Abstract: The Pucará Group is an important metallotect that hosts base metal deposits (Zn-Pb-Ag) throughout the Peruvian Andes; Mississippi Valley Type (MVT) mineral deposits such as the San Vicente Mine, the Grande Mine, the Chica Mine, the Cañón Florida Project, the Cristal, Florcita, San José prospects and others in northern Peru were located between the Eastern Cordillera and the Subandean Belt, all hosted in the carbonate rocks of the Pucará Group. Review of more than 100,000 meters diamond drill cores, observation of geological maps and cross sections, field observations, elaboration of the stratigraphic columns and geological interpretation indicate that Late Triassic/Early Jurassic Pucará Group rocks hosts mineralized bodies of (Zn-Pb-Ag) from the Cañón Florida Project and they were deposited at certain favorable stratigraphic levels between the Intact Bivalve Marker (IBM) and Coquina Marker (COQ) biostratigraphic horizons in dolomitized carbonate rocks of the Chambará 2 Member of the Chambará Formation of the Pucará Group, in this way the biostratigraphic controls in combination with other methods and exploration techniques are guides for mineral exploration of Mississippi Valley Type (MVT) deposits.
