<div>Title: <i>Lunar Nearside-Farside Mare Basalt Asymmetry: The Combined Role of Global Crustal Thickness and South Pole-Aitken Basin-Induced Lithospheric Thickening</i></div>
<div><br>
</div>
<div>Abstract: The first acquisition of lunar farside images by Luna 3 in 1958 revealed a substantial NS/FS asymmetry in mare basalt (MB) deposits,. In the following decades, many additional NS/FS asymmetries have been documented (e.g., albedo, topography,
crustal thickness, composition (heat producing element (HPE), iron, titanium), terrane types, etc.). Among the explanations for the MB asymmetry are: asymmetric accretion; asymmetric degree 1 convection thickens crust; SPA basin impact or other factors bringing
HPE to NS PKT terrain; asymmetric LMO convection; incomplete post-LMO residual layer foundering; late-stage LMO impact events, etc., all potentially causing, or contributing to, the NS/FS mare basalt asymmetry observed . We investigate the key causative factors
in the observed NS/FS mare basalt asymmetry and propose that it is due to two combined factors: NS/FS crustal thickness, and SPA basin event-accelerated lithospheric thickening.</div>
