Anatase ke mofuta oa liminerale tse nang le methapo e itseng ea titanium. Liminerale ka mefuta ea tlholeho li kopana hangata joalo ka lesela le letšo, leha thepa e hloekileng e se na 'mala kapa e tšoeu. Mefuta e meng e 'meli ea tlhaho ea liminerale tsa TiO2 e tsejoa, e leng brookite ebile e le lesupi.

Anatase e lula e fumanoa e le likristale tse nyane, tse ikarotseng le tse ntlafalitsoeng haholo, 'me joalo ka rutile e tsitsitseng ea thermodynamically, e khanya tsamaisong ea tetragonal. Lejoe la majoe le na le metastable maemong ohle a mocheso le likhatellong, ha rutile e le polymorph ea equilibrium. Leha ho le joalo, anatase hangata ke karolo ea pele ea titanium dioxide ho theha lits'ebetsong tse ngata, ka lebaka la matla a eona a tlase, ka phetoho ea rutile e etsahalang maemong a phahameng a leholimo. Leha boholo ba symmetry bo lekana bakeng sa mekhahlelo ea anatase le rutile, ha ho na kamano lipakeng tsa mahlakore a kopaneng a liminerale tse peli, ntle le sebakeng sa prism sa 45 ° le 90 °. Phiramide e tloaelehileng ea anatase, e tšoanang le lifahleho tsa eona e nang le likhohlo tse phethahetseng, e na le lehlakore le fetang lehlakore la polar la 82 ° 9 ', lehlakore le tšoanang la rutile e le 56 ° 52½'. Ka lebaka la piramite ena e otlolohileng,

Mekhoa e 'meli ea kholo ea likristale tsa anatase e ka khetholloa. Tse tloaelehileng haholo li etsahala e le lipiramite tse habeli tse bobebe tse nang le buluu bo bosootho bo bosootho bo bosootho bo bosootho bo botenya. Makhalase a mofuta ona a mangata Le Bourg-d'Oisans Dauphiné, moo a amanang le rock-crystal, feldspar, le axinite mekoting ea granite le mica-schist. Likristale tse tšoanang, empa tsa boholo ba microscopic, li ajoa ka bongata mafikeng a sedimentary, joalo ka majoe a lehlabathe, letsopa le matlapa, moo a ka arohanngoang le ona ka ho hlatsoa likarolo tse bobebe tsa lefika la phofshoana. Sefofane sa anatase ke sebaka se tsitsitseng ka ho fetisisa sa thermodynamically mme ka hona ke karolo e pepesitsoeng ka ho fetesisa ho anatase ea tlhaho le ea maiketsetso.

Likristale tsa mofuta oa bobeli li na le lifahleho tse ngata tsa pyramidal, 'me hangata li boreleli kapa ka linako tse ling li tloaetse ho fetoha,' mala ke o-sootho ho sootho. Likristale tse joalo li tšoana hantle le sebopeho sa xenotime ka mokhoa o shebahalang, hape, e ne e le ka nako e telele ho neng ho nahanoa hore ke ea mofuta ona, lebitso le khethehileng la bohlale le ntseng le sebelisoa ho bona. Li hlaha li khokahantsoe le mabota a li-artvice ka har'a 'mala oa lithaba tsa Alps, Binnenthal haufi le Brig sebakeng sa canton Valais, Switzerland, e le sebaka se tsebahalang. Li-pseudomorphs tse hlahang ka tlhaho tsa rutile ka mor'a anatase le tsona lia tsebahala.
