| 1. | These are a group of sandstones defined as feldspathic greywacke.
|
| 2. | The feldspathic formulations are, however, more resilient and suffer less pyroplastic deformation.
|
| 3. | It grows on fine-grained sheared quartz and feldspar rock containing feldspathic quartzite.
|
| 4. | Shales are occasionally thus altered by basalt dikes, and feldspathic sandstones may be completely vitrified.
|
| 5. | High albedo, feldspathic material is the dominant component of the finest particles of lunar soil.
|
| 6. | The Herreria Formation from the Lower Cambrian consists of shale and feldspathic sandstone alternating, with some conglomerate.
|
| 7. | The Rietvlei Formation consists of alternating horizons of light grey quartzose and feldspathic sandstone, siltstone and shale.
|
| 8. | The La Vida Member is a micaceous, platy siltstone with subordinate amounts of thin-bedded feldspathic sandstone.
|
| 9. | It consists of thick-bedded, micaceous, feldspathic quartzite that is light grey, pink, to purplish.
|
| 10. | The formation consists of two members : clastic, mostly feldspathic various grained sandstones, and volcano erupted-alkali lavas.
