Mineralogy and Beneficiation of Lamujärvi Syenites [PDF]
, 2020 The Lamujärvi syenites intrusions occur within Svecofennian (ca. 1.92 Ga) gneisses, ca. 70 km west of the Otanmaki alkaline area in central Finland. Previous studies have revealed zones in the syenites that display strong enrichment in Zr (1587 ppm), Nb (

Mechanisms for the generation of HREE mineralization in carbonatites: Evidence from Huanglongpu, China. [PDF]
, 2019 The Hunaglongpu carbonatites, Qinling Mountains, China, are exceptional as they form both an economic Mo resource, and are enriched in the HREE compared to typical carbonatites, giving a metal profile that may closely match projected future demand.
