Dr. J. M. Bell, FRGS: A Canadian Auxiliary Geographer in New Zealand

Using Hodder’s notion of “biography as method,” this paper examines the geographical endeavours of James Mackintosh Bell, Director of the New Zealand Geological Survey from 1905 to 1911, in New Zealand and Canada. Canadian born, Harvard trained, Bell has a significant place in the history of geology in New Zealand and mining geology in Canada, yet much of his writing was explicitly geographical in orientation. This essay analyses this body of work and its significance and limitations in adding to and disseminating knowledge of the geography of NZ, particularly. Bell credentialed himself geographically as a Fellow of the Royal Geographical Society (FRGS). The FRGS were important builders of geographical knowledge in NZ from the 1850s up to the establishment of university geography in the 1930s when formal geographical research commenced. Geologists were a numerically significant group amongst the NZ FRGS, distinctive in that they held university qualifications, and Bell was particularly wide ranging in his geographical interests.

Urban Geology of Canadian Cities (P. F. Karrow and O. L. White, Editors)

To those well read in urban geology, Canada is the ‘land of Legget.’ Robert F. Legget, to whom Urban Geology of Canadian Cities is dedicated, created the domain of urban geology by writing the classic text Cities and Geology, which McGraw-Hill published in 1973. According to articles in the Special Paper reviewed here, interest regarding urban geology in Canada declined significantly after 1973 and did not re-emerge until 20 years later. The editors of this volume, Paul F. Karrow and Owen L. White of the University of Waterloo, have been responsible for keeping that flame alive in Canada. This handsome volume of 500 pages begins with two introductory papers, the first by John Scott of the Geological Survey of Canada (GSC) and the second by the editors. Scott describes the difficulties of gaining commitments at the municipal level to compile geotechnical information, the need for development of user-friendly information systems, and the necessity of demonstrating the importance of geological knowledge to the resolution of urban geotechnical and geoenvironmental issues. Scott is candid about the fitful commitment of his own institution to urban geology, but he also describes the renaissance that the field underwent during the 1990s, when the GSC became re-involved in the matter, particularly in Vancouver and the National Capital Region of Ottawa and Hull, its sister city in Quebec. In their introduction, the editors lay the groundwork by identifying the four basic issues that they wished the invited authors to address: 1) general and historical information about the city, 2) its geological setting, 3) its geotechnical features, and 4) a review of geotechnical databases developed since the early 1970s. They then summarize the information provided …

RADARSAT and Radar Geology in Canada

RESUMEEn attendant la disponibilite des donnees RADARSAT, le Centre canadien de teledetection a acquis des images recueillies par radar aeroporte a antenne synthetique (RAS) sur plusieurs sites au Canada. Cet article passe en revue un certain nombre d'etudes canadiennes recentes sur l'utilite des donnees RAS en geologie. Ces etudes portent surtout sur le type d'information geologique que l'on peut tirer des donnees RAS ou de la combinaison de ces donnees avec d'autres series de donnees geologiques et geophysiques sur lesquelles s'appuient la cartographie et l'exploration geologique ainsi que les etudes sur les risques de nature geologique.

Clifford Symington Lord, 1908-1981

Dr. C.S. Lord, formerly Chief Geologist of the Geological Survey of Canada and Chairman of the Board of Governors of The Arctic Institute of North America, died in Ottawa on 4 October 1981. With his passing Canadian earth science lost one of its most able and knowledgeable geologists, especially of the Canadian Shield in the Northwest Territories, as well as one of its most modest and dedicated servants. ... Clifford Lord's broad regional and varied logistical experience, coupled with his demonstrated organizing ability, made him a natural choice in 1954 for Chief Geologist of the Geological Survey - a post he held with distinction for nearly 20 years. This was a period of great expansion and diversification of the Geological Survey program. Although he understood the value of geophysical and geochemical surveys, many of which were begun and carried out during his term as Chief Geologist, he always maintained that geological surveys were the core activity of the Survey and provided the ground truth against which other types of geophysical and geochemical surveys should be judged. While Chief Geologist he introduced a project management system, which though perhaps somewhat cumbersome, was years ahead of its time in the Federal Government. The essence of his system, in a more streamlined form, is used by the Survey today. During most field seasons he visited numerous field parties to learn, first-hand, the geology of various regions of Canada, to become familiar with new techniques, and to observe how the scientists operated in the field. ... Between 1963 and 1971 C.S. Lord carried out many assignments on behalf of the United Nations, Canada's External Aid office and its successor, the Canadian International Development Agency (CIDA). ... As an authority on the geology of the Canadian Shield north of latitude 60° he was elected a Fellow of The Arctic Institute of North America. Furthermore, owing to his Arctic experience, his influential position as Chief Geologist of the Geological Survey, and his administrative talents, he served as a most useful member of the Board of Governors of the Institute, being Chairman in 1960. ... He contributed much to our understanding of the geology of Canada, especially the Precambrian of the Arctic, and provided practical advice for mineral development. Because of his modesty, few except those who followed in his footsteps, appreciated the magnitude and quality of his achievements.

