Río Nío
The ore of manganese found in the northern part of the province of Tucumán is presented as Psilomelane, Pyrolusite and Cryptomelane, appearing as deposits in the area of Puerta Quemada and the river Nío, about 42 kilometres from the city of San Miguel de Tucumán.
The Puerta Quemada and river Nío region consists of gentle hills, with gullies and streams with clayey sandy beds. The hills are covered by Andean meadows which contrast with the western slope of the Sierra of the Ramada and El Nogalito Estero.
The exposed terrain in the region is composed of Sandy-Clay material with interbedded cinerites and conglomerates. In a profile of the area, is observed after a chemical cover, the succession of clays, marls, boulders, sand, volcanic ash, loose, reddish or pink, clayey sandstone horizons more clay from 0.40 to 1 meter thick carriers of manganese nodules; There are then sandstones of dolls, hard sandstone and calcareous sandstones, all belonging to the Tertiary-Mesozoic.
Puerta Quemada ore is low-grade and unevenly distributed, occurring as scattered nodular limonite concretions of variable size and enriched with ore of manganese in a significant proportion.
