安大略省东部马尼托巴省、安大略省西部和北达科他州东部上克拉通基底的磷灰石裂变径迹年龄记录了晚元古代后生和侵蚀两个时期。后者包括威利斯顿盆地东侧下方和邻近的基底，先于盆地下沉，在时间上大致与元古界超大陆的解体重合。我们推测，这些事件与基因有关。
Apatite fission-track ages of basement from the Superior craton in eastern Manitoba, western Ontario and eastern North Dakota record two periods of Late Proterozoic epeirogeny and erosion. The latter period, which involves basement beneath and adjacent to the eastern flank of the Williston Basin, precedes basin subsidence and roughly coincides in time with breakup of the Proterozoic supercontinent. We speculate that these events are genetically related.
