This proposal, supported by 6 mining and exploration companies, will utilize novel geophysical methods combined with geologic investigations to create high resolution cross sections to illustrate the geologic architecture of the earth's crust. This methodology will be developed in three geologic environments with different metal endowment, including gold in the Abitibi, silver in Cobalt and nickel in Sudbury. The proposal will develop Full Wave Form Inversion, a seismic processing method that if successful will image vertical and horizontal geologic features at a higher resolution than is currently possible. When combined with other geophysical methods and geologic mapping this proposal will produce geologic cross sections to depths of up to 10 km. The investigations will focus on clastic sedimentary rocks that are associated with large-scale structures in the areas of interest. Variations in the sedimentology may reflect the underlying structural framework imaged by the geophysical methods. This research project will benefit the mineral exploration industry by illustrating the large-scale geologic architecture of the mineralized districts. The methodology will illustrate the structural and stratigraphic geologic framework that controls the mineral deposits. This will result in a better understanding of the geologic processes that control mineral deposits and will be of interest to mining and exploration companies, exploration software / technology developers, as well as researchers in metallogeny and tectonics. The new seismic methodology, if successful, will also be applicable to other geologic or geotechnical investigations where resolution of near-vertical to vertical geologic features is needed. This in turn will create jobs, and sustain mines and the communities in which they operate.

该提案得到了6家矿业和勘探公司的支持，将利用新的地球物理方法结合地质调查来创建高分辨率的截面，以说明地壳的地质结构。该方法将在三个具有不同金属禀赋的地质环境中开发，包括Abitibi的黄金，Cobalt的白银和Sudbury的镍。
