Dr. Stephen A. Klssin, B.Sc., M.S., Ph.D. Academic Background; Post Doctoral Fellow, McMaster University 1973 N.R.C. Post Doctoral Fellow, CANMET, Department of Energy, Mines and Resources, Ottawa 1974-75 Assistant Professor, Department of Geology, Lakehead University since 1975. My activities last summer began with the GACMACGEGCGU (basically. Geological Association of Canada Mlneraloglcal Association of Canada) meeting in Vancouver in late April. As well as presenting a paper on the new mineral cernyite, Cu CdSnS , I attended a field trip to the southeastern B.C. lead-zinc deposits. My particular aim was to collect specimens from the Sullivan Mine, with the view of examining the tin mineralogy and pyrrhotite-sphalerite geobarometry. On my return to Thunder Bay, I was involved with the 23rd Annual Meeting of the Institute of Lake Superior Geology, hosted by the Department, in the capacity of Technical Sessions Co-Chairman. I also attended the Mattabi field trip as a supernumary. For the remainder of May, I worked on the preparation of journal papers and some geological field problems in the Rabbit Mountain Mine area. My efforts were interrupted by the birth of my daughter, my second child, on May 31st. After two weeks at home, I returned to the University to work on another journal paper on stannite and other tin-bearing sulphide minerals. Continued study on tin-bearing sulphide minerals led me to the appreciation that two previously undiscovered species exist. One is the cubic form of stannite, normally tetragonal Cu 2 FeSnS , while the other is the iron analogue of kesterite, Cu 2 ZnSnS , which is also tetragonal, but has a space group which differs from that of stannite. In the latter part of August, I spent some time in the field mainly in the reconnaissance study of silver mines in the Rabbit Mountain area. As well, I made a trip to Ottawa to use the facilities at CANMET in order to investigate the two new minerals mentioned earlier and continue some aspects of research on the synthetic system Cu 2 FeSnS -Cu 2 ZnSnS 4 . After all this, I found that the summer was suddenly gone. F 1

Dr. R. Garth Platt, B.Sc.. Ph.D. Academic Background; Visiting Professor, University of Copenhagen, Denmark, 1969-70 NRC Postdoctoral Fellow, University of Western Ontario, 1970-71. N.E.R.C. Research Fellow and Staff member. University of Edinburgh, Scotland, 1971-74. Assistant Professor, Lakehead University, since 1974 The summer season began and ended with organized field trips to the Coldwell Alkaline Complex in N.W. Ontario. The early summer field trip was organized for the 23rd Annual Meeting of the Institute on Lake Superior Geology. A guide book was prepared for the occasion. The late summer trip saw a group of hardy students (some students claimed it snowed - fertile imaginations), studying the complexities of North America ' s largest alkaline complex and the rigours of life on the North Shore of Lake Superior. In between these events, serious research was continued on the pet- rology of the Coldwell Alkaline Complex with particular emphasis on the neph- eline syenites and the dike rocks associated with the intrusion. In addition, preliminary investigations of the Keweenawan Osier Volcanics of Northwestern Ontario were undertaken. The department ' s research boat was often seen braving the waters of Lake Superior with Dr. Platt in command and Dr. Mitchell navig- ating. Dr. Mitchell ' s navigation was so bad that the beginning of July saw us both on Bathurst Island in N.W.T.. This trip, under the auspices of the Polar Continental Shelf Project, was made to initiate studies into the geology and petrology of the Freeman ' s Cove Alkaline Volcanic Suite. This suite, con- taining as it does, nephellnites, basanites and phonolites is unique to the Canadian Arctic and its study will provide us with valuable information about the geological history of the area.

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
