El origen de las calizas laminadas de los depósitos lacustres someros del sector de La Muela de Zaragoza. Mioceno de la Cuenca del Ebro

Abstract

Marls, laminated limestones, stromatolitic limestones, massive limestones and bioturbated limestones are in Middle Miocene deposits in La Muela región (Ebro Básin). These facies represent the expansion of shallow carbonate lacustrine systems. We mac/e a careful study of laminated limestones using electronic microscopy, which has allowed interpret their biogenic Origin
