Session Introduction

8:25 AM

Mechem M. E.* Hostrawser J. W. Osinski G. R.

Revisiting the Nomenclature of Apollo 16 Impactites [#2640]
Two Apollo 16 lunar impactite thin sections were studied via microscopy, XRF, and EPMA to revisit their potentially outdated nomenclature.

8:35 AM

Bhanot K. K. Downes H.* Rider-Stokes B. G.

Lunar Dunite 72415: New Interpretations of Olivine Textures and Inclusions [#1915]
Mineral inclusions in olivine clasts in lunar dunite 72415 imaged in BSE and CT explain previous studies of “zoning.” EBSD data suggest 60-GPa impact pressure.

8:45 AM

McLeod C. L.* Brum J. T. Loocke M. P. Shaulis B. Gawronska A.

Allan Hills (ALHA) 81005 40 Years On: New Insights from Dunitic and Troctolitic Mg-Suite Clasts [#2979]
Mg suite clasts in the first lunar meteorite, Allan Hills (ALHA) 81005, olivine and spinels from a dunite and from troctolites have a story to tell.

8:55 AM

Sheikh D.* Ruzicka A. Hutson M. Zlimen C.

Pink Spinel Anorthosite (PSA) Clasts in Lunar Dimict Breccia Northwest Africa (NWA) 15500: Evidence for a Petrogenetic Link Between PSA and Mg-Suite [#2066]
Pink spinel anorthosite clasts found in NWA 15500 display textural/chemical evidence indicating a petrogenetic relationship to Mg-suite pink spinel troctolites.

Simon S. B.* Shearer C. K. ANGSA Science Team 

Spinel-Bearing Igneous Lithic Fragments from Apollo 17 Double Drive Tube 73001/73002 [#2265]
Spinel-bearing lunar igneous rocks are rare but important. We report the mineralogy and petrology of examples from the recently opened A-17 double drive tube.

9:35 AM

Yen C. J.-K.* Carpenter P. K. Jolliff B. L. Ogliore R. C. Kent J. J. et al.

Chemistry and Mineralogy of 73002,455 from Clast 1017C: A Texturally Unique Olivine Porphyritic Very Low-Ti Basalt [#2840]
Still unusual / In texture and minerals / Probe gives new insights.

9:45 AM

Galien L. E.* Neal C. R.

Textural Analysis of Pyroxene in Apollo 11 (A-11) High-Ti Basalts [#2793]
Pyroxene crystal size distributions were conducted on 14 A-11 samples to investigate basalt cooling histories.

9:55 AM

Warren P. H.* McKeegan K. D. Matsuda N. Ma C.

Crystalline, Hibonite-Bearing HASP Clasts in Lunar Meteorite Northwest Africa 2420 [#2548]
We have discovered HASP consisting of stable (not metastable yoshiokaite) crystals, including hibonite and gehlenite, in two meteorite clasts.

Davis J. R.* Crow C. A. Economos R. Lehman Franco K. Erickson T.

The Lost Lunar Zircons: How Sample Processing has Biased the Apollo Zircon Record [#2985]
A biased record? / Some Apollo zircons are hiding / Lunar mystery!

10:35 AM

Nemchin A. A.* Merle R. Whitehouse M. J. Snape J. F. Connelly J. N. et al.

Radiogenic Isotopes in Lunar Basalts [#1856]
This presentation attempts to evaluate radiogenic isotopes datasets available for lunar basalts and what they can tell us about heterogeneity of lunar mantle.

10:45 AM

Florin G.* Gleißner P. Becker H.

Zinc Isotopic Composition of Lunar High- and Low-Titanium Mare Basalts [#2124]
We report the first Zn isotopic measurements by Neoma MC-ICP-MS on lunar samples and show a resolvable difference between low-Ti and high-Ti mare basalt.

10:55 AM

Srivastava Y.* Basu Sarbadhikari A. Day J. M. D. Yamaguchi A.

A 187Re-187Os and Highly Siderophile Element Study of the KREEP-Free YAMM Basalts [#2086]
Examining highly siderophile elements and 187Os/188Os in 3.9-Ga KREEP-free YAMM basalts provides insight into internal and external processes on the Moon.
