This study is focused on the hydro geochemical characteristics of Mishca river located at Victor Fajardo province, Ayacucho department.The geochemical dispersion in water shows metallic values of silver, lead and zinc belonging to the Pucará metallotect mine-ralization cycle. Observed metals in water association are explained as part of the natural dispersion in water.

The high parts of Mishca river basin located in the province Victor Fajardo, district Canarias of Ayacucho department, morpho-logically is located at interandean valleys sector; geologically in the western side of Eastern Cordillera, whose main structural dominium belongs to units from Paleozoic and Mesozoic Ages, with the litostratigraphic units: Mitu Group (Upper Permian- Triassic), Pucara Group (Upper Triassic-LowerJurassic), Chunumayo Formation (Middle Jurassic); magmaticactivity is represented locally by Querobamba Granite related to Upper Paleozoic magmatic cycle.

La cuenca alta del rio Mishca ubicada en la provincia Víctor Fajardo, distrito Canarias del departamento de Ayacucho, morfológicamente se ubica en el sector de los valles interandinos; geológicamente se ubica en el lado occidental de la cordillera Oriental, en el cual el dominio principal es de unidades pertenecientes al Paleozoico y Mesozoico los cuales corresponden a las siguientes unidades litoestratigráficas: Grupo Mitu (Pérmico superior-Triasico), Grupo Pucara (Triasico superior-Jurasico inferior), Formación Chunumayo (Jurasico medio); en lo referente al magmatismo es el intrusivo de Querobamba que pertenece al ciclo magmático del Paleozoico superior. Toda esta sucesión estratigráfica es cubierta de manera discordante por depósitos recientes del Cuaternario.
