Carbonate hosted hydrothermal ore deposits commonly develop narrow mineral alteration (i.e. visible) haloes, complicating exploration targeting. In contrast, hydrothermal modification of the country rock’s stable isotope composition usually extends far beyond visible alteration. Hence, stable isotope “mapping” is an effective tool to aid exploration for carbonate hosted deposits. However, widespread utilization of stable isotope data has been hampered by its high cost and long turn-around times.
A lack of physical infrastructure and the corresponding fear of harm are a significant barrier to urban cycling, and an impediment to the expansion of Curbside Cycle’s target demographic. Using outreach and education through a collaborative process involving partners Curbside Cycle and Cycle Toronto we will empower local experts, enlist local businesses as powerful community stakeholders, and foster coalitions of community support for improved bicycle infrastructure.
Les feux de forêts naturels sont les perturbations majeures à la base de la dynamique végétale boréale. Les changements climatiques induiront une augmentation des régimes de perturbations. Les régimes de perturbations, la structure et la composition forestière pourraient se diriger vers une variabilité naturelle différente de celle connue précédemment.
This project will carry out original research of a prospective lode gold system located on the western shore of Hudson’s Bay. The location is near the hamlet of Whale Cove. The gold mineralization is intrusive-related, very similar to that of the well known deposits of the Porcupine and Kirkland Lake camps of the southern Abitibi. The research specifically addresses the timing of gold mineralization within the context of related host rock alteration. Currently, there is considerable debate over a Neoarchean or Paleoproterozoic age of mineralization.
There are however, a range of GCMs, future climate scenarios and downscalingtechniques that can be used and each yields different results. Due to this uncertainty, itis regarded as best-practice to use a collection of individual projections to develop“ranges” that characterize future climate conditions. The aim of this internship is toconduct this analysis for the variables of precipitation and temperatures, which will beused directly by the HCA in their assessment of impacts and hydrologic modeling
Reducing GHG emissions and low-carbon living are two prioritized goals of The City of Calgary, Alberta. HEAT (Heat Energy Assessment Technologies), an award winning GeoWeb platform offers interactive geospatial feedback to tackle these issues by visualizing the amount and location of waste heat escaping from homes and communities, as easily as clicking on a house in Google Maps. To ensure wide-spread utility of HEAT metrics, further testing and refinement are required.
The one-year project will investigate the geological, geochemical and geophysical properties of three Rare Earth Element (REE) deposits in Québec. Each of the selected deposit is representative of a class of REE mineral deposits. The project will provide new insights in the origin of the three types of REE mineral deposits. This new understanding of the formation of REE mineral deposits will be transferred to the industrial partners and will be used to improve the odds of discovering REE resources in Québec and Canada.
Saltwater intrusion poses a high level of risk to fresh water resources in coastal communities throughout Canada and the world. Saltwater intrusion is driven by withdrawal of groundwater from aquifers, and by rising sea level. The goal of this work is to demonstrate the usefulness of geophysical methods (electrical resistivity tomography and distributed temperature sensing) for improved monitoring and management of saltwater intrusion at the basin scale. These methods, which are similar to those used in medical tomography, allow for mapping the distribution of saltwater intrusion.
Hydraulic fracturing is a process where fluids are injected in high pressure into wells and fracture the rocks. This process is the driver for shale gas extraction and therefore its efficiency plays a major role for unconventional oil recovery. One of the key questions in such a process is the extent that the pressurized fluids penetrate the reservoir. The goal of this research is to investigate the use of electromagnetic methods for the imaging, identification and control of this process.
L’application de composés alcalinisants tels que la chaux ou la cendre est de plus en plus envisagée dans les érablières du Québec afin d’améliorer le statut acide-base du sol et la nutrition des forêts. Il est possible, cependant, que ces composés provoquent un accroissement de l’activité microbienne du sol, ce qui pourrait augmenter la production de gaz à effet de serre par les sols forestiers.
