FACILITIES
The Department is well-equipped for
research with all of the standard research
tools expected in an Earth Science department.
It also has a variety of specialized research
equipment available, as summarized below.
Extraction lines for the preparation of carbonates, silicates, sulfates,
sulphides, phosphates, waters, and organic matter for the analysis of H, C,
N, O, and S isotope compositions.
A VG602 isotope ratio mass spectrometer for the routine analysis of H, C, N,
O, and S isotope ratios.
A state-of-the-art MAT 252 isotope ratio mass spec that is the most
sensitive and precise instrument on the market.
A laser-ICPMS (inductive coupled plasma mass spectrometer) that can resolve mass differences
of only .0001. This enable analysis of elements such as Li, B, F, K, Cl, Fe, As, Se, Au and others, which, because of mass interferences, are indistiguishable by most other systems in Canada.
Age-dating facilities based on the Argon-Argon dating method.
Age Range: 100,000 years and older
Suitable material: Hornblende, micas, and feldspars commonly are used, and some volcanic rocks and slates are suitable for analysis as whole rocks.
Conventional step-heating method: one AEI MS10 mass spectrometer with on-line computer data collection & analysis, connected to an ultra-high vacuum
argon extraction system using Lindberg tube furnace for the heating of sample.
Laser microprobe: one MAP 216 mass spectrometer, on-line computer data collection and analysis, and an ultra-high vacuum argon extraction system using either
a LEXEL 3500 argon laser or a resistance furnace for the heating of sample.
Large-capacity centrifuge (capable of subjecting two 0.5 kg models to
accelerations up to 20 000g) used in scale-model studies of tectonic
processes./li>
Models are constructed of analog materials such as Plasticine and
silicone putty.
The models measure about 75x125mm in plan and 3-20 mm thick.
The model ratio of length is typically 1:100,000 to 1:2,000,000 (1 mm
= 100 m to 1 mm = 2 km). In experiments at 4,000 g the time ratio is
typically about 1 hour = 10-20 Ma.
The models can be deformed in stages so that the progressive evolution
of structures can be monitored.
At the end of an experiment, the model can be cut into closely spaced
serial sections so that the internal 3-d geometry can be studied.
Processes investigated in the past include gravitational subsidence,
diapirism and laccolith intrusion. The current emphasis is on structural
development of foreland fold-thrust belts.
