The phycosiphon record in the Ladrilleros-Juanchaco section (Miocene, colombian pacific): Palaeoecological implications

Universitat de Valencia
 Miocene rocks of the Ladrilleros-Juanchaco section, located on the NW margin of South America, contain a high diverse and abundant trace fossil assemblage. The relative abundance of Phycosiphon, together with its morphological variations, provides new insights into the environmental conditions. Detailed outcrop stratigraphic, ichnological, and geochemical analyses carried out in the section focused on the trace fossil assemblages (distribution, relative abundance), ichnofabric index, and, especially, in the general ichnological features of Phycosiphon . In addition, the detailed photographic documentation and the use of the digital image treatment technique facilitate the precise study of particular ichnological properties. Based on the stratigraphic analysis of the section, together with the abundance, size and distribution of the specimens of Phycosiphon , as well as the analysis of total organic carbon, the record of Phycosiphon is proved as related to the food content in the sediment, and then as a proxy in the study of ancient environments.

El conocimiento estratigrafico del relleno sedimentario del segmento onshore de la cuenca de ante-arco Tumaco es poco conocido y los trabajos existentes se fundamentan en el estudio de lineas sismicas y pozos para la exploracion de hidrocarburos, haciendo poco enfasis en las unidades mas superficiales. Se presenta el estudio detallado de las rocas del Mioceno superior – Plioceno expuestas en el sector sur de la cuenca Tumaco. Los nuevos datos estratigraficos del pozo ANH-Tumaco 1-ST-S representan la seccion mas completa y mejor preservada de este intervalo de tiempo. Se integro esta informacion con nuevos datos de ~200 m de secciones estratigraficas levantadas en afloramientos de los acantilados de la bahia de Tumaco y del rio Patia. A partir de la descripcion detallada de estas localidades, y siguiendo los parametros de los codigos estratigraficos, se propone emplear el termino Formacion Cascajal para referirse a las rocas volcanoclasticas de edad Messiniense parte superior a Zancliense. Esta sucesion con un espesor observado de hasta 405 m esta conformada principalmente por gruesos estratos lenticulares y ondulados de arenitas y conglomerados, con alto contenido de detritos volcanicos, en menor proporcion, interestratificaciones de lodolitas y arenitas lodosas, localmente con icnofosiles y fosiles de bivalvos, gasteropodos, foraminiferos, equinodermos, crustaceos y restos de plantas bien conservadas, depositados en un ambiente de sedimentacion deltaico influenciado por vulcanismo.Palabras clave: Pacifico colombiano, ante – arco, cuenca Tumaco, codigo estratigrafico, vulcanismoForma de citar: Echeverri, S., Pardo-Trujillo, A., Borrero, C., Cardona, A., Rosero, S., Celis, S.A., y Lopez, S.A. 2016.
