Los lapiaces de agujas de Peña Cabarga : Génesis y significado de una forma original

Gaudy cone and pinnacle karsts have been exhumed in many points of Northern Spain by open pit mining activities. Usually considered, without a real basis, as a "tropical climate" inheritance, these forms must be explained as result of iron and lead sulphides alteration in an environment with a conjunction of favourable conditions to karst processes in present-day.
