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.

这项提案在6个采矿和勘探公司的支持下，将利用新颖的地球物理方法与地质研究相结合，创建高分辨率的横截面，以说明地壳的地质建筑。该方法将在三个具有不同金属end赋的地质环境中开发，包括Abitibi中的黄金，钴中的银和Sudbury中的镍。该提案将开发全波倒置，这是一种地震处理方法，即如果成功将图像垂直和水平地质特征以比当前更高的分辨率形象。当与其他地球物理方法和地质映射结合使用时，该提案将产生地质横截面，达到高达10 km的深度。调查将集中在与大型结构相关的碎屑沉积岩上。沉积学的变化可能反映出地球物理方法成像的基本结构框架。本研究项目将通过说明矿物化区的大规模地质建筑来使矿物勘探行业受益。该方法将说明控制矿物质沉积物的结构和地层地质框架。这将使人们更好地了解控制矿藏的地质过程，并将对采矿和勘探公司，勘探软件 /技术开发人员以及金属基础和构造学研究人员感兴趣。新的地震方法（如果成功）也将适用于其他地质或岩土技术研究，在这些研究中需要分辨近垂直到垂直地质特征。反过来，这将创造就业机会，并维持其运营的地雷及其社区。
