Department Classrooms

The Department of Earth Sciences controls two computer labs, four teaching labs, a seminar room and a conference room in BGS.

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.

  • Experimental Mineralogy Laboratory (Roberta Flemming)

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).  

  • Zircon and Accessory Phase Laboratory (ZAPLab) (Desmond Moser, Director)

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.

  • Computational Geophysics Laboratory (CGL)

Robert Shcherbakov, Gerhard Pratt

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.

Support Facilities & Resources

  • The Suffel Collection

    The Suffel Collection (Norm Duke, curator) is composed of ore suites and was initiated at Western by Dr. Rod McDonald about 1940.  In 1946-47 Dr. Gordon Suffel began to reorganize and add to this nucleus. By the early 1970s gifts from faculty, students and donations by interested mining companies amounted to about 15,000 catalogued specimens. Subsequent to his retirement in 1975 the Suffel Collection has been augmented primarily by sampling on student/faculty fieldtrips and from rock suites utilized in theses on the geology of mineral deposits. This latter phase of collection was initiated by R.W. Hutchinson, has been carried on by R.W. Hodder and most recently by N.A. Duke. The collection now consists of more than 200,000 catalogued samples. Although most of the original suites were collected from ore deposits in North America, the collection now has a much more international scope.

    The Suffel Collection is a valuable resource for mineral deposit research, from conventional metallogenic studies to investigations into the susceptibility of differing ores to weathering. Having a range of sample material from widely differing deposit types is becoming increasingly important as many of the mines represented in the collection are now closed and inaccessible. More than other specialties within the Earth Sciences, comparative studies are central to research into the subtle differences shown by broadly similar deposit-types. Housing such a large number of ore suites under one roof is unique in North America.

    The samples are available for teaching, research and display purposes. Several hundreds have sections suitable for microscopy. The collection is more freely available to senior undergraduate and graduate students, faculty and alumni. Your interest in this collection is earnestly solicited. We encourage anyone having the opportunity to collect suitable material to do so and donate it to the department, along with an appropriate description and details of location and date.

  • Dana Mineral Collection (Curator, Roberta Flemming), named after Dana’s System of Mineralogy, consists of over 3800 mineral specimens, first collected by Professor Gordon Suffel. Several subsequent donors have added minerals to the collection. These minerals comprise several displays in the department and may be borrowed as research specimens with the proviso the borrower provides to the Dana Collection an electronic copy of any data acquired, and recognition in subsequent publication.
  • Western Meteorite Collection, (Curator, Phil McCausland) The Western meteorite collection contains nearly 200 different meteorites, including large portions of several Canadian meteorite falls and finds such as the Tagish Lake carbonaceous chondrite, the Dresden H5 chondrite and the Southampton pallasite. The growing Western meteorite collection contains a wide variety of meteorites and meteorite types to facilitate research as well as teaching and outreach activities throughout each year. Samples for these activities are available by request to the Curator Phil McCausland, at pmccausl@uwo.ca
