Description
The Ossa Morena database is the result of several projects carried out jointly by the following bodies:
- The General Directorate of Mines and the Geomining Technological Institute of Spain contracted the national company Adaro to carry out the projects called "Preliminary study for the realization of a database in Ossa Morena" in June 1992 and "Completion and use of the Ossa Morena database" in October 1993.
- The Ministry of Economy and Finance of the Junta de Andalucía contracted in September 1992 to Minas de Almadén y Arrayanes S.A. (MAYASA) the realization of the project called "Ossa Database - Morena - I.- Remote sensing eastern area".
- The Ministry of Industry and Tourism of the Government of Extremadura contracted in July 1993 the research project "Completion of a Geological-Minera database of the Ossa-Morena area" to Minas de Almadén y Arrayanes, S.A. (MAYASA).
During this period of time (1985-1992) several mining prospection projects were carried out in this area on State Reserves, covering a large part of the studied area and in which current research methods were used, with positive results in the metallogenetic knowledge of the Ossa Morena area.
The project comprised three distinct phases:
- A first, which consisted of the collection and analysis of available geological and mining information.
- A second consisted of the application of remote sensing techniques in a large area in the central part of the Ossa Morena area, which allow, on the one hand, the spectral characterization of the different materials that emerge in the work area and, on the other, the realization of the textural study and the structural analysis of the LANDSAT image guidelines.
- And, thirdly, the creation of a multidisciplinary database that allows ordering and managing the large amount of information available and can also be used as a methodological tool for prospecting the area.
The database was incorporated into SIGMA in 1995, when the final database versions were delivered.
