Lava Flow Eruption Conditions in the Tharsis Volcanic Province on Mars

Abstract: The large thick lava flows in Tharsis are explained by basaltic and basaltic-andesite compositions without resorting to exotic compositions.-The observed lava flows likely required longer-lived eruptive conditions and larger active conduits than their terrestrial counterparts.-Seemingly high eruption rates for some solitary flows are reasonable extrapolations of terrestrial conditions with higher supply dimensions.

“…This thickness is within the range measured for the other flow fields with basal reflectors identified by SHARAD and the thicknesses calculated by Peters et al. (2021). SHARAD should be able to penetrate to the base of such a flow under ideal conditions (e.g., low loss tangent).…”

“…Primary basalts are produced by decompression melting of the mantle in rising plumes, a process that likely produced a significant fraction of the crust (S. R. Taylor & McLennan, 2009) and has persisted until recently in the Tharsis and Elysium volcanic provinces (Horvath et al., 2021; Peters et al., 2021; Richardson et al., 2021; Werner, 2009). Several near‐primary basalts, analyzed in situ or sampled as meteorites are well characterized and their study has the potential to shed light on the mantle melting process (Collinet et al., 2017; Filiberto, Dasgupta, et al., 2010; McSween, Wyatt, et al., 2006; Monders et al., 2007; Musselwhite et al., 2006; Udry et al., 2014, 2020).…”
