This work will be accomplished in collaboration with Wallbridge Mining Company, Limited, which owns a large land package of properties in the North Range of the Sudbury complex. Wallbridge will provide a crucial and expensive high-resolution airborne-image of the North Range (~$83,500). The results from this study will provide mutual benefits to both parties involved, and the means for exploring future opportunities between Western and Wallbridge. The main objective is to utilize modern satellite and airborne image processing techniques to identify linear and quasi-linear features associated with the Sudbury impact structure. Some of these features represent fractures and faults associated with the impact event that formed Sudbury. If the spatial density, distribution, geometric pattern and orientation of features tied to the impact event can be reconstructed, then the original diameter of Sudbury may be determined. This in turn will increase our ability to predict were new economic resources deposits associated with Sudbury may be found.

这项工作将与Wallbridge矿业有限公司合作完成，该公司拥有一个 在萨德伯里复杂的北部山脉的大型土地包的财产。沃尔布里奇将提供一个关键的 和昂贵的高分辨率航空照片的北部范围（约83,500美元）。这项研究的结果将 为双方提供互惠互利的机会，并探索未来的机会， 韦斯特街和沃尔布里奇街主要目的是利用现代卫星和机载图像处理 确定与萨德伯里撞击结构有关的线性和准线性特征的技术。一些 这些特征代表了与形成萨德伯里的撞击事件有关的断裂和断层。如果空间 可以重建与撞击事件相关的特征的密度、分布、几何图案和方向， 则可以确定萨德伯里的原始直径。这反过来又会提高我们预测未来的能力。 可能会发现与萨德伯里有关的新的经济资源矿床。
