Cretaceous sandstones, marls, limestone and silicified limestone. Limestone and sand are sporadically quarried here for use by a bottle glass factory in Cochabamba city. For mineral collectors, the locality is better known for its bicolored fluorescent rock (the silicified limestone), originally discovered by biologist and lapidary artist Belisario Rioja in the mid-1990s.
