Geology & Geochemistry Facilities

The Powder X-ray Diffraction (pXRD) and Micro X-ray diffraction (μXRD) Laboratory provides facilities for powder and in situ mineral analysis based on crystal structure. The laboratory has a conventional Rigaku Powder diffractometer and a Bruker D8 Discover microdiffractometer with a 50-500 μm beam diameter, 2D area detector, automated XYZ sample stage and microscope-camera system, for in situ X-ray analysis of discrete mineral grains in rock slabs, probe mounts or polished sections.

The Experimental Mineralogy Laboratory engages in mineral synthesis and characterization.  Facilities include high-temperature furnaces and sample preparation equipment. Crystal structures are refined using Topas Rietveld crystal-structure refinement software, and cation ordering is determined by solid-state NMR using NUTS and DMFIT software (NMR spectrometers are located in Chemistry and at the Ultrahigh-field Solid State NMR facility in Ottawa).  

The ZAPLab is an electron nanobeam facility (www.zaplab.uwo.ca) for determining the orientation and chemical nanostructure of materials. It began operation in summer 2010, and, after two years of partial department support, a full-time technician position is now fully supported by ZAPLab industry clients and research collaborators. Moser’s group is expert in the application of Electron Backscatter Diffraction (EBSD), Cathodoluminescence (CL) and X-ray spectroscopy (EDS/WDS) techniques to micro minerals used for isotopic dating of earth, solar system and resource-forming events. Collaborative work is resulting in equal success in applying ZAPLab tools to the analysis of ores, environmental and manufactured bio/materials. Graduate student training in the facility is continuous and comprehensive, attracting students from across the Western community and the region.  Apart from Moser’s group of 5 graduate students, roughly triple that number from the Dept. of Earth Sciences have conducted research in the facility so far. Moser also co-supervises the research of graduate students in the Departments of Geography, Biology, Chemistry and Engineering/ Surface Science Western and is building collaborative links with the Center for Advanced Materials and Biomaterials Research (CAMBR) at Western and the Canadian Centre for Electron Microscopy at McMaster University. A growing number of graduate students from surrounding universities including University of Toronto, ROM, Waterloo, Carleton, Queen’s and McGill are also actively conducting research at the ZAPLab. This new facility is proving to be a valuable component of fundamental materials science research and training at Western.

The structural geology and fabric simulation lab has three sets of equipment for integrated research on deformation structures in Earth’s continental crust.  The computational set contains 4 state-of-the-art computer workstations, associated commercial (FLAC2D and FLAC3D) and self-developed software (self-consistent MOPLA, the Self-Consistent MultiOrder Power Law Approach based on micromechanics), and peripheral devices for modeling and visualization of natural deformation and fabric development.  The digital mapping set contains 3 state-of-the-art Trimble GeoXH handheld mapping devices and a field vehicle (Toyota Tacoma) for large-scale high-precision field geological mapping.  The microstructure analysis set contains 4 microscopes (Nikon, Leitz, Leica), 2 Leica macroscopes, and attachable universal and mechanical stages for fabric characterization in rock thin sections.  Additionally, there is an EBSD camera installed in ZAPLab for textural analysis at the micron scale.  

The A.D. Edgar Laboratory for Electron-Probe Microanalysis houses an electron microprobe that is fully automated by a state-of-the-art computer system. Chemical microanalyses of thick samples, thin films and particles are possible and high-resolution digital electron and X-ray images can be acquired. The lab also houses a Scanning Electron Microscope.

Funded by CFI, this computational infrastructure is housed within the Department of Earth Sciences (BGS Rm 059 and Rm 179). The aim of the CGL is to implement research projects in computational geophysics, leading naturally to the development of a parallel computational framework in geophysics. The infrastructure consists of the following components: 1) a computer mini-cluster (8 nodes – 96 processors), a server node, a storage/backup node; 2) a software suite for parallel code development, data analysis, and visualization. Each computer workstation has specific software installed for modelling, analysis, and interpretation of natural and synthetic data (Matlab, Gedco Vista, Mathematica, OriginPro, Comsol Multiphysics). They also have appropriate software development tools installed, including compilers for C/C++, Fortran with MPI library implementation (Intel Compiler and Cluster Toolkits, NAG Libraries) for the development of in-house serial and parallel codes. Once executable codes are ready, large-scale testing and production runs are submitted to SHARCNET clusters (a consortium of Canadian academic high performance computers), fully leveraging the computing power of these parallel facilities.

Environmental Geosciences

The hydrogeology laboratory is subdivided into a computer room and a water / porous media assessment room.  Two servers in the computer room support ground water modelling studies with networked licences for FEFLOW FMH3 and several other programs including SUTRA, SUTRA-ICE, MODFLOW, AQTESOLV Pro, Tecplot, Surfer, MATLAB, ArcGIS.  The assessment room allows for the characterization of surface and ground water flows through equipment such as SonTek 3D FlowTracker ADV, Price and Pygmy current meters, depth (DH-48) and point integrated (DH-59) sediment samplers, permeameters, conductivity meters, time-domain reflectometers (TDR100), thermistors, pressure transducers, all supported by Campbell Scientific data loggers (CR1000, CR10X). The lab is linked with the Earth Sciences Biome – a unique two-level climate chamber in which soil monoliths (up to 1m diameter x 3m high) can be studied under replicated environments mirroring Arctic tundra to modern agricultural fields.
