207Pb/206Pb zircon ages and the evolution of the Singhbhum Craton, eastern India: an ion microprobe study
Abstract We used an ion microprobe to measure 207 Pb / 206 Pb ages of single zircons from four key lithologies from the Singhbhum Craton of eastern India. Detrital zircons from the oldest recognizedExpand
Ion microprobe 207Pb/206Pb ages of zircons from the Bundelkhand massif, northern India: implications for crustal evolution of the Bundelkhand–Aravalli protocontinent
Abstract 207Pb/206Pb ages of zircon from gneissic rocks and granitoids representing all major lithological units of the Bundelkhand massif, northern India, have been determined using an ionExpand
Character and Spatial Distribution of OH/H2O on the Surface of the Moon Seen by M3 on Chandrayaan-1
Analysis of recent infrared mapping by Chandrayaan-1 and Deep Impact, and reexamining Cassini data obtained during its early flyby of the Moon, Pieters et al. reveal a noticeable absorption signal for H2O and OH across much of the surface, implying that solar wind is depositing and/or somehow forming water and OH in minerals near the lunar surface, and that this trapped water is dynamic.

Pb–Pb zircon ages of Archaean metasediments and gneisses from the Dharwar craton, southern India: Implications for the antiquity of the eastern Dharwar craton
207Pb–206Pb ages of zircons in samples of metasediments as well as ortho- and para-gneisses from both the western and the eastern parts of the Dharwar craton have been determined using an ionExpand
207Pb-206Pb ages of zircons from the Nuggihalli schist belt, Dharwar craton, southern India
207Pb/ 2 0 6 Pb ages of individual zircon grains from meta-sediments and tonalite trondhjemitic and granitic gneisses in the Nuggihalli schist belt, Dharwar craton are determined by an ionExpand
U–Pb and Hf isotope records in detrital and magmatic zircon from eastern and western Dharwar craton, southern India: Evidence for coeval Archaean crustal evolution
Abstract U–Pb and Lu–Hf isotopic records in detrital and magmatic zircons from the eastern and the western Dharwar craton (EDC and WDC) suggest presence of ≥3.4 Ga crustal components in both theExpand
Mg-spinel lithology: A new rock type on the lunar farside
[1] High-resolution compositional data from Moon Mineralogy Mapper (M3) for the Moscoviense region on the lunar farside reveal three unusual, but distinctive, rock types along the inner basin ring.Expand
The Moon Mineralogy Mapper (M3) imaging spectrometer for lunar science: Instrument description, calibration, on‐orbit measurements, science data calibration and on‐orbit validation
[1] The NASA Discovery Moon Mineralogy Mapper imaging spectrometer was selected to pursue a wide range of science objectives requiring measurement of composition at fine spatial scales over the fullExpand
Gullies and landslides on the Moon: Evidence for dry-granular flows
[1] High-resolution images from Chandrayaan-1 Terrain Mapping Camera and Lunar Reconnaissance Orbiter Camera reveal landslides and gully formation on the interior wall of a 7 km-diameter simpleExpand
