Zircon and Accessory Phase Laboratory (ZAPLab)
Dr. 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.

Support Facilities & Resources

Earth Sciences Department Geoscience Collections
Samples from the Suffel, Dana, or Meteorite Collections described below are available by request for research, display, teaching or outreach activities. Please contact our Geoscience Collections Curator at geocollections@uwo.ca.

The Suffel Collection
The Suffel Collection 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 40,000 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 by loan agreement with the provisio the borrower provides an electronic copy of any data acquired and recognition in subsequent publication. 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. However, due to space limitations, we are selective in the types of specimen donations that we accept at this time.

The Earth Sciences Department at Western also annually awards the G. Gordon Suffel Fellowship for Graduate Studies in Applied Economic Geology to graduate students in a Master's or PhD program in Geology who have selected a thesis topic in applied economic geology, based on academic achievement and research merit. The recipient may receive this fellowship for up to three years, dependent upon performance and satisfactory progress. The student(s) selected will give a lecture to the Earth Sciences Department during the second term of the award, describing their research; and is required to assist in curating the Suffel Collection.

Dana Mineral Collection
The Dana Collection is a global suite of research quality mineral specimens that was first developed by Dr. G. Gordon Suffel and was later curated by Dr. Roberta Flemming. The collection, named after Dana's system of mineralogy, was developed to include the highest quality mineral specimens from the Suffel Collection to be used for both research and display. Subsequent donors have added to the Dana Collection, providing a wide range of mineral species and varieties for use in research by graduate students, faculty, and other academics, by loan agreement. The collection currently contains upwards of 8000 specimens from hundreds of deposits worldwide. The largest individual donor to the Dana Collection is Arnim Walter, with his mineral donations constituting almost half of the collection. Being an avid mineral enthusiast and professional photographer, Arnim spent his life touring, photographing and collecting spectacular mineral specimens from mines around the world. There are several displays containing Dana Collection minerals in the Department of Earth Sciences at Western. These minerals 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
The Western Meteorite Collection is an approved institutional repository of the Meteoritical Society. As Canada's leading research centre for planetary science and space exploration, Western is home to a collection of more than 250 meteorites that are available for researchers and students. The Western Meteorite Collection contains research type specimens including signature Canadian observed fall meteorites such as Dresden (1939), Tagish Lake (2000) and Grimsby (2009). This collection is primarily housed and displayed in the Biological and Geological Sciences Building. 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.

Western Paleontology Collection
The Western Paleontology Collection is a suite of fossils consisting of all the major invertebrate phyla, with some bacterial, protist, plant, and vertebrate specimens. The collection is primarily used for teaching, accumulated over many decades from purchases, donations from fossil collectors, and contributions from the research collections of department faculty. The fossils are mostly from well-known fossil sites in North America, Europe, and other parts of the world. Teaching fossils are kept in the teaching laboratory in the Biological and Geological Sciences Building.
