-10

The ASC Model IM-10 instrument generates short duration magnetic fields of up to 11 KGauss within the sample coil. It enables a variety of high-field magnetic studies to be conducted on geologic samples without the need for a large electromagnet.

MS2


The MS2

The MS2 system is the international standard for the measurement of magnetic susceptibility in environmental sciences. The MS2 meter is a portable instrument with sensors for field and laboratory use.

Susceptibility/Temperature System


The sus/temp system

For the measurement of the magnetic susceptibility of 2.5ml samples over the temperature range -200°C to +900°C. It is used in the investigation of magnetic mineralogy and grain size and for the determination of Curie transition temperatures.
