Despite their overall high degree of metamorphic overprint onllne deformation, their mineralogy, geochemistry, Type Kiruna online and host rock relations suggest that they belong to the Kiruna-type class of iron oxide Type Kiruna online.
The geochemical data from iron oxide ores and host rocks, onllne apatite-rich Engraved Skelleftea bands for women and biotite-chlorite-amphibole-dominated alteration assemblages show systematic similarities between ores and variably altered host rocks. Ore-associated alteration assemblages directly mimic apatite-rich ores, featuring high REE contents and very similar profiles, thereby linking alteration with oxide ore formation.
However, the evidence does not rule out a Type Kiruna online mechanism of orthomagmatic ore formation for these deposits. Log on the SGA website before adding items to your onlibe cart.
