1 Howard Poulsen. B.Sc. (Physics), B.Sc. (Geology ' ) Background; Exploration Geophysics 1961-71 High School Teacher 1968-69 Research Assistant (for J.M, Franklin) 1972-75 Laboratory Demonstrator at Lakehead University since 1975 In addition to the ongoing analytical work of the Geochemistry Lab, the past summer provided for me three geological highlights; the annual meeting of the Institute on Lake Superior Geology in May; the visit of three foreign students at our Department; and a major retrieval of soft sediment cores from Lake Superior. My contribution to the LSI meeting centered around a 2-day post- conference field trip to the Mattabl and NBU massive sulphide deposits. The trip, which entertained 46 geologists from all parts of North America, stressed the geological setting and genesis of the deposits based on the research of James Franklin of the Geological Survey of Canada. Jim and I spent a good deal of time organizing the trip in conjunction with the mine geologists as well as preparing a trip guidebook which summarized much of our research work at Sturgeon Lake carried out in the interval 1972-75. The summer saw the arrival of three graduate students from Geologisch- Paleontologisches Institut, University of Hamburg, West Germany. Frank, Rudi and Claus had come to Thunder Bay to study iron formations as part of their graduate thesis requirements at Hamburg and informally allied themselves with our Department for the summer. Their stay here provided many interesting insights into geological education in Germany in com- parison with the type of programme offered by our own University. Of particular interest was their reason for coming to Canada for field work; they had the sinking feeling that possible hundreds of geologists had already worked on most of the exposures in Germany. Our own fourth year students can take heart from this, considering the novel field aspect of most of their bachelor ' s theses. One particularly fine sunny day found me aboard a barge in the middle of Thunder Bay harbour as part of a crew Involved in the retrieval of four 50 foot piston cores of lake bottom sediment. The project was headed by Dr. Mothersill who is using the materials collected to study various aspects of the evolution of Lake Superior during the past 12,000 years. Although this project was of short duration ( one day ), it was most enjoyable and I didn ' t even get sea sick. 1 v '

Roy J. Shegelskl, H.B.Sc., M.S., Ph,D. (pendin g) Academic Background; University of Toronto 1973-77 Ph.D. pending Lecturer at Lakehead University since 1976 This summer was spent investigating mafic volcanic terrains in the Northwest Territories. The particular areas of study were the Nowyak Lake area and the Griffin Lake area which are within 60 km of each other and located in NTS sector 65G. The areas are located within the Churchill Pro- vince and are Archean in age. The predominant lithologies of the areas include pillowed and massive basalts with subordinate amounts of ultramafic flows ( some showing splnifex textures), banded and laminated oxide facies iron formations, chertz sulphide facies iron formations and minor felsic pyroclastic and volcanoclastic tuffs and sediments. These areas were being investigated for massive sulphide potential. Results of the follow up to geophysical airborne and ground surveys in one of the areas led to the de- lineation of several favourable zones of nickel sulphide mineralization, in fact results are so encouraging that I cannot talk of them I The summer was relatively wet; the black flies were bad but the crews were great and included two able assistants from L.U.; R. Hall and B. Schneiders . 1

Rona Id Bennett Ron was the Chief Laboratory Technician at the Grant Institute of Geology, University of Edinburgh from 1936 to 1967. His research includes many kinds of technical approaches to Ph.D. studies. He has been the Principal Technician at Lakehead University since 1967. Ann Sumpter Ann was born and educated in England and emigrated to Canada in June 1967. She joined the staff of the Department of Geology at Lakehead University in July 1968. I Ann maintains all the requirements of the I first year teaching laboratory and manu- factures thin sections of suites of rocks for all the Department ' s teaching purposes, of students field trip collections and for the research projects of the Faculty members. Sam Splvak Sam was born in Port Arthur where he received his basic drafting techniques in high school and his geological training while in the employment (for 8 years) of a local mining company. He has been draftsman for the Science Department for the past 7 5 years. He maintains a fairly extensive map library (4500 geological maps), while his drafting time is largely devoted to preparing maps, overlays and drawings for use as teaching aids and research publications.
