The analysis for this specimen showed a core of ferrokentbrooksite with a shell of manganokhomyakovite. However this particular xl may have a different structure. It is impossible to distinguish eudialyte group members visually at MSH. For this particular occurence I estimate that ferrokentbrooksite >> manganokhomyakovite > khomyakovite. But this is based on just 7-8 analyses that I know of",904,[],[330,331,332],"Ferrokentbrooksiet","IMA1999-046","Xanthopite",[334,338,343,347,350],{"lang":335,"names":336},"ca",[337],"ferrokentbrooksita",{"lang":339,"names":340},"de",[341,342],"Ferrokentbrooksit","IMA 1999-046",{"lang":344,"names":345},"eu",[346],"Ferrokentbrooksita",{"lang":348,"names":349},"it",[7],{"lang":351,"names":352},"pl",[353],"Ferrokentbrooksyt","Q3743246",{"history":11,"applications":11}]
