Data are presented for the six new Chinese rock standards, GSR 1 through 6. These samples include a granite, an andesite, a basalt, a sandstone, a shale, and a limestone, providing a wide range of sample types of geochemical interest. The certificate values were tested using XRF and ITNA for the major and trace elements and colorimetry, coulometry, and thermogravimetry for the ferrous iron and the volatile constitutents. Excellent agreement was obtained for the 50 elements measured, implying these standards have been well characterized generally and should be of immediate use to geochemists.
