Plaza Sagrado Corazón 1 , Villafranca Del Panades, Spain...Quartz is found in Spain in every sort
of deposit characteristic of this important
and widely-distributed...species. In
the older rocks, it is present in lodes,
and comprises the gangue in the great
metalliferous mines...arcfound, as might be expected, in granite,
gneiss, and the older sediments and
metasediments. Among the more...notable
quariz occurrences in Spain are the great
lode in the granite of the Veta del Cura,
