A rare mineral containing magnesium, titanium, and iron that sometimes forms in metamorphic and igneous rocks.
Derived from the genus Geikia combined with the mineral suffix '-ite'. It follows the pattern of naming minerals after plant genera or people—in this case, possibly honoring both Geike and the plant genus Geikia.
Geikielite is so rare that most geologists never see a specimen—it represents one of thousands of minerals that exist but are so uncommon that they're primarily known through scientific catalogs and mineral collections.
