| 1. | It consists almost entirely of granodiorite with large crystals of orthoclase.
|
| 2. | The main minerals are quartz, perthitic orthoclase, and plagioclase.
|
| 3. | The presence of orthoclase indicates a petrogenetic difference with nepheline gabbros.
|
| 4. | Most intrusions of this age are heavily sheared orthoclase porphyroclastic granites.
|
| 5. | It contains also orthoclase, nepheline, biotite, aegirine, acmite.
|
| 6. | Microxenocrysts of orthoclase likely exist in andesite at Ring Mountain.
|
| 7. | Orthoclase crystals are found occasionally and they likely represent xenocrysts.
|
| 8. | Enormous crystals of orthoclase were common, some over five feet in diameter.
|
| 9. | The largest documented single crystal of orthoclase was found in Ural mountains, Russia.
|
| 10. | Typically the host grain is orthoclase or microcline, and the lamellae are albite.
