| description | This study aims to make new contributions to the knowledge and interpretation of paleoenvironment of Guaduas Formation´s coals, Superior Maestrichtian to Paleocene age. Petrographic analysis of 64 samples collected them by the channel method in three sections of the Checua-Lenguazaque syncline (Sutatausa, Guachetá and Samacá), establishing that the coals are composed mainly of macerals of the vitrinite group with percentages between (51.4% - 87%), followed by the inertinite group (5.4% - 43.8%), liptinite (0.2% - 14%), and mineral matter (0.4% - 18%). The average vitrinite reflectance ranged from 0.69 to 1.6; showing bituminous coals C to bituminous coals A. The maceral reading allowed the determination of the distribution of organic components of coal to implement the methodology proposed by Diessel (1992) and the used it by Singh & Singh (2000), for the definition of palaeoenvironments; concluding that the coals of Guachetá and Samacá blocks were deposited in environments of protected areas for barriers and bogs mainly, while the coals of the Sutatausa block extended into wet-forest swamps. Table water although variable, covered the peat bog which favored the preservation of organic material against oxidation. |

El presente estudio, tuvo como objetivo realizar nuevos aportes al conocimiento e interpretación del paleoambiente de los carbones de la Formación Guaduas, de edad Maestrichtiano Superior a Paleoceno. Se realizó el análisis petrográfico de 64 muestras colectadas con el método de canal en tres secciones del sinclinal de Checua-Lenguazaque (Sutatausa, Guachetá y Samacá), estableciéndose que los carbones están compuestos principalmente por macerales del grupo de la vitrinita con porcentajes entre (51.4% - 87%), seguidos por los de la inertinita (5.4% - 43.8%), liptinita (0.2% - 14%), y materia mineral (0.4% - 18%). La reflectancia media de la vitrinita varió de 0,69 a 1,6, con rango de carbones bituminosos C a bituminosos A. La lectura maceral permitió determinar la distribución de los componentes orgánicos del carbón a fin de aplicar la metodología propuesta por Diessel (1992) y la usada por Singh &amp, Singh (2000) para la definición de paleoambientes, concluyéndose que los carbones de los bloques Guachetá y Samacá fueron depositados en ambientes de zonas protegidas por barreras y ciénagas principalmente, mientras que los carbones del bloque Sutatausa se extendieron hasta pantanos de bosque húmedo. La tabla de agua aunque variable cubría la turbera, lo cual favoreció la conservación de la materia orgánica frente a la oxidación.
