Abstract

•Rapitan iron formation accumulated in sediment-starved sub-basins.•Sediment starvation owing to rotational block faulting at basin margin.•Iron formation thickness linked to timing and amount of sub-basin subsidence.•Rapitan Group accumulated ∼711Ma, later than presumed correlatives.•Inception of glaciation in northwestern Laurentia was diachronous.
