•Anorthosites are far more common than previously thought.•Anorthosites have mostly formed in subduction zones throughout the Earth’s history.•Anorthosites have crystallised from tholeiitic or high-Al tholeiitic magmas.•A marked change in the geochemistry of anorthosites occurred in the Proterozoic.•The petrogenesis of anorthosites reflects the secular evolution of the Earth.
