Abstract
En la biblioteca del Ministerio de Defensa se conserva un ejemplar de un mapa manuscrito titulado “Croquis geológico de Montes
de Sierra Bullones a escala 1:20.000”, firmado por los ingenieros de
montes Máximo Laguna y Luis Satorras, en 1861 y que había permanecido hasta ahora inédito para la historiografía geológica. Los
autores fueron dos ingenieros de montes españoles que se habían
desplazado a Ceuta en Julio de 1860 para reconocer el territorio recién anexionado a España tras la Guerra de África (1859-1860). Los
resultados fueron presentados en una memoria y también se levantaron un mapa geológico y uno de rodales. Años después, en 1877,
la memoria fue publicada, sin incluir el mapa geológico. En el mapa
se diferencian cuatro unidades litológicas distintas y en ella se traza,
con notable acierto, los principales rasgos geológicos del territorio.
Este trabajo pretende dar a conocer a la comunidad científica esta
cartografía geológica inédita, que se adelanta en 56 años a la de
Dupuy de Lôme y Milans del Bosch de 1917, que hasta ahora se
consideraba la primera cartografía geológica de Ceuta
The library of the Ministry of Defense keeps of a handwritten map entitled “Geological sketch of Montes de Sierra Bullones at scale 1: 20,000”, signed by the forestry engineers Máximo Laguna and Luis Satorras, in 1861. This map had remained unpublished until now, and therefore hidden for geological historiography. The authors were two Spanish forest engineers who had traveled to Ceuta in July 1860 to recognize the territory recently annexed to Spain after the African War (1859-1860). The results were presented in a report and a geological map and a vegetation map were also created. Years later, in 1877, the memory was published, without including the geological map. Four different lithological units are distinguished on the map, and the main geological features of the territory are traced with remarkable success. This work aims to present to the scientific community this unpublished geological map, which is 56 years ahead of that of Dupuy de Lôme and Javier Milans del Bosch in 1917, which until now was considered the first geological map of Ceuta
