The presence of concretions of manganese in the valleys of the rivers Medina y Calera, in so-called sites "El Timbó" and "El Naranjo", as to its origin, be dealt with deposit "in situ"(singenetics) as a result of possible hydrothermal impregnations ascending of the same or similar origin of limestones of the "Sierra de La Ramada", while making a difference in the rock carrier trying to here there of shale and sandstone.
Is was considered a double origin: "Singenetic", his deposition has been simutáneamente with the cycle of sedimentation of the rock carrier in the form of thin spread in places where it was possible his concentration, and "Epigenetic": when the conditions were favorable to the common phenomenon that governs the formation of concretions, a part of the ore "in situ" acquired the current concrecional structure. A third not disposable origin would be linked to a cycle of from minor sedimentation of a subsequent erosion and resedimentation of the mineral re. As l from manganese source, does not preclude the possibility of the washing of igneous or sedimentary rocks, and possibly linked to intrusions mesosilicious that are common in the mountains of "Medinas".
These concretions should have been formed during the diagenesis in argillaceous sandstone by underground currents that contributed dissolved manganese.
Investigated samples identified the presence of abundant quartz which lies wrapped by a matrix consisting of manganese oxides formed mainly by Pyrolusite and Cryptomelane, featuring quartz features which indicate that it is of clastic origin (sharp grain, size and homogeneous distribution).

El Timbó in the Department of geoenvironmental region is geologically formed by deposits tertiary sandstones of fine grain medium reddish, Brown, etc...; clear brown clay sediments, in green and some micaceous with collations of Gypsum and tobaceo material; within these sediments appear the saline robes of various thicknesses. Groundwater that capture the salts of these sediments, run from its zone of infiltration Northwest towards Southeast, charging to Leach, especially the sandstones, which are the carriers of a salty. This circulation is favored by fractures and porosity of the material. Exploitation and industrialization in commercial scale began in 1944, operating the current plant in the normal way, just from 1954 by initial installation difficulties.

El Timbó brines, Tucumán: the study of the brines, currently in exploitation, allowed to obtain by crystallization of the same, Halite, Mirabilite and Gypsum. These species are present also in the salinas area layers.

Regional Geology

This geological map and associated information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This does not necessarily represent the complete geology at this locality but it gives a background for the region in which it is found.

541 - 1000 Ma

ID: 1376474
Neoproterozoic intrusive and metamorphic terranes

Age: Neoproterozoic (541 - 1000 Ma)

Comments: Mixtures of metamorphic and intrusive or plutonic rocks, tracts known as crystalline, migmatitic terranes, moderately to highly metamorphosed rocks of unknown origin with or without intrusions. This classification is inherently prone to variable interpretation, as other compilers might distinguish some packages by their metamorphic or gneissic protoliths, and the associated age ranges may be more variable.

Lithology: Intrusive and metamorphic terranes
