Lithological and textural controls of Mississippi Valley type mineralization of mantles in Shalipayco, Junín, Peru

Descripción del Articulo

The problem to be solved was which types of lithological, textural and structural controls were favorable to the mineralization of the Shalipayco deposit. Geochemical exploration, sedimentological studies, geological mapping, stratigraphic columns and diamond drilling were carried out, furthermore,...

It was found mineralized mantos of the Shalipayco project are located lithostratigraphically within the rocks of the Pucara Group, specifically in the Chambara Formation with lithological control of the mineralized mantos, they are coarse to medium grained dolomites (wackestone and packstone) present vuggy type porosity, and the most important textures favorable to the mineralization of the mantos are the evaporitic tectonic breccias, evaporitic breccias, crackel breccia, evaporitic pseudobreccias, and porous dolomites where the dissolution cavities are filled by crystallized dolomite and/or Zn and Pb sulfides.
