Feldspar nō kāu poe ma nāʻano o ka potasiuma feldspar, a hiki ke inā paha albite oligoclase. A pōaka inclusions ma māpala i ke ano o ka poe liilii,-pepa paia vitreous mānoanoa. Ka hope paha e ka iki bluish paha colorless. Eia hou, ke paneʻana i ka ninau o ka mea kūpono ai ka māpala, eʻoiaʻiʻo, e nana i ka hoʻi o muscovite a me ka biotite, e like me 'ikamu e like me zircon, magnetite, titanium, apatite a me ka allanite.
