| Abstract: | Highlights: What are the main findings? Established the Jingpo Lake Volcanic Field (JLVF) as a high-fidelity terrestrial analog for the lunar Marius Hills through a systematic morphometric continuum. Identified a "U-to-V" cross-sectional transition in collapse trenches, confirming that lunar sinuous rilles originate from tube-roof failure. What are the implications of the main findings? Provides a new geological model to explain the transition from subsurface lava tubes to open sinuous rilles on the Moon. Offers high-resolution terrestrial data to fill the gap caused by the lack of sub-meter scale lunar orbital imagery. The lack of high-precision imaging data for lunar volcanic regions currently hinders the detailed characterization of lava tube systems and their associated fine-scale geomorphology. To address this information deficit, this study establishes the Jingpo Lake Volcanic Field (JLVF) in Northeast China as a primary terrestrial analog for the lunar Marius Hills complex. We systematically characterize the basaltic morphometric continuum, tracing the geological evolution from proximal scoria cones through medial lava tube skylights to distal lava plateaus. Focusing on the subsurface transport system, we identify a linear chain of discontinuous skylights that structurally mirrors the "proto-rille" stage of lunar sinuous rilles. Quantitative morphometry reveals that these terrestrial vents reproduce the geometric duality of lunar pits, ranging from stable "deep shafts" to degraded "funnel pits," effectively validating the mechanical diversity of the lunar inventory. Critically, the "U-to-V" cross-sectional transition observed in JLVF collapse trenches serves as diagnostic ground-truth evidence, confirming that lunar rilles originate from the catastrophic roof failure of subsurface tubes rather than purely thermal erosion. Regarding the lava plateau, our field investigation resolves sub-meter micro-textures—including laminar pahoehoe ropes and inflation fissures—that are typically obscured by the resolution limits of current lunar orbiters. These findings suggest that the seemingly "smooth" lunar maria likely host complex, rugged micro-terrains. Therefore, comparing lunar volcanic regions with simulated volcanic fields from Earth is crucial. Analyzing potential volcanic products from angles undetectable by some lunar satellites can offer vital insights for future lunar exploration. [ABSTRACT FROM AUTHOR] |
