Detailed Mineral List:

β“˜ Albite
Formula: Na(AlSi3O8)
Reference: T. Douglas Schonewald field collected specimens
β“˜ Allanite-(Ce)
Formula: {CaCe}{Al2Fe2+}(Si2O7)(SiO4)O(OH)
Reference: T Douglas Schonewald Collection
β“˜ Allanite-(Ce) var. Nagatelite
Description: see https://www.mindat.org/forum.php?read,6,86773,457331#msg-457331 purported P Ka X-ray line in EDS spectrum is actually Y La; The presence of notable Y-enrichment in the allanite-(Ce) is mineralogically likely and also consistent with the ID of accompanying Y-enriched calcite from the same locality. Proof of P-enrichment requires WDS data.
Reference: Douglas Schonewald collection (EDS-analysed by Pavel Kartashov); purported P Ka X-ray line is actually Y La; Y abundance consistent with accompanying Y-enriched calcite
β“˜ 'Allanite Group'
Formula: {A12+REE3+}{M13+M23+M32+}(Si2O7)(SiO4)O(OH)
Reference: Personally collected by T Douglas Schonewald, Catalog: MI-2016-0019, minID: 837-4AM
β“˜ 'Biotite'
Formula: K(Fe2+/Mg)2(Al/Fe3+/Mg/Ti)([Si/Al/Fe]2Si2O10)(OH/F)2 or Simplified: K(Mg,Fe)3AlSi3O10(OH)2
Reference: T. Douglas Schonewald field collected specimens
β“˜ Calcite
Formula: CaCO3
Description: Y-enriched calcite crust in granitic pegmatite fissure.
Reference: T Douglas Schonewald Collection
β“˜ Epidote
Formula: {Ca2}{Al2Fe3+}(Si2O7)(SiO4)O(OH)
Reference: Collected by Doug Schonewald, Collection of Alex Earl
β“˜ Epidote var. Allanite-Epidote
Formula: {(Ca,REE)2}{Al2Fe3+}(Si2O7)(SiO4)O(OH)
Reference: Collected by Doug Schonewald, Collection of Alex Earl
β“˜ Fluorite
Formula: CaF2
Reference: T. Douglas Schonewald field collected specimens
β“˜ 'Garnet Group'
Formula: X3Z2(SiO4)3
Description: See photo UTL-87W
Reference: T. Douglas Schonewald field collected specimens
β“˜ 'Hornblende'
Reference: T. Douglas Schonewald field collected specimens
β“˜ 'K Feldspar'
Formula: KAlSi3O8

Formula: (K,Ba)AlSi3O8
Description: See child photo of 5XX-60N for analysis graph
Reference: Douglas Schonewald Collection
β“˜ Magnetite
Formula: Fe2+Fe3+2O4
Reference: T. Douglas Schonewald field collected specimens
β“˜ Microcline
Formula: K(AlSi3O8)
Description: Actual analysis was Barian Microcline but was input as Barian K-Feldspar since Barian Microcline does not exist in the database
Reference: T Douglas Schonewald Collection
β“˜ Quartz
Formula: SiO2
Reference: T. Douglas Schonewald field collected specimens
β“˜ Thorite
Formula: Th(SiO4)
Description: Analysis by Pavel Kartashov
