    pubs.er.usgs.gov/publication/70017512 Hogtuvaite is a new beryllian member of the aenigmatite group that was discovered in Nordland County, Norway. It is a metamorphic mineral, hosted by Proterozoic granitic gneisses and mafic pegmatites of metamorphic origin. Compositional variations within and between gneiss-hosted samples of hogtuvaite are minimal; however, pegmatite-hosted samples of hogtuvaite are significantly different ...

  • VECTOR REPRESENTATION F SOME MINERAL COMPOSITIONS IN THE ...

    citeseerx.ist.psu.edu/viewdoc/summary Hogtuvaite is derived by BeSiAl-2 acting on rhtlnite, and welshite by AlSbBe(MgTiSi)_1 acting on hpgtuvaite. Other theoretical end-members can be generated by the vector method; in the aenigmatite group, many are probably unstable with regmd to a mixture of clinopytoxene plus olivine or spinel, especially if they lack Ti or excess A1.
