Stratigraphic and petrographic study of the limestones of the La Tomita sector, in the municipality of Manaure-Cesar, Colombia
Introduction: In the La Tomita sector, municipality of Manaure (Cesar), outcrop a stratigraphic sequence of biomicrite limestones, biopelmicrites, pelmicrites, wackestones and packstones intercalated with shales, corresponding to the Lagunita Formation of the Cogollo Group. Objective: To know the st...
