Dr. John Sydney Mothersill , B.Sc. (Physics, Mathematics) B.Sc. (Geological Engineering) Ph.D. Background ; Exploration Geologist for Standard Oil (N.J.) Senior Geologist for Mobil International Oil Co. Exploring for petroleum in Turkey, Nigeria, France and Colombia, 1956-64 Associate Professor, Lakehead University 1966-78 Professor, Lakehead University 1978-present Dean of Science at Lakehead 1975-present The primary areas of research in which I have been involved during the past several years are late-Quaternary paleomagnetic studies and sediment- ologic studies. The paleomagnetic studies consist of determining the late- Quaternary paleo-declination , paleo-inclination, paleo-susceptibility and paleo-magnetic intensity columns for northern Lake Superior for time parallel correlation purposes. This study has been extended into eastern Lake Superior and Lake Huron to provide a time parallel correlation grid for the Great Lakes. In addition, the natural remanent magnetic direction will be used to determine the virtual geomagnetic path for the late-Quaternary. The sedimentological studies were centred around the Batchawana Bay area and emphasize the use of grain size parameters as determined by the method of moments to discriminate environment and sub -environment processes. The Batchawana area, which comprises a number of sedimentological environments, will be used as a model for the post-glacial sediments exposed along the east- ern part of Lake Superior and for the deep-water lakes in general.

Dr. Edward Mercy , B.Sc., Ph.D., D.I.C. Background ; Lecturer in Geology, Imperial College of Science and Technology, London, England Lecturer in Geology, later Senior Lecturer in Geology, University of Edinburgh, Scotland Professor of Geology and Chairman of the Department, Lakehead University 1967-76 Professor of Geology at Lakehead 1976-present Most of the existing textbooks of geochemistry are disappointing to anyone who has a real interest in the subject matter. They are disappointing because, in attempting to be comprehensive, they trivialize the subject. There are serious economic constraints on the size and cost of a publication intended primarily for the university student market. Comprehensiveness flies out the window and the house is occupied by a poor half-starved creature mas- querading as geochemistry. The falsity of his pose is compounded by hie declaration that parts of mineralogy and petrology may be offered as substantial fare for those who hunger after knowledge. The essence of this purveyor of mis-inf ormation is his belief that he knows about that which he writes and that all that he writes is all that is needful to know. That he does it deliberately can hardly be maintained. That he does it at all must be because he knows no better. A serious critic ought to be prepared to redress the iniquities he discovers in others even though in doing so he may impose upon himself a task of some con- siderable magnitude. Naturally, having made the decision to play the role of creator rather than critic, he then seeks to place limitations on the nature and extent of his dissertation so that the result may have a defined purpose. Despite the gross enlargement and mis-use of the term in recent years, geochemistry is properly concerned with the distribution of the chemical elements in Earth and is, in this proper connotation, a fascinating subject of study with important, and sometimes critical, implications for the general scientific understanding of our planet. There are three limitations on the scope of the proposed textbook which provide the essential framework within which the principles of geochemistry may be established. The first is that the overall chemical composition of Earth and the manner of its formation and rapid evolution into a heterogeneous body must be assumed on the basis of the extensive knowledge provided by astronomers, meteoriticists , and geophysicists. The second is that the accessible igneous rocks of Earth ' s crust, knowledge of these being provided by mineralogists and petrologists , are suitable objects of study for the provision of the necessary geochemical data. The third is that the writer and the reader have a sufficiently wide and detailed knowledge of geology and chemistry that the discovery and illumination of principles takes place without laborius, tedious and repititious explanation . Given these parameters and provided that the focus of attention is firmly fixed on the behaviour of the elements, then a textbook can be constructed. Whether it has any principles - the author assumes as a philosophy that principles do exist to be discovered and explained - is for the reader to decide.
