At the northern coast of Qeqertarsuaq Island (Disko Island). Tertiary basalt with plagioclase-spinel-graphite bearing xenoliths occurs here. At this locality Steensrup, in 1872, first discovered and reported small lumps and grains of native iron in basalt. Earlier large boulders of native iron, thought to be meteoric in origin, has been found at Niakornak and Uvifaq.
Unique Ti oxides (likely related to Magnéli phases) were found in black, very fine-grained carbonaceous mudstone xenoliths among the reduced andesite breccia. The size of the xenoliths reaches 12 x l0 x 6 cm. They contain up to 2.3 vol% organic fragments (macerals), mainly vitrinite and inertinite.
