RT Journal Article T1 Estructura del sector de Zafra: implicaciones en la subdivisión de unidades Cámbricas de la Zona de Ossa Morena (ZOM) T1 Structure of Zafra Sector: implications on ZOM Cambrian units subdivision A1 Eguiluz, Luis A1 Apraiz, A. A1 Martínez Torres, Luis M. A1 Palacios Medrano, Teodoro AB Detailed geological mapping of the Zafra Sector (central Ossa Morena Zone, ZOM) has shown thé occurrence of a minor synclinal-anticlinal coupled structure compatible with the major structure of the Monesterio Antiform. It has been observed that the Alconera and Zafra units are indeed the same unit, whereas the Los Santos limestone corresponds to the Sierra Gorda and Alconera limestones. These observations may be done extensive to the whole northern limb of the Monesterio Antiform. A revision of classical tectonic units and stratigraphie sequences, appears, therefore, needed in order to a correct analyse of Lower Paleozoic paleogeography within the Ossa Morena Zone PB Sociedad Geológica de España YR 1997 FD 1997 LK http://hdl.handle.net/10272/10551 UL http://hdl.handle.net/10272/10551 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
