Description: According to Olav Revheim 2016 The katophorite analysis presented in "CURRIE,K.L.& VAN BREEMEN, O. (1996). The origin of rare minerals in the Kipawa syenite complex, Western Quebec. Canadian Mineralogist Vol. 34, pp.435" are used as reference both for katophorite and ferro-katophorite from Kipawa, even though only one analysis is presented, mindat is therefore presenting two minerals from one analysis. The normalized composition provided by them gives a total A content >1.3, normally indicating that something is not right with the analysis, but if the high A content is ignored, the "katophorite" corresponds to a potassic-ferro-ferri-katophorite. I woould suggest that the katophorite is striked out and ferro-katophorite are deleted and potassic-ferro-ferri-katophorite is added with a question mark, based on Currie and Van Bremen's analysis. (Since 1996, there has been two amphibole nomenclature reports and katophorite has been redefined)

Description: Structure was solved on Kipawa material.

Description: Thus far every specimen of Mosandrite that has been analyzed has turned out to be Rinkite. RAMAN is required to distinguish the two.

Description: Vlasovite came from a place called the vlasovite pit which was collected by the Canadian National Museum. Another pit was called the eudialyte pit and here the best specimens rich in eudialyte associated with vlasovite eyes, rimed with gittinsite which is the type locality for that mineral. The largest “eyes” measure up to about 2x3 inches but are more commonly about a half inch in diameter. It fluoresces a butter yellow under short-wave ultraviolet light. The pit is about 10x30 feet and about eight feet deep. The material appears to have been worked out. The material is a honey yellow color. About 400 lbs. of specimens (about 40 flats) were collected by Derryl MacFarlane . The mineral was found in surface workings. Discovered in 1955 by a Canadian government airborne radiometric survey. It was originally thought to be a uranium deposit but it turned out to be only rich in thorium. Unical company, a subsidiary of US Moly Corp, the company that mines Mountain Pass, California was interested in it for the zirconium and yttrium. It turned out not to be rich enough to make a mine. They cleared out about five acres on the shore of the lake for a camp. They used a skidder to clear an approximate 3 km strip along the outcrop of the complex and striped down to bedrock every 250 meters and washed the surface clean. Sampling and drilling indicated it was not worthwhile to mine, but they spent about a million dollars on development. This gave them the mineral rights for 65 years. There were over fifty claims on the complex. Derryl MacFarlane got involved in working the deposit for specimens in 1991 and concentrated in working a rich eudialyte pegmatite in the complex. The associated minerals are eudialyte, agrellite, vlasovite, gittinsite, mosandrite (rinkite”), calcite richterite, white feldspar, fluorite, thorite, and galena. The only access to the deposit is by boat or helicopter. ( Rock Currier, 2009, Darryl MacFarlane 2005.)
