| 1. | It has been observed that baddeleyite without twinning is extremely rare.
|
| 2. | Baddeleyite was first found in Sri Lanka in 1892.
|
| 3. | It has been observed in thin section that baddeleyite forms within plagioclase grains.
|
| 4. | Because of this, the coordination of baddeleyite was determined to be sevenfold.
|
| 5. | This explains baddeleyite's tendency to twin along the ( 100 ) planes.
|
| 6. | Its most naturally occurring form, with a monoclinic crystalline structure, is the mineral baddeleyite.
|
| 7. | Zircon and baddeleyite incorporate uranium atoms into their crystalline structure as substitutes for zirconium, but strongly reject lead.
|
| 8. | Baddeleyite forms in igneous rocks low in silica, it can be found in rocks containing potassium feldspar and plagioclase.
|
| 9. | It occurs as interstitial grains with zirconolite, baddeleyite, and apatite associated with late stage intergrowths of quartz and feldspar.
|
| 10. | Baddeleyite's structure is a combination of tetrahedrally coordinated oxide ions parallel to ( 100 ) with triangular coordinated oxide ions.
