We studied the Hickory Sandstone Member of the Riley Formation, Central Texas, to assess the diagenetic history of a cratonic sandstone, which, in spite of its great age, remains porous and permeable where it has not been buried more than 1 km. Owing to its stratigraphic position between Precambrian basement and overlying, low-permeability carbonate rocks, the Hickory was a potential pathway for fluids expelled from the Ouachita orogen.
