Allanite occurrences in Westland, New Zealand (Note) [PDF]
Abstract Allanite occurs widely as an accessory mineral in granitoid rocks from Westland, New Zealand, and is particularly characteristic of tonalites. It is rare in metamorphic rocks. Microprobe analyses show a fair uniformity in composition; the range of rare earth concentrations (weight percent) is La

Radiogenic Heating as the Thermal Driver of Himalayan Crustal Heating During Prolonged Thickening
Abstract The thermal evolution of the crust during continental collision evolves from cold to hot with time, which impacts crustal reworking and differentiation. However, it remains elusive as to the mechanism driving the crust to be hot during the protracted collision.

REE AND SR MINERALIZATION WITH PERRIERITE-(CE) IN ALKALINE SILICATE-CARBONATE ASSEMBLAGE OF THE CONTACT ZONE OF THE VISHNEVOGORSK BLOCK (SOUTH URALS) [PDF]
The REE and Sr minerals (perrierite-(Ce), allanite-(Ce), ankilite-(Ce), monazite-(Ce), «cerphosforhuttonite») were identified in the apatite-albite-phlogopite-calcite veins of the contact zone of the Vishnevogorsk miaskite block.

OXIDES AND SILICATES OF RARE AND RARE-EARTH ELEMENTS IN ALKALINE ROCKS OF THE ILMENOGORSKY BLOCK (SOUTHERN URALS) [PDF]
A significant part of the REE and rare elements in the rocks of the Ilmenogorsky block forms its own minerals. Oxides and silicates of rare and rare-earth elements in alkaline rocks of Ilmenogorsky block (Southern Urals) include oxynatropyrochlore ...
