Mechanische und strukturelle Eigenschaften strahlengeschädigter Minerale und der Effekt thermisch induzierter Rekristallisation am Beispiel von Allanit-(Ce), Åskagenit-(Nd) und Pyrochlor

, 2021
In dieser Arbeit wurden drei verschiedene Minerale untersucht, Allanit-(Ce), Åskagenit-(Nd) und Pyrochlor. Alle Proben waren natürlicher Herkunft und hatten Th oder U eingebaut. Alle Proben wurden schrittweise thermisch behandelt und somit ihre strukturelle Ordnung wieder hergestellt.

Tonian shoshonitic to ultrapotassic granitoids from Chhotanagpur Gneissic Complex, Eastern Indian Shield: Age, origin and tectonic implications

Geosystems and Geoenvironment
This work reports petrogenesis of an ultrapotassic granitoid pluton emplaced in the Tonian (949.4 ± 2.3 Ma; new LA-ICPMS zircon U–Pb dating) along a regional shear zone during the post-collisional stage of the Grenvillian Satpura orogeny in Eastern India.
