The inner ring dike is about 20 m in width and lies about 3 km from the center of Richat Structure. Bonnell Earth's Richat Structure, Astronomy Picture of the Day, October Initially interpreted as an asteroid impact structure because of its high degree of circularity, the Richat Structure is now regarded by geologists as a highly symmetrical and deeply eroded geologic dome. Differential erosion of resistant layers of quartzite has created high-relief circular cuestas. Initially interpreted as an asteroid impact structure because of its high degree of circularity, and then as a structure formed by a volcanic eruption that also seems improbable because of the lack of a dome of igneous or volcanic rock, it is now argued to be a highly symmetrical and deeply eroded geologic dome that collapsed.
