AbstractExposed geology represents a random two-dimensional view of a time series of 4-dimensional geological processes. 'Mapping' is the process of combining observations at all scales (micrometre to km) to unravel the sequence of events throughout geological time. In a terrestrial setting, this process involves establishing an inventory of direct and indirect lithological, structural, geochronological and geochemical observations, often mixing systematic and opportunistic data acquisition, and then integrating these data into an internally self-consistent model of terrestrial evolution.
Natural Resources Canada, faced with an immense landmass, a demand for sustainable resource development, and ever increasing costs of operation in the north, is actively investigating a variety of proven and evolving techniques to change the way we 'map'. These techniques include the use of cost effective optical and radar technology for preliminary reconnaissance followed by airborne geophysics, and other airborne remote sensing techniques. The results, combined with any other available data for the particular region under study, would be a first order predictive map. This predictive map would focus the resulting ground follow-up by identifying the areas that have the potential to provide the most information. Subsequent field mapping or 'ground-truthing' and other more traditional activities involving physical specimens such as geochronology, geochemistry and petrology would result in a traditional geoscience 'map' of the area. This map, or more precisely the sum total of the data that this map represents, can then be used as a predictor for similar (typically adjacent) areas, thus expanding the influence of the field mapping.
The RPM goal is to develop the expertise and a toolkit of techniques to allow us to 'map' more effectively and efficiently in a wide variety of situations. Examples from a number of proposed and on-going northern geoscience projects will be discussed.
