Abstract

The water content of the breccia is 150 to 455 ppm, with a δD from—580 to —870 per mil. Hydrogen gas content is 40 to 53 ppm with a δD of —830 to —970 per mil. The CO2 is 290 to 418 ppm with δ 13C = + 2.3 to + 5.1 per mil and δ18O = 14.2 to 19.1 per mil. Non-CO2 carbon is 22 to 100 ppm, δ13C = —6.4 to —23.2 per mil. Lunar dust is 810 ppm H2O (D = 80 ppm) and 188 ppm total carbon(δ13C = —17.6 per mil). The 18O analyses of whole rocks range from 5.8 to 6.2 per mil. The temperature of crystallization of type B rocks is 1100° to 1300°C, based on the oxygen isotope fractionation between coexisting plagioclase and ilmenite.
