  • Hyginus Rille Formation

    Information on the formation of the lunar crater Hyginus, the Hyginus rille, a series of collapse pits along the rille, and what we identify as a blanket of pyroclasts surrounding the crater. The geometry of the rille graben is consistent with its initiation by the intrusion of a dike that did not breach the surface, and that Hyginus crater may be a caldera formed by surface subsidence into a partly evacuated sill that grew from the upper part of the dike.
