The laboratory's scientific mission is to apply stable (O, C, H and S) isotope geochemistry to the origin of rocks and ore deposits and to selected problems in other scientific endeavours of Earth Science.

Driven by scientific questions, the laboratory undertakes the development of new technology and/or methods that expand current avenues of research, or bring about significant improvements in existing analytical techniques and/or results. A good example is the field of microanalysis, and the developmemt of MILES (Micro-Isotopic Laser Extraction System).

The governing mission is to be a world leader in both areas, with a world-class facility.

The Light Stable Isotope Laboratory is supported by two Finnigan 252 mass spectrometers, one interfaced with a Carlo Erba elemental analyzer and automated Gas Chromatograph sampling equipment. State-of-the-art extraction facilities include MILES (a Micro-Isotopic Laser Extraction System), and high-vacuum and GC-assisted preparation lines.

Petrographic and binocular microscopes, a micro-drilling station, a research analytical balance, micro-analytical balance, and a computer work/graphics station are available in the laboratory. Pulverizing and other sample preparation facilities are in the Geological Sample Preparation Laboratory.

Oxygen, Carbon, Hydrogen and Sulphur isotope analyses are undertaken of rocks, minerals, fluid inclusions, waters, gases, and selected organic materials. In-situ, microscopic-domain isotopic analysis is currently performed on sulphides. A wide range of techniques developed, or used by the laboratory permit isotopic investigation of many different materials.

The above mission is achieved by initiating relevant projects and by collaboration with colleagues from the GSC, industry, and academia from around the world. The projects variously involve basic and/or applied science aligned with GSC goals and objectives. Examples include: Sullivan Project, Kidd Creek Project, CAMIRO VMS Project, etc.

Training has been provided to visiting scientists from around the world (e.g., Australia, Brazil, Netherlands, Germany, Canada, and the United States), to graduate students and post-Doctoral Fellows, and is available to any interested scientist as staff time and resources permit.

Approximately 25% of the annual effort of the laboratory is devoted to providing analytical service to colleagues within the GSC for routine isotopic analyses, following consultation with laboratory scientific staff.

• operation and maintenance funding, and capital funding are assigned on an annual basis according to GSC internal funding procedures
• additional funding has been derived from SPA research agreements for collaborative research with industry (e.g. Falconbridge; Western Mining Co; CAMIRO-GSC joint research project) and academic institutions. Costs are shared with these research partners.
