The laboratory performs in situ U-Pb dating and trace element analysis of mineral grains and other geological samples. The work flow in the laboratory is organised by the laboratory manager in collaboration with the technical staff. Samples are usually prepared in GEUS' sample preparation laboratories, but external users may bring ready prepared samples (please consult with the laboratory manager about details). It may be possible for external users to carry out their own analytical work - including subsequent data reduction - after receiving appropriate training by the laboratory staff.

Key Instruments
Element 2 Sector Field Inductively Coupled Plasma Mass Spectrometer (SF-ICP-MS) coupled to a New Wave UP 213 laser ablations system (LA).

Restrictions on access
All methods and instruments require detailed instruction and training, so users of the laboratory should preferably be associated with the department over a period of time. The laboratory has extensive experience in training students in using the methods and equipment.

Rates
Contact the laboratory for information on prices.

Where
Department of Petrology and Economic Geology, area 3, room 2-335.
