Table T4. Proposed analyses of the communal glass samples.
Measurement | Investigator | Number of analyses | Aliquot |
---|---|---|---|
Fourier transform infrared spectroscopy water | Armstrong, Robin | 5 to 10 | 5 mm chips |
Microprobe for major elements | Fisk, Martin | 30 to 40 + 20 thin sections | 5 mm chips and thin sections |
Microprobe and optical microscopy for biological alteration | Fisk, Martin | 20 thin sections | thin sections |
Ion probe for C, S, and trace element distribution and Pb isotopes | Ludden, John | 10 to 20 | 1 to 5 mm bio + chips |
LA-ICP-MS for trace elements | Plank, Terry | 20 to 30 | >1 mm chips |
Ion probe for S, Se, metals | Rouxel, Olivier | same 10-20 chips of Ludden | 1 to 5 mm bio + chips |
Mass spectrometry Sr, Nd, Pb isotopes | Schmidt, Angelika | 1 | 0.5 g |
Cl isotopes and halogens | Spivack, Arthur | 2 to 3 | 250 mg |
Microscopy of biological alteration | Staudigel, Hubert | same as/share with Fisk | thin sections |
Magnetic intensity | Steiner, Maureen | 10 to 12 | 50 mg |
Li, B isotopes | Valentine, Robbie | 2 | 1 g |
N isotopes | Bebout | 2-3 | <1 g |
Note: LA-ICP-MS = laser ablation-inductively coupled plasma-mass spectrometry.
