| 31. | Monazite, because of its magnetic properties, can be separated by repeated electromagnetic separation.
|
| 32. | Monazite is radioactive due to the presence of thorium and, less commonly, uranium.
|
| 33. | Thorium content of monazite is variable and sometimes can be up to 20 30 %.
|
| 34. | Monazite from certain carbonatites or from Bolivian tin ore veins is essentially thorium-free.
|
| 35. | Subsequent investigations found the source of the radiation was natural, originating from monazite deposits.
|
| 36. | The advantage of monazite geochronology is the ability to relate monazite compositions with geological processes.
|
| 37. | The advantage of monazite geochronology is the ability to relate monazite compositions with geological processes.
|
| 38. | Monazite and zircon are two minerals that commonly employed in geochronology to study geological history.
|
| 39. | These distinctive features can be easily identified with textual and compositional analysis in monazite geochronology.
|
| 40. | The lightest lanthanides are generally better represented in monazite while the heaviest lanthanides are in xenotime.
