Dr. M.W« Bartley, M.Sc., Ph.D. Backgroundj Lecturer University of Toronto 1938-40 Iron Ore Exploration since 1938 Steep Rock Iron Mines development 1940-48 Principal, Lakehead Technical Institute 1948-52 Honary Professor Lakehead University since 1971 President C.I.M. 1976 I am one of the fortunate people who has had a very rewarding ex- perience being involved with mineral exploration, mine development, mine operations and academic endeavours for almost forty-five years. My greatest reward has been the accumulation of many close friends and professional peers, young and old in many parts of the world. Nothing can take the place of friends in one ' s chosen field of endeavour because they are always a source of enjoyment and a limitless fund of information. I maintain that whatever success I may have had is not the result of what I know but rather who I know and can turn to for advice. After graduation from the University of Manitoba in 1934 and during subsequent post-graduate work I was employed by the Ontario Department of Mines during the field seasons and lectured at the University of Toronto during the academic year. During my final year of post-graduate work at Toronto I enlisted in the R.C.A.F. but was seconded to Steep Rock Iron Mines Limited to develop an iron mine in support of the war effort. I have remained in the field of iron ore exploration and development since that time. Interspersed was a brief period, 1948 to 1952 as Principal, Lakehead Technical Institute. My, involvement in the consulting field has been very pleasant and educational. My work has taken me to every Province except Prince Edward Island, to many of the United States, to the high Arctic and to several countries in South America, Asia, Europe and Africa. Each has been a new experience and I can recommend the life and the role to all graduates in geology. Since I have lost the desire to attempt fifteen to twenty mile daily mapping traverses my present endeavours are directed towards economic appraisals and evaluations of mineral deposits and mine de- velopment. These are exacting assignments, often fraut with frustration because of the vast bureaucratic maze which must be negotiated. I find that my few hours per week devoted to Instruction at Lakehead University is a welcome respite. I enjoy sharing my experiences with students who are so eager to learn and are so appreciative of assistance. I heartily recommend that all prospective geologists and those in allied sciences become members of professional associations. It is through these affiliations that you will gain professional stature and lasting personal satisfaction. I wish you success, satisfaction and many years of productive life after graduation.

Dr. Manfred M. Kehlenbeck, B.A., M.S., Ph.D. Academic Background; Visiting Professor, University of New Brunswick 1969-70 Teaching Fellow, Queen ' s University 1970-71 Assistant Professor, Lakehead University 1971- Chairman of the Department of Geology, Lakehead University since 1976. The western part of the Superior province is composed of a series of subprovinces which have become better known as belts. Among these structural subprovinces are the Quetico, Shebandowan, and Wabigoon belts. In the area north of Thunder Bay these belts are well exposed, and the rocks within them have been the substance of my research interest for the past six summer seasons. Although my interests range widely, I have become Increasingly more concerned with the spatial and temporal relationships of the rock types of adjacent belts. The Quetico Belt in particular, has held my fascination because it is bounded on the south by the Shebandowan belt and on the north by the Wabigoon belt and therefore offers a perfect target to study the relationships between three adjacent belts. Structurally the Quetico belt is characterized by linear and, to a lesser extent, planar elements which produce a dominant east-west grain. These same structural elements in the adjacent belts appear more varied in attitude except near boundaries with the Quetico belt where a zone of transition forms the changeover to the dominant east-west trend of the Quetico belt. Studies of the lithologies exposed in different belts have shown that essentially similar rock types occur in all the belts. The metamorphic history differs between belts so that the rocks tend to appear different at first glance. Relative abundances of rock types also vary from belt to belt as well as within a single belt. It appears certain that the structural characteristics are among the important criteria by which we can divide the western Superior province into subprovinces or belts. What now appears essential is to establish a tectonic framework which will explain the reasons for the observable structural differences in portions of the Archean crust. i;

Dr. Roger H. Mitchell, B.Sc., M.Sc., Ph.D. Academic Background; Lecturer in Isotope Geochemistry, University of Oslo, Norway, 1971-72. Assistant Professor of Geology, Lakehead University, 1972-76. Associate Professor of Geology, Lakehead University, since 1976. Field work this year commenced with a visit to the Moonshine Hills of Kentucky in search of the type locality of mica peridotite. The search was not a resounding success as the peridotite dikes are intruded into faults occupied by flourite veins which weather to a persistant glutinous red mud, thus hiding the igneous rocks. Six months later I still have some of the mud on my boots. Samples were found with the aid of gophers, despite such hazards as flourite mud, bloodsucking ticks, snakes, fields of poison ivy and a local populace remeniscent of characters from Deliverance . Never do field work in Kentucky unless you really have to I Springtime found myself as 100% of the crew of the notorious Captain Platt and involved in a study of the igneous rocks found in the Lake Superior Islands and of the nepheline syenites found on the Marathon Riviera - field work not to be missed if you ever get the chance - one of the most beautiful parts of Lake Superior. July found Dr. Platt and myself encamped upon some awfully stoney ground in the permafrost desert called Bathurst Island. Our work there sponsored by the Federal Polar Continental Shelf Project, was to make a de- tailed study of the Freeman ' s Cove volcanic rocks, these are the second only known occurrence of nephelinite in North America. During the work Dr. Platt did an excellent job as gunbearer, wreaking havoc amongst the oil drums with the 30-06, but failed abyssmally in attracting any polar bears. In fact, the fiercest beast we came across was a long-tailed jaegar. The fall saw me once more in the desert, but this time in the very hot Arizona desert. As a part of the Second International Kimberlite Conference field trips were organized in the U.S„ southwest. Here I collected kimberlites, minettes and pieces of mantle to compliment my studies of Canadian and South African upper mantle material. Much of the field work involved such activities as pushing rubber rafts down the San Juan River Canyon, climbing mountains under the blistering hot sun or coughing ones way around sagebrush and cactus in sandstorms. All very enjoyable and some 70 petrologists were kept on the liquidus by consuming some 5000 cans of beer over ten days. In all this was the most Interesting field work of the year as I saw recent volcanism, the Grand Canyon, Monument Valley, the Rio Grande Rift, and a wide variety of igneous rocks.
