Earth’s middle age, ca. 1.8 to 0.8 billion years ago, witnessed the diversification of early eukaryotic and the gradual oxygenation of the environment that set the stage for the origin of animals. This billion-year interval was bracketed by the formation of two supercontinents whose assembly and break-up likely profoundly influenced ocean chemistry and the spatial and temporal distribution of sediment-hosted mineral deposits. Elucidating the patterns and linkages between tectonic, biogeochemical, and eukaryotic evolution during the middle Proterozoic Era is a grand scientific challenge that is made possible by the extensive and well-preserved middle Proterozoic sedimentary record in northern Canada.

地球中年，加利福尼亚。 1.8至8亿年前，见证了早期真核的多样化和为动物起源奠定了阶段的环境的等级。这十亿年间的间隔是由两个超中国形成的，它们的组装和分裂可能深远影响了海洋化学以及沉积物托管矿物质沉积物的空间和临时分布。阐明中古生代中期的构造，生物地球化学和真核进化之间的模式和联系是一项巨大的科学挑战，这是加拿大北部北部的广泛且保存完好的中国水生代沉积记录使得巨大的科学挑战。
