| Her late husband Walter McCrone studied the map during the 1970s and published micrographs of seemingly synthetic anatase crystals in the ink. |
| Brookite is best known from alpine-cleft-type occurrences, where it is round with anatase, rutile, titanite, quartz, adularia, albite, hematite, calcite, and chlorite. |
| Brookite occurs only as crystals, never in compact masses, and is usually associated with either anatase or rutile. |
| Among the simple oxides, only anatase and hematite have been found to date. |
| In case low concentration of rutile phase is added to anatase phase, photocatalytic properties of titania increase. |
| Small, black, tetragonal anatase crystals associated with rutile were found on microcline by Kile. |
