Regolith stratigraphy at the Chang'E‐3 landing site as seen by lunar penetrating radar

Abstract: The Chang'E‐3 lunar penetrating radar (LPR) observations at 500 MHz reveal four major stratigraphic zones from the surface to a depth of ~20 m along the survey line: a layered reworked zone (<1 m), an ejecta layer (~2–6 m), a paleoregolith layer (~4–11 m), and the underlying mare basalts. The reworked zone has two to five distinct layers and consists of surface regolith. The paleoregolith buried by the ejecta from a 500 m crater is relatively homogenous and contains only a few rocks. Population of buried rocks… Show more

“…Observations at the Chang'E 3 landing site, which was~50 m east of the rim of a~500 m crater, illustrate this point and also show how subsurface rocks remain evident in geophysical data sets, such as ground-penetrating radar (e.g., Fa et al, 2015;Feng et al, 2017).

“…To investigate the effects of gardening on ice deposits that may be older than the Copernican era, we assume that the thickness of mare regolith of known surface age can constrain the unknown thickness of polar ice deposits of the same age. Over the last 3.5 Gyr, impacts have pulverized mare basalts into a regolith layer that is about 3 m thick (Fa & Wieczorek, ; Fa et al, , ; Bart, ; Nakamura et al, ). In Figure we extend our model for gardening beyond the Copernican era and explore how thick an ancient pure ice deposit must have been to have been completely penetrated by impacts.…”

“…The LPR observations at 500 MHz reveal four major stratigraphic zones from the surface to a depth of 20 m: a layered reworked zone (<1 m), ejecta layer (~2-6 m), paleoregolith layer (~4-11 m), and the underlying mare basalts. In addition, the LPR measurements indicate a mean of about 5-10 m/Gyr for the surface regolith, which is at least 4-8 times larger than the previous estimation [14]. These results indicate that the landing site features thin regolith and geological evolution history.…”
