9 valid minerals. 1 (TL) - type locality of valid minerals.

Detailed Mineral List:

Aegirine
Formula: NaFe3+Si2O6
Reference: William S. Wise (1982) Strontiojoaquinite and bario-orthojoaquinite: two new members of the joaquinite group . American Mineralogist 67:809-816.
Albite
Formula: Na(AlSi3O8)
Description: Occurs as linings of fractures in blueschist.
Reference: Pemberton, H. Earl (1983), Minerals of California; Van Nostrand Reinholt Press: 470; www.mineralsocal.org; William S. Wise (1982) Strontiojoaquinite and bario-orthojoaquinite: two new members of the joaquinite group . American Mineralogist 67:809-816.
Benitoite
Formula: BaTi(Si3O9)
Reference: William S. Wise (1982) Strontiojoaquinite and bario-orthojoaquinite: two new members of the joaquinite group . American Mineralogist 67:809-816.
Calcite
Formula: CaCO3
Colour: White opaque.
Fluorescence: Often pinkish red under Short Wave UV light.
Reference: Personally collected and analyzed by David Lowe. White Calcite fills large vugs with thin off-white fibrous Pectolite veins crossing and surrounding. Minor Albite and an amorphous phase are present as well. XRD reference patterns: PDF 04-007-8659, PDF 04-011-5155, and PDF 01-084-0752.
'Crossite'
Reference: William S. Wise (1982) Strontiojoaquinite and bario-orthojoaquinite: two new members of the joaquinite group . American Mineralogist 67:809-816.
Ferri-winchite
Formula: ☐[CaNa][Mg4(Fe3+,Al)]Si8O22(OH)2
Reference: A piece of blueschist matrix often called "Crossite" was personally collected and analyzed by David Lowe. It contained Ferri-Winchite matching reference XRD pattern PDF 00-052-1577 and Albite PDF 01-084-0752. It was in direct contact with Neptunite, which was separately found to match PDF 00-043-0677. No other crystalline phases were found.
Joaquinite-(Ce)
Formula: NaBa2Ce2FeTi2[Si4O12]2O2(OH,F) · H2O
Reference: Mineralogical Research Company
Neptunite
Formula: Na2KLiFe2+2Ti2Si8O24
Reference: www.mineralsocal.org; William S. Wise (1982) Strontiojoaquinite and bario-orthojoaquinite: two new members of the joaquinite group . American Mineralogist 67:809-816.
Pectolite
Formula: NaCa2Si3O8(OH)
Colour: Off-white.
Fluorescence: Can be light yellow under Short Wave UV light.
Reference: Collected by Charles "Chuck" Trantham. Analyzed by David Lowe. Vein inside tough blueschist matrix. Opaque white with very thin pink layer on top, which may be Serandite. Associated with Albite. Most samples are thin veins of short needles in Calcite and have no color.
Strontiojoaquinite (TL)
Formula: Sr2Ba2(Na,Fe)2Ti2[Si4O12]2O2(O,OH)2 · H2O
Type Locality:
Habit: Steep pseudotetragonal, bipyramidal.
Colour: Green, yellow-green, yellow-brown (uncommon)
Description: Occurs in the New Idria serpentinite body in albite-lined fractures cutting blueschist.
Reference: Pemberton, H. Earl (1983), Minerals of California; Van Nostrand Reinholt Press: 470; www.mineralsocal.org; William S. Wise (1982) Strontiojoaquinite and bario-orthojoaquinite: two new members of the joaquinite group . American Mineralogist 67:809-816.
