McFadden J. A.* Thompson M. S. Keller L. P. Christoffersen R. Morris R. V. et al.
Determining Surface Exposure Ages of Regolith Grains in Lunar Core Sample 73002 by Investigating Solar Particle Irradiation Damage [#1767]
Irradiation damage of lunar particles was measured in regolith from the in-situ reworking zone of core sample 73002 to determine exposure age distributions.
Sun L.* Lucey P. G. Flom A. Zeigler R. A. Gross J. et al.
Investigation of Pyroclastic Deposits in Taurus Littrow Valley Using Apollo 17 Core Sample 73001 [#1341]
The black clod we identified from core 73001 has consistent spectral feature with Apollo 17 black beads, and they may share the same pyroclastic origin.
Curran N. M.* Valencia S. N. Corrigan C. M. Bullock E. S. Cohen B. A. et al.
Exposure History of Apollo 17 Double-Drive Tube 73001/73002 [#2206]
Noble gas data from Apollo 17 double-drive tube 73001/2. Data is from particles and soils from six different depths from the core.
Xu L. Y.* Zhang X. Y. Qiao L. Lai J. L. Zhu M.-H.
Thickness of Ejecta Materials at the Chang’E-4 Landing Site and Its Comparison with Yutu-2 Radar Data [#2082]
We thoroughly examine the sources and amounts of foreign materials superposed on the mare basalts at the Chang’E-4 landing site.
Zhang L. Z.* Zhang X. Z. Yang M. Y. Xiao X. X. Qiu D. Q. et al.
New Maps of Major Oxides and Mg # of the Lunar Surface from Additional Geochemical Data of Chang’E-5 Samples and KAGUYA Multiband Imager Data [#1418]
We produced new maps of five major oxides and Mg# with spectral data of MI with the CNN, taking advantage of acquired geochemical information of CE-5 samples.
Cato M. J.* Simon S. B. Shearer C. K.
Modal Petrology of the <1mm Fraction of the Apollo 17 Double Drive Tube 73001/2 and Comparisons with Nearby Samples [#2446]
Here we examined / A new lunar core’s soil / This is what we found.
Carpenter P. K.* Ogliore R. C. Minocha A. Yen C. J-K. Jolliff B. L. et al.
Quantitative Microanalysis Explorer: Next-Generation Tool for Analysis of Apollo 17 Core 73002,6015-6018 [#2573]
Quantitative Microanalysis Explorer is a next-generation web-based microanalysis tool developed to analyze Apollo 17 core samples 73002,6015–6018.
Welten K. C.* Caffee M. W. Masarik J. Nishiizumi K. ANGSA Science Team 
Update on Cosmogenic Radionuclide Depth Profiles in Lunar Core 73002/01 as Part of the ANGSA Program [#2921]
We present depth profiles of cosmogenic 10Be, 26Al, and 36Cl in double drive tube 73002/01, in comparison to expected GCR depth profiles.
Yang M.* Qian Y. Horgan B. H. N. Huang J. Xiao L.
Minerology of Surface Materials at the Chang’E-5 Landing Site and Possible Exotic Sources from In-Situ Spectral Observations [#2055]
Our analysis showed CE-5 regolith is a mixture of two kinds of CPX and Pl. Exotic are dominated by the ejecta from Harpalus and Aristarchus.
Feng J.* Siegler M. A.
Layered Structures in the Upper Several Hundred Meters of the Moon Along the Chang’E-4 Rover’s Traverse [#3034]
We examine the long-term accumulated low-frequency data of CE-4 ground-penetrating radar and find a series of layers in the upper several hundred meters.