This paper presents the results of an investigation on a Deep Seated Gravitational Slope Deformation (DSGSD), previously only hypothesized by some authors, affecting Bisaccia, a small town located in Campania region, Italy. The study was conducted through the integration of conventional methods (geological-geomorphological field survey, air-photo interpretation) and an Advanced-Differential Interferometry Synthetic Aperture Radar (A-DInSAR) technique. The DSGSD involves a brittle lithotype (conglomerates of the Ariano Irpino Supersynthem) resting over a Structurally Complex Formation (Varycoloured Clays of Calaggio Formation). At Bisaccia, probably as a consequence of post-cyclic recompression phenomena triggered by reiterated seismic actions, the rigid plate made up of conglomeratic sediments resulted to be split in five portions, showing different rates of displacements, whose deformations are in the order of some centimeter/year, thus inducing severe damage to the urban settlement.A-DInSAR techniques confirmed to be a reliable tool in monitoring slow-moving landslides. In this case 96 ENVIronmental SATellite-Advanced Synthetic Aperture Radar (ENVISAT-ASAR) images, in ascending and descending orbits, have been processed using SUBSOFT software, developed by the Remote Sensing Laboratory (RSLab) group from the Universitat Politècnica de Catalunya (UPC). The DInSAR results, coupled with field survey, supported the analysis of the instability mechanism and confirmed the historical record of the movements already available for the town.

Tectonics and structural geology in Canada

The present investigation of the Tertiary succession offshore South Gabon is based on seismic surveys of 1985–1989 vintage and wells covering the southern part of Gabonese waters.In general, the Tertiary basin off South Gabon evolved during two structural stages. During the Paleocene and Early-Middle Eocene, a trough-like basin subsided slowly towards the west. During this period there was a cyclic development of the succession which consists of up to four sequences mostly bounded by Type 2 sequence boundaries. The sequential changes were induced by eustatic sea-level changes. This pattern changed during the Neogene when the evolution was characterized by continental crustal flexuring in Early-Middle Miocene times. This resulted in strong subsidence of the western part of the basin and uplift of the eastern part. Consequently, the eastern part was exposed to strong erosion and a thick Middle Miocene succession was deposited west of the shelf (approximately the present-day shelf), especially on the slope. The clinoformal and lens-shaped Middle-Late Miocene succession which consists of four sequences bounded by Type 1 sequence boundaries has been controlled by eustatic changes in sea level.In addition to the overall subsidence pattern, salt tectonics has modified the external and internal architecture of the sequences on a local scale. Canyon formation in connection with slumping results in the establishment of well developed fan systems on the lower part of the slope and on the basin floor area.

Peter Kalm's geological observations in New France, 1749

In 1749 Peter Kalm, a Finnish professor and naturalist, journeyed up the Hudson River, across Lake Champlain, to Montreal and thence down the St. Lawrence River. His notebooks of this journey contain many geological observations, the accuracy of which is remarkable, and merit him a place in the early history of the geology of Canada.

Notes on the Pre-Cambrian of the Canadian Shield with Reference to Pre-Cambrian Nomenclature

The pre-Cambrian geology in Canada is in an unsatisfactory condition, due not so much, to disagreement regarding fundamental facts and history, as to words and the control they exercise upon ideas.
