We are still strongly involved in standard development for isotopic and trace element analyses on minerals and glasses of geological interest.

Here is a list of reference material available in our lab:

Glasses:

• International: NIST, MPI-DING, BHVO, BIR, BCR (trace elements, Li, B, O, Si, Fe isotopes)
• In house: 5 basaltic glasses (d¹⁸O, d³⁷Cl; ²⁶Mg/²⁶Al, ²⁶Mg/²⁴Mg), different glasses for water and dD

Note that glasses could be used as trace elements standards for some minerals (Trace element analyses are only performed if the project cannot be done by LA-ICP-MS).

Minerals:

• Apatite (d³⁴S, d³⁷Cl)
• Quartz (d¹⁸O, d³⁰Si, trace elements)
• Biotite (d¹⁸O, Cl, F, H₂O)
• Micas (d¹⁸O)
• Garnet (d¹⁸O, d⁷Li)
• Feldspars (d¹⁸O)
• Albite (d¹⁸O, d³⁰Si)
• Pyroxene (d⁷Li¸ low and high Ca- pyroxene: ²⁶Mg/²⁶Al, ²⁶Mg/²⁴Mg)
• Tourmaline (d¹⁸O; d¹¹B)
• Graphite (d¹³C)
• Carbonate: dolomite, calcite, siderite (d¹³C, d¹⁸O, and d⁵⁶Fe for siderite only)
• Sulfide (d³⁴S, d⁵⁶Fe)
• Olivine (d¹⁸O: Fo 74 – 98.5, d⁵⁶Fe: ~Fo90; ²⁶Mg/²⁶Al, ²⁶Mg/²⁴Mg: Fo 76 – 99)
• Monazite (except Ca-rich; d¹⁸O, U-Pb dating)
• Zircon (d¹⁸O, U-Pb dating)
