| description | A diagenetic and petrographic analysis of 148 thin sections from the Cenozoic units of the ColombianCaribbean was carried out in order to assess the quality of hydrocarbons reservoirs and their possible tectonic provenance. These samples came from 13 slim holes drilled by the ANH in the Fold Belt of San Jacinto. The lithostratigraphic units from base to top are Arroyo Seco, Toluviejo-Chengue, El Floral, Ciénaga de Oro and Sincelejo Formations. Furthermore, a counting of 400 points by thin section was made to determine the composition of the fragments and the different diagenetic products. For each one of the units a diagenetic paragenesis was determined. The processes were subdividing in accordance with the environment in which they originate and the relative time of apparition. In general, in the marine diagenesis occurred a rapid precipitation of carbonates isolately fibrous isopachous and bladed cements were present. In the early metheoric diagenesis the main events are corrosion of silicates and in the late metheoric stage was the dissolution of methasomatisms. In the burial diagenesis the most important processes were: methasomatism of silicate by carbonates, different types of neomorphism and overgrow, well as structures of pressure-dissolution. From the study is determined that the Toluviejo-Chengue and Ciénaga de Oro Formations have the best properties as hydrocarbons reservoirs. Moreover, the composition of the fragments indicates a tectonic provenance from recycled orogen and interior craton. |

Se efectuó un análisis petrográfico y diagenético de 148 secciones delgadas provenientes de las unidades Cenozóicas del Caribe colombiano, con el fin de evaluar la calidad de los potenciales reservorios de hidrocarburos, así como su posible procedencia tectónica. Estas muestras provienen de 13 pozos estrechos (slim holes) perforados por la ANH en el Cinturón Plegado de San Jacinto. De base a techo corresponden a las formaciones Arroyo Seco, Toluviejo, Chengue, El Floral, Ciénaga de Oro y Sincelejo. Para cada sección delgada se realizó un conteo de 400 puntos con el fin de determinar la composición de los fragmentos y los distintos productos diagenéticos. Se determinó además la paragénesis diagenética para cada unidad, dividiendo los procesos según el ambiente en el que se originan y el tiempo relativo de aparición. En general, para la diagénesis marina se presenta rápida precipitación de carbonatos, además de cementos isópacos hojosos y fibrosos aisladamente, para la diagénesis meteórica los principales eventos corresponden a corrosión de silicatos en su etapa temprana y disolución en su fase tardía, en la diagénesis de enterramiento se presentó metasomatismo de silicatos por carbonatos, así mismo neomorfismo, sobrecrecimientos y estructuras de presión-disolución. A partir de este análisis se determinó que las formaciones Toluviejo-Chengue y Ciénaga de Oro presentan las mejores características como reservorios de hidrocarburos. Por otra parte, la composición de los fragmentos indica una posible procedencia tectónica de cratón interior y orógeno reciclado para las unidades de la cuenca.
