The Conglomerado Cualac is a geologic formation in Mexico. First described by Guzmán in 1959, under the name Cuarcita Cualac. Later, Erben (1956) gave it their actual name. It consist of thick beds of a hard, white and sometimes yellowish conglomerate with a cuarcitic matrix. This conglomerate compounds almost exclusively of milky quartz pebbles between .5 and 5 centimeters of diameter. It also presents, in less quantity, pebbles of schist, gneiss, and tuff. Its thickness varies between 30 and more than 200 meters.[1] It preserves fossils dating back to the Jurassic period.
