Comparación de los Complejos Intrusivos de Jörn y Viterliden en el distrito minero de Skellefte, norte de Suecia
The Skellefte Mining District is located in the northern Sweden, in an early Proterozoic (1.90-1.87 Ga) volcanic arc province in the Baltic Shield. It is composed by a complex submarine volcanosedimentary succession named Skellefte Group overlain by shallow- to deep-marine sedimentary rocks and mafi...
