Single crystal structure analyses of scheelite-powellite CaW1-xMoxO4 solid solutions and 

unique occurrence in Jisyakuyama skarn deposits


I do research about two minerals



Jisyakuyama skarn deposit, 




Place where we took sample
:Fukuchi, Fukuoka, Japan




Characteristic
A unique occurrence of scheelite-powellite CaW1-xMoxO4 minerals is observed in the skarn deposit. 



The Minerals are fluorescent materials. 






How to do
It is known that a complete continuous solid solution is formed even at room temperature. In this

study, we have carried out the chemical analyses, crystal structural refinements

and detail description of occurrence on scheelite-powellite minerals. We have 

also attempted synthesis of single crystal of solid solution in a wide composition 

range. The chemical compositions were determined by JEOL scanning electron 

microscope and EDS, INCA system. We have performed the crystal structure 

refinements of the scheelite-powellite CaW1-xMoxO4 solid solutions (x=0.0-1.0)

 by RIGAKU single-crystal structure analysis system RAPID. 




Hope
This research can be expected to lead to giving restrictive conditions to elucidate 

the mineralization process.
