Propuesta de caracterización tipológica de yacimientos españoles de metales preciosos

Resumen

Last decade's intensive exploration for precious metals in Spain led to a new understanding of various types of deposits and prospects and to the modification of previous schemes, allowing the systematic (typogical) c1assification of the Spanish precious metals deposits shown in Table 1: 9 large groups and 79 types are defined in the framework of the Iberian Geology. Hypogene deposits in the Hercynian Hesperian Massif, and epithermal gold deposits in the Neogene calc-alcaline Volcanic Province of SE Spain have been very much explored and are therefore emphasized, although their mining production is by far not to compare with the precious metals output from the SW Iberian Pyrite Belt. The exploration significance of the main types and some problems for future research are discussed.
