abstract |
Northwest Africa (NWA) 10989 is a recently found lunar meteorite we used to elucidate
the history of volatiles (H and Cl) in the Moon through analysis of its phosphates.
The petrology, bulk geochemistry and mineralogy of NWA 10989 are consistent with it
being a lunar meteorite with intermediate-iron bulk composition, composed of 40% of
mare basaltic material and ~ 60% non-mare material, but with no obvious KREEP-rich
basaltic components. It is probable that the source region for this meteorite resides
near a mare–highlands boundary, possibly on the farside of the Moon. Analyses of chlorine
and hydrogen abundances and isotopic composition in apatite and merrillite grains
from NWA 10989 indicate sampling of at least two distinct reservoirs of volatiles,
one being similar to those for known mare basalts from the Apollo collections, while
the other potentially represents a yet unrecognized reservoir. In situ Th-U-Pb dating
of phosphates reveal two distinct age clusters with one ranging from 3.98 ± 0.04 to
4.20 ± 0.02 Ga, similar to the ages of cryptomare material, and the other ranging
from 3.32 ± 0.01 to 3.96 ± 0.03 Ga, closer to the ages of mare basalts known from
the Apollo collections. This lunar breccia features mixing of material, among which
a basaltic D-poor volatile reservoir which doesn’t appear to have been recorded by
Apollo samples. |
