Lineaments of apparent geostructural origin are observable on air photos of the Williston basin. The pattern formed by these lineaments has the appearance of a broad system of interconnecting wrench faults such as occur on the adjacent Canadian shield. On this basis it is hypothesized that a broad system of left-lateral wrench faults may underlie the Williston basin region and possibly the entire continental foreland structural province.
Structures in the Williston basin are readily adaptable to this interpretation. The Nessen anticline appears to consist of a north-south realignment of a N. 40° E.- trending Precambrian high which was segmented by …
