Kurravaara conglomerate (Swedish: Kurravaarakonglomeratet) is a rock unit of polymict conglomerate found in northernmost Sweden.[1] It rest confomably on top of greenstones that were originally basaltic lavas and tuff.[1] [2] In one locations both rock units interdigitate.[1] The conglomerate has boulders of porphyritic trachyandesite, iron-apatite oxide and those that are a blend of both rock types. Greenstones are also found as boulders.[1] In some locations the unit is poor in boulders and is made mostly of metatuff.[1] It is overlain by the Hopukka Formation, but no clear contact exists as rock units grade into each other.[2]
