Aburrá's Valley Geology.

This article is based on the information contained in the bachelor's degree project of the geologist Andrés Acevedo Gómez. The full reference of the work is the following: A. Acevedo, D. A.

Area of Study

The area of study comprehends Aburra's Valley and its surroundings, its limited at north and at the east by the head of the municipality of Barbosa and the flat coordinates y=1 205 000 and x=863 000 respectively, at the south by the flat coordinate y=1 645 000 and the head of the municipality of Caldas, and at west by the Western limit of the Quebradagrande formation. The coordinate system is Bogota 1975 / Colombia Bogota zone EPSG:21892.

To make this project, the cartography used in Rendón, D. A., 2003. Tectonic and sedimentary evolution of the Upper Aburrá Valley, northern Colombian Andes. Tesis de Maestría, Universidad de Shimane. Japón, 203 pp. Was used.

Cross Sections.

Using the cartographical, geological and geophysical information, 21 cross sections, east west, with a separation of 2 Km and a depth of 30 Km were created. 11 of those sections can be found in [[article:Secciones Transversales]]. In the next interactive visualization in 3 dimensions, you can see these cross sections and the geological map:
