Details

Specimen Number33-6-006Alternate Number65-5-2CommentsMostly a light pink almost cryptocrystalline appearance with patches of coarser-grained material. XRD shows the dark pink areas are predominantly muscovite, the lighter pink areas are microcline + amblygonite + lepidolite, the tan areas are spodumene + lepidolite, and the white areas are microcline + albite. Old label suggests that perthite is present, which may be the case, the diffraction data (see below) can't easily discriminate between admixtures of microcline + albite and actual perthite, need thin section.In Teaching CollectionNoMineral(s)albitelepidolitemicroclineamblygonitespodumenemuscoviteRock NamepegmatiteDistrictPicurisMineHardingExternal LinkMindatDeposit TypePegmatiteGeo-Coords^[1]Donated ByUniversity of Wisconsin-Madison Department of Geoscience
