PREBIOTIC MORPHOGENESIS VIA NON-EQUILIBRIUM DISSIPATIVE DYNAMICS AND INTERFACIAL INSTABILITIES IN THE EARLY SOLAR NEBULA
- 1Suzhu,China
Abstract
Multiple chemical pathways and thermodynamic mechanisms govern the diversification of prebiotic macromolecular organic networks within primitive protoplanetary reservoirs. This study investigates a complex ternary infiltrative lithologic structure preserved within a primitive, enstatite‑rich anhydrous nebular pebble matrix recovered from a suspected meteorite strewn field in Changshu, Suzhou, China, with a total organic carbon (TOC) content up to 16.84 wt%.
High‑precision rock stable isotope analyses yield reproducible extreme mass‑independent sulfur anomalies (delta34S up to +3002.75 per mil) and extreme nitrogen depletion (delta15N = -158.64 per mil), diagnostic signatures of presolar supernova condensates predating the Solar System. In‑situ plane‑polarized light microscopy reveals geometrically ordered organic microstructures: gear‑like textures, ~25 micrometer honeycomb lattices and closed chambers up to ~500 micrometer. Quantitative image analysis yields steady‑state Gaussian cell‑diameter distributions and a characteristic interfacial wavelength lambda ≈ 50 micrometer, providing observational evidence for Kelvin‑Helmholtz interfacial instabilities initiated at anhydrous fluid‑gel boundaries.
Fourier‑transform infrared spectroscopy (FTIR) and X‑ray diffraction (XRD) measurements indicate that these nanostructures adopt a hierarchically ordered "core‑shell" architecture: dehydrogenated turbostratic polycyclic aromatic hydrocarbon (PAH) cores encapsulated within unbranched aliphatic hydrocarbon shells. The absence of detectable O–H or C=O absorption bands confirms formation under anhydrous conditions. The XRD signal at 2‑theta = 26.57 degree (d = 3.355 Angstrom) corresponds to turbostratic layered carbon domains, which develop preferred orientation during mechanical grinding.
These multi‑scale textures and extreme isotopic signatures record a two‑stage non‑equilibrium fluid‑dynamic evolutionary sequence: first, gas‑phase catalytic formation of polycyclic aromatic hydrocarbon (PAH) cores, followed by the development of reaction‑diffusion patterns and localized interfacial shear dissipation at fluid‑gel boundaries. Parameter estimates demonstrate that the observed characteristic wavelength lambda ≈ 50 micrometer can be physically reproduced by Kelvin‑Helmholtz instabilities driven by effective accelerations arising from gas drag within pebble‑capture environments under microgravity. Statistical topological analysis (Aboav‑Weaire law, narrow Gaussian cell‑size distribution with coefficient of variation CV = 1.80%) rules out an origin via brittle fracture.
The results demonstrate that primitive nebular mineral‑organic materials can assemble complex biomorphic structures via nonlinear energy dissipation, without requiring biological templates or liquid water.
Version 2 update: Added quantitative parameter estimates for Kelvin‑Helmholtz instability under microgravity pebble‑capture conditions; expanded discussion section to rule out alternative brittle fragmentation mechanisms; fixed formula errors, layout inconsistencies and title mismatches; the original geochemical dataset remains unchanged.
