TRIPARTITE DIVISION OF THE SYSTEM 2REEPO 4 – CaTh(PO 4 ) 2 – 2ThSiO 4 , DISCREDITATION OF BRABANTITE, AND RECOGNITION OF CHERALITE AS THE NAME FOR MEMBERS DOMINATED BY CaTh(PO 4 ) 2

The Canadian Mineralogist (2007) 45 (3): 503–508.
DOI: https://doi.org/10.2113/gscanmin.45.3.503
.... The name cheralite has priority over brabantite , which hereby is discredited. A six-fold diagram is replaced by a three-fold nomenclature diagram to conform to IMA rules. The parameters of cheralite are redefined. This proposal, IMA 2005/F, was approved by the CNMMN in April 2006. Abstract La nomenclature...

... of brabantite and the first occurrence of this mineral in a granite. Many new occurrences of cheralite-(Ce), as well as a monazite-group mineral intermediate between monazite-(Ce) and huttonite for which the term huttonitic monazite is proposed, were discovered. Even "common" monazite-(Ce) may show extreme...

American Mineralogist (2000) 85 (1): 22–32.
DOI: https://doi.org/10.2138/am-2000-0104
.... These inclusions are dominated by anhedral allanite, although allanite also occurs rarely as discrete grains not enclosed by monazite. The monazite studied here is relatively homogeneous and characterized by high Th contents with proportions of huttonite (ThSiO 4 ) and brabantite [CaTh(PO 4 ) 2 ] up to 14.6...
