Abstract
In this paper we resume the geological and essential mineralogical characteristics of the phosphated mineralization found in the Silurian of W sector in the Pontevedra province, in "Punta Corveiro", south of La Lanzada beach. The mineralization appears in centimetric fractures in a level of black quartzites, shales and lidites, and consists of variscile, turquoise and occasionally crandallite and quartz. The mineralogical and chemical characteristics of these minerals have been determined by polarized microscope, X-ray diffraction (XRD) and electron microprobe (EDAX)
