| Abstract: | A second mineral from the Kakanui Mineral Breccia, an anorthoclase, has been prepared as an international microprobe standard. The K2O content may be variable. Major and trace element contents are tabulated. Relatively high Sr (2260 ppm) and Ba (622 ppm) may make this mineral a useful trace element standard. |
