Chango Real Formation is part of Lower Paleozoic magmatism in Sierras Pampeanas Range, Northwestern Argentina. It is a biotitic, granitic ortogneiss, peraluminous, calcalkaline from Cambrian(?), different from others Ordovician batholiths. The origin of the magma was in a convergent active margin of plate, generated in the middle crust. It evolved by fractional crystallization (the last stage ended at 4 kb and 680&#194;&#186; C) and was deformed during Famatinian Cycle (Ordovician-Silurian).  La Formaci&#243;n Chango Real (sierras de Culampaj&#225; y Papachacra) es parte del magmatismo paleozoico de las Sierras Pampeanas noroccidentales (NW de la Argentina). Es un ortogneis gran&#237;tico, biot&#237;tico, que en su grado m&#225;ximo de deformaci&#243;n alcanza caracter&#237;sticas de gneis milon&#237;tico. La composici&#243;n es monzogran&#237;tica a granodior&#237;tica, con t&#233;rminos tonal&#237;ticos. Las caracter&#237;sticas geoqu&#237;micas son peraluminosidad y calcoalcalinidad, diferentes de otros batolitos ordov&#237;cicos (Velasco y Capillitas). El magma se considera generado en la corteza media, en un borde de placa activo convergente, con caracter&#237;sticas normales de madurez del arco magm&#225;tico. Termin&#243; de cristalizar a unos 680&#194;&#186; C y 4 kb. La deformaci&#243;n ocurrida durante el ciclo Famatiniano (Ordov&#237;cico-Sil&#250;rico) le dio caracter&#237;sticas definitivas
