A review of lava flow processes related to the formation of lunar sinuous rilles

Abstract: Abstract. This paper reviews processes which, it is argued, occurred in lunar lava flows and were involved in the formation of lunar sinuous rifles.The development of ideas relating to rille formation is described and evidence which suggests that they are products of lava effusions is outlined.An analytical lava flow model is described which relates the shapes of lava flows to conditions at the commencement of the flows. An essential part of the model is its use of the yield strength of lava as a parameter. It… Show more

“…Unfortunately, the only way of estimating the thickness of the precursor flow itself involves assumptions about the volume eruption rate and rheological properties of the lava. We therefore begin by assuming a We next evaluate the heat fluxes from the lava to the substrate due to viscous dissipation G and conduction through the laminar boundary layer in contact with the ground C. These are given by Hulme [1982]:…”

“…Using the MOLA data, the slopes for the various channel segments are estimated to be 8.5 ø for the proximal "old" part of the channel, 10.0 ø for the vent area, 8.9 ø for the main part of the channel, and 7.1 o for the distributed channel. The concept that a long-lived, high effusion rate volcanic eruption could create an incised channel, rather than a conventional lava flow, was developed to explain the presence of the meandering channels called sinuous rilles on the Moon which must have been formed in the complete absence of water [Hulme, 1973[Hulme, , 1982Cart, 1974]. The volcanic mechanism involves the transfer of enough heat into the surface beneath the lava to raise its temperature to the point where purely thermal erosion (as assumed by Hulme [1973] Fagents and Greeley, 2001] emphasizes that the erosion process is most pronounced when the lava effusion rate and temperature are high, the lava viscosity is low, and the ground over which the initial flow moves is steep and has low mechanical strength.…”

“…Me an der ing chan nels could also be a re sult of lava flow, e.g. on the Moon (Hulme, 1973). Therefore, we be lieve that our in ves ti ga tions could have some value not only for un der stand ing pro cesses on Ti tan but also for general knowl edge of flu vial pro cesses.…”

“…Among these features are meandering channels or canali which range up to -6800 km in length. These channels occur mainly on the planitia and are similar in some respects to lunar sinuous rilles, which are widely believed to have been produced by very low viscosity, high Fe-Ti-rich basaltic lava flows [Hulme, 1973].…”

“…The residual, unmelted material may be transported by the fluid and deposited downstream within the channel (leading to braiding) or as levees and other types of overbank deposits. Essential requirements of this process are that the lava contain sufficient heat to raise the temperature of the substrate to that of its solidus, and that flow be turbulent [Hulme, 1982]. The latter condition is also necessary in order to permit transport of residual, unmelted material.…”
