RT Journal Article T1 Procesos de dolomitizacíón acaecidos en las sedimentitas carbonáticas del Ordovícico Inferior de la Precordillera, San Juan, República Argentina T1 Dolomitization processes occurred in Lower Ordovician carbonatos of Precordillera, San Juan, República Argentina A1 Matheo, S. D. A1 Spalletti, L. A1 Muruaga, C. M. AB Dolomitization processes are recognized in the Lower Ordovician San Juan Formation, Central Argentine Precordillera. The sedimentary sequence is composed by limestones with different textures, predominantly wackestone and biodastic packstone in massive and well laminated deposits, with typical tabular stratofabric. The main early diagenetic features are represented by incomplete fibrous calcite cement and eogenetic dolomite. Late calcite cement, polimodal dolomite and stylolites are the main burial diagenetic products. The late stages of diagenesis are signed by a third type of dolomite PB Sociedad Geológica de España YR 1996 FD 1996 LK http://hdl.handle.net/10272/12389 UL http://hdl.handle.net/10272/12389 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 31 may 2026
