| 41. | Zonation is a characteristic of monazite.
|
| 42. | These domains are widely accepted to represent episodes in geological history during monazite growth or recrystallisation.
|
| 43. | Monazite grains which show useful relations with microtextures or host minerals are selected for compositional mapping.
|
| 44. | In the case of monazite, the rare earth elements are replaced by Ca and Th.
|
| 45. | It is prepared by solvent extraction from the mixed lanthanides isolated from bastn�site ( or monazite ).
|
| 46. | Historically, mischmetal was prepared from monazite, an anhydrous phosphate of the light lanthanides and thorium.
|
| 47. | Ilmenite is used for extraction of titanium and Monazite for extraction of thorium are found at Bheemunipatnam.
|
| 48. | House bricks are quite soft compared to concrete, monazite and granite, and mortar even softer.
|
| 49. | Monazite is characterised for its high Pb retention ability even at high temperatures for a prolonged period.
|
| 50. | That means one age is generated for a single monazite crystal or for a group of crystals.
