| 11. | Granites and detrital zircons have notably similar and episodic appearances in the rock record.
|
| 12. | Many of the Earth's detrital sediments create and cycle nutrients and biominerals.
|
| 13. | Detrital sedimentary graded beds are formed from erosional, depositional, and weathering forces.
|
| 14. | Graded beds formed from detrital materials are generally composed of sand, and clay.
|
| 15. | It also is found in metamorphic amphibolites and as a detrital component of some sediments.
|
| 16. | Deposits of detrital colluvium can reveal the soil composition and signify processes of chemical weathering.
|
| 17. | After lithification, shale, siltstone, and sandstone are formed from the detrital deposits.
|
| 18. | As plants decay, " detrital " nitrogen and phosphorus is returned to the soil.
|
| 19. | These detrital zircons are taken from the sands of major modern rivers and their drainage basins.
|
| 20. | Detrital production occurs continuously, limited only by inputs and advection out of the Delta system.
