New SHRIMP-RG methods paper, and values for MAD and MADDER!

A new paper is now published in Geostandards and Geoanalytical Research, outlining methods for U-Th-Pb and trace element analyses in zircon using SHRIMP-RG. Also included are trace element concentrations for MADDER (now called MAD-559), as well as updated values for MAD-green, 91500, CZ3, and SL13 zircon standards. 

We provide an updated value for Ti for all these standards, based on robust isotope dilution ICP-MS measurements of 91500 by Szymanowski et al. (ChemGeol; 2018). We also include conversion factors to update previous trace elements concentrations to updated values presented here (see Supplemental Table 8).
