A domain-based digital summary of the evolution of the Palaeoproterozoic of North America and Greenland and associated unconformity-related uranium mineralization
Abstract Studies of the evolution of the Earth require a better understanding of regional geological geology, particularly for earth scientists who do not have broad, domain-specific knowledge. The Palaeoproterozoic geology of North America and Greenland has been summarized at domain level using the database system developed for the IGCP 509 project “Palaeoproterozoic Supercontinents and Global Evolution”, with additional geochronological information from the DateView database. A series of diagrams illustrate and contrast the geochronology and isotopic evolution of the Trans-Hudson Orogen and its bounding older crustal domains. These are accompanied by several time-space correlation charts and time-slice tectonic reconstructions showing the lithostratigraphy of the region. The origin and setting of uranium mineralization in Canada is discussed in order to illustrate the knowledge potential captured within these databases.
