Note that the modern state boundary and geologic locations are used, and features related to the post-early Eocene east–west extension are not included. For simplicity, only major rock units in the source regions are shown. The black box indicates the studied region in western North Dakota. ...
60 km. In terms of topography, e.g., in the remote sensing images, this fault is as a very clear boundary between Archean basement and Jurassic-Cretaceous strata to the south and the QPU to the north (Fig. 1, Fig. 2a). The QPU region exposes mainly the Middle-Late Proterozoic ...
The positive Eu anomalies (1.3–4.2; average = 2.2) that occur throughout BIF samples suggest a continuous flux of submarine, high-temperature hydrothermal fluids to the ocean at the Archean–Proterozoic boundary. Based on elemental mass balance, the proportion of submarine, high-temperature ...
