Geologic modelling and Hydrogeology
“We put the geology back into hydrogeology.’
We provide high quality reconstructions of geological systems as the foundation of hydrogeology work. Every study site is data limited, and we overcome this by applying our deep understanding of geologic processes. Our president Timothy Johnsen has completed numerous hydrostratigraphic/ geologic modelling projects to support hydrogeologists modelling groundwater systems, contaminant transport, groundwater-surface water interactions, and thermal effects.
Surficial geology and terrain mapping
“Seeing into the Earth by examining its surface.’
Geomorphologists identify landforms that contain characteristic geology and materials types. In effect we can see through the Earth surface to know what materials lie just beneath the surface.
Geomorphology lies at the intersection of many diverse disciplines and consequently there are many ways in which geomorphologists can add value.
Many geoscience problems involve sediments that are at the surface of the Earth, and often a key activity is mapping the distribution of surface/ surficial materials. There are numerous applications ranging from slope stability, aggregate exploration, mineral exploration, fluvial geomorphology, groundwater-surface water interactions, geotechnical engineering, etc. We provide high quality mapping of surficial deposits tuned to the particular problems of our clients.
“Exploration is Quaternary geology in Canada’
High latitude countries like Canada have an extensive cover of glacial sediments from repeated glaciations that make exploration challenging. Consequently, sand and gravel (aggregate), diamond, and mineral exploration greatly involve expertise in Quaternary/ glacial geology.
Sand and gravel exploration
In most areas where sand and gravel are needed, the easy targets have already been discovered. Newer discoveries require the expertise of geologists especially trained to make the next discoveries. A combination of skills are needed including geomorphology, geophysics, and geologic modelling. Significant deposits of sand and gravel can be hidden just beneath the surface, but to the untrained lie unnoticed. Other deposits may be related to historic changes in sea level or glacial lake levels, but are overlooked because of a lack of expertise.
Diamond and mineral exploration
Diamond and mineral deposits are often buried and hidden by glacial sediments. The easy diamond and mineral targets have already been discovered. Often, glacial histories are complex involving multiple episodes and with multiple directions of ice flow, creating complex indicator mineral dispersal patterns that make tracing to deposits difficult. We provide a solid understanding of the glacial history of an area that results in a better rationalized sampling strategy, reducing exploration costs and greatly improving the odds of finding targets that would be otherwise missed.
