The double drive tube core sample (73001/73002), collected at Station 3 during the Apollo 17 mission, penetrated a lunar landslide deposit that was transported from the slope of the South Massif into the TLV (Figure 1). Orbital data suggest that this deposit represents multiple events that were triggered by movement along the Lee-Lincoln scarp [e.g., 1] or impact events [e.g., 2,3]. Although numerous core and trench samples were collected during the Apollo pro-gram and numerous landslide deposits have been identified on the lunar surface by orbital missions [e.g., 3], the Station 3 double drive tube is the only core that penetrated a landslide deposit. The intentions of our study are: to establish the stratigraphy of the deposit; to better understand the processes at work during the event(s), including the role of volatiles in the event(e.g., fluidization-enabled flow, escape of fluidizing volatiles) [1] and the capability of deposits for trapping indigenous volatiles; the number of landslide events; and the trigger(s) of such events. Here, we report some initial petrologic observations of the < 1mm fraction of the regolith. A companion abstract [4] emphasizes <1 mm lithic fragments, compares them to surface lithologies, and to > 4 mm lithic fragments.
