| الملخص: | <p dir="ltr">The Light Mantle landslide deposit in Taurus-Littrow Valley, on the Moon, was one of the geological targets of the Apollo 17 mission, as scientists wanted to understand how it formed and which mechanism was responsible for its long runout. A cylindrical sample of the top 70 cm of the Light Mantle deposit, made up of two sections, was collected by Apollo 17 astronauts and kept closed for almost 50 years. As part of the NASA Apollo Next Generation Sample Analysis (ANGSA) initiative, the sample has been recently opened and it has been made available for study. We used X-ray Computed Tomography (XCT) scans of sample 73002 and, for the first time on a lunar core sample, we conducted a 3D analysis of the clast size distribution.</p><p dir="ltr">The data analysis and visualization of the XCT dataset of core sample 73002 were performed using 3D visualization software Avizo 2022.2 by ThermoFisher at the Micro-CT lab, Imaging and Analysis centre at the Natural History Museum, London.</p><p dir="ltr">The Excel spreadsheet contains the record of the 674044 identified clasts (Barycentre position, Equivalent Diameter, Volume).</p> |
